a corresponding set of tones will indicate the
channel.
A. General
The HT 1000, MT 2000, MTS 2000, and MTX series
radios have been prepared to meet published specifications through their manufacturing process, with the use
of laboratory-quality test equipment of highest accuracy.
The recommended field service equipment approaches
the accuracy of the manufacturing equipment with a few
exceptions. Accuracy of the equipment must be maintained in compliance with the manufacturer's
recommended calibration schedule.
(d) Pressing SB2 will scroll through and access test
environments as shown in Table 40-5.
NOTE
Transmit into a load when keying a radio under
test.
To exit test mode, turn the radio off then back on.

C. Test Mode
1. RF Test Mode, HT 1000 Radios
When the HT 1000 radio is operating in its normal
environment, the radio's microcontroller controls the
RF channel selection, transmitter key-up, and
receiver muting. However, when the unit is on the
bench for testing, alignment, or repair, it is removed
from its normal environment. It cannot receive commands from its system and, therefore, the internal
microcontroller will not key the transmitter nor
unmute the receiver. This prevents the use of normal tune-up procedures. To solve this problem a
special routine, called TEST MODE or “air test,” has
been incorporated in the radio.
To enter test mode:
(a) Turn the radio on.

2. Control Head Test Mode, HT 1000 Radios
To check the buttons and the switches, perform the
following tests:
(a) Turn radio on
(b) After the self test is complete, press the monitor
button (side button 3, SB3) five times in succession, within 10 seconds. After the fifth press, a
tone is emitted to indicate that the RF test mode
has been entered.
(c) Exit the RF test mode and enter the control
head test mode by pressing and holding SB3
for more than three seconds. Upon entering the
control head test mode, a tone is emitted and
the green LED begins flashing. The green LED
continues to flash until the control head test
mode is exited.
NOTE
Return to the RF test mode by pressing and holding SB3 for more than three seconds. Then
re-enter the control head test mode by pressing
and holding SB3 for more than three seconds.
(d) Test each switch (toggle, rotary, or button-actuated) by changing the position of the switch. A
tone is emitted to indicate a “good test“ each
time a switch position is changed.
NOTES
1.
Pressing and releasing a button-actuated
switch are both considered switch-position
changes.
2.
No tone when a switch position is changed
indicates a test failure.

(e) Test the on/off volume potentiometer/switch by
rotating the potentiometer clockwise and counter

increase and decrease accordingly.
NOTE
During test mode, the volume level is not regulated
to the same limits as during normal radio operation.
To exit test mode, turn the radio off then back on.
3. RF Test Mode, MT 2000, MTS 2000, and MTX
Series Radios
When the MT 2000, MTS 2000, or MTX series radio
is operating in its normal environment, the radio's
microcomputer controls the RF channel selection,
transmitter key-up, and receiver muting. However,
when the unit is on the bench for testing, alignment,
or repair, it is removed from its normal environment.
It cannot receive commands from its system and,
therefore, the internal microcomputer will not key the
transmitter nor unmute the receiver. This prevents
the use of normal tune-up procedures. To solve this
problem a special routine, called TEST MODE or “air
test,” has been incorporated in the radio.
To enter test mode:

IV. ERROR CODE DISPLAYS
A. Power-up Display Codes
B. Operational Display Codes
At power-up, the radio performs cursory tests to
determine if its basic electronics and software are in
working order. Problems detected during these tests are
presented as error codes on the radio display. The presence of an error code should prompt the user that a
problem exists and that a service technician should be
contacted.
During operation, the radio performs dynamic tests
to determine if it is working properly. Problems detected
during these tests are presented as error codes on the
radio display. The presence of an error code should
prompt a user that a problem exists and that a service
technician should be contacted. Use Table 40-12 to
aid in understanding particular operational error code
displays.
Self-test errors are classified as either fatal or nonfatal. Fatal errors will inhibit user operation, while
non-fatal errors will not. Use Table 40-11 to aid in understanding particular power-up error code displays.

Figure 40-2. RSS Service Menu Layout
All service and tuning procedures are performed from
the SERVICE menu, which is selected by pressing F2
from the MAIN MENU. Figure 40-2 illustrates how the
RSS SERVICE screens are organized.
All SERVICE screens read and program the radio codeplug directly; you do NOT have to use the RSS
GET/SAVE functions to use the SERVICE menus. You
will be prompted at each screen to save changed values
before exiting the screen. RSS references in this manual are to HT 1000 RSS. Some slight differences may be
noted it you are using the MTS/MTX RSS.
!
Each SERVICE screen provides the capability to
increase or decrease the ‘softpot’ value with the keyboard UP/DOWN arrow keys respectively. A graphical
scale is displayed indicating the minimum, maximum,
and proposed value of the softpot, as shown in
figure 40-3.
CAUTION
Do NOT switch radios in the middle of any
SERVICE procedure. Always use the EXIT
key to return to the MAIN menu screen before
disconnecting the radio. Improper exits from
the SERVICE screens may leave the radio in
an improperly configured state and result in
seriously degraded radio or system performance.
The radio contains internal test modes that can be
accessed from the RSS. The test modes permit the service technician to easily select various frequency,
modulation, and transmit power combinations to verify
proper operation of the radio. The test modes can be
used to check both transmit and receive operation.
From the Service Menu press F6 to navigate to the
TEST MODE screen.
12
The SERVICE screens introduce the concept of the
“softpot”, an analog SOFTware controlled POTentiometer used for adjusting all transceiver alignment controls.
MAEPF-22858-O
Figure 40-3. Softpot Concept
Adjusting the softpot value sends information to the
radio to increase (or decrease) a DC voltage in the corresponding circuit. For example, pressing the UP arrow
key at the Reference Oscillator screen instructs the
radio microprocessor to increase the voltage across a
varactor in the reference oscillator to increase the
frequency.
In ALL cases, the softpot value is just a relative
number corresponding to a D/A (Digital-to-Analog) generated voltage in the radio. All standard measurement
procedures and test equipment are similar to previous
radios.
Perform the following procedures in the
sequence indicated.
8. Press F10 and F2 to return to the RECEIVER
menu.
B. Reference Oscillator Alignment
D. Rated Audio
Adjustment of the reference oscillator is critical for
proper radio operation. Improper adjustment will not
only result in poor operation, but also a misaligned radio
that will interfere with other users operating on adjacent
channels. For this reason, the reference oscillator
should be checked every time the radio is serviced. The
frequency counter used for this procedure must have a
stability of 0.1 ppm (or better).
1. Set test box (RTX-4005B) meter selection switch to
the “AUDIO PA” position and connect an ac voltmeter to the test box ac/dc meter port.
1. From the SERVICE menu, press F2 to select
TRANSMITTER alignment.
2. Press F2 again to select the REFERENCE OSCILLATOR softpot.

SECTION VI. DISASSEMBLY AND REASSEMBLY
B. Disassembly to Board Level
!
CAUTION
THIS RADIO CONTAINS STATIC-SENSITIVE DEVICES.
DO NOT OPEN THE RADIO UNLESS PROPERLY
GROUNDED. TAKE THE FOLLOWING PRECAUTIONS
WHEN WORKING ON THIS UNIT.
1. Store and transport all complementary metal-oxide
semiconductor (CMOS) devices in conductive material
so that all exposed leads are shorted together. Do not
insert CMOS devices into conventional plastic "snow"
trays used for storage and transportation of other semiconductor devices.
1. Turn off the radio.
2. Remove the battery (see Figure 40-4).
a. Hold the radio such that the battery is tilted
down.
b. Press down on the two battery-release levers.
c.
With the release levers pulled down, the top of
the battery will fall away from the radio.
d. Remove the battery completely from the radio.
2. Ground the working surface of the service bench to protect the CMOS device. We recommend using the
Motorola Static Protection Assembly (part number
0180386A82), which includes a wrist strap, two ground
cords, a table mat, and a floor mat.
3. Wear a conductive wrist strap in series with a 100k
resistor to ground. Replacement wrist straps that connect to the bench top covering are Motorola part
number RSX-4015.
4. Do not wear nylon clothing while handling CMOS
devices.
5. Neither insert nor remove CMOS devices with power
applied. Check all power supplies that are to be used
for testing CMOS devices to be certain that there are no
voltage transients present.
MAEPF-22524-A
6. When straightening CMOS pins, provide ground straps
for apparatus used.
7. When soldering, use a grounded soldering iron.
8. If at all possible, handle CMOS devices by the package
and not by the leads. Prior to touching the unit, touch an
electrical ground to remove any static charge that you
may have accumulated. The package and substrate
may be electrically common. If so, the reaction of a discharge to the case would cause the same damage as
touching the leads.
A. General
Since this product disassembles and reassembles
without the use of any screws, it is important for the
technician to pay particular attention to the snaps and
tabs, and how parts align with each other.
NOTE
In the disassembly/reassembly procedure, the numbers in parentheses refer to call-out numbers in the
referenced figures.
Figure 40-4.
3. Loosen the antenna by turning it in a counterclockwise direction, and remove it from the radio.
4. Remove the volume on/off knob and the channel
selector switch knob by pulling them off their
respective switch shafts.
NOTE
Both knobs slide on and off but fit very snug on their
respective switch shafts. A small flat blade screwdriver may be necessary to help pry the knobs loose.
Take care not to mar the surrounding radio surface.

and slide the chassis (switch end first) into the
front cover assembly. Check to ensure that the
orange emergency button seal slides into position freely.
NOTE
When performing the next part of this step, pay
particular attention to the O-ring near the bottom
of the radio to ensure that it does not raise up
and get pinched between the front cover clip and
the chassis.With the top of the chassis fully seated, lower the bottom of the chassis and press it
into the front cover assembly until it snaps into
place.
d. Check the emergency button again. If it
is cocked to one side, repositioning it may be
necessary.
6. Reinstall the switch knobs and antenna; the shorter
knob with the volume on/off switch, the taller knob
with the channel selector switch.
7. Reinstall the battery.
SECTION VII. MAINTENANCE
A. Introduction
This section of the manual describes preventive
maintenance, safe handling of CMOS devices, and
repair procedures and techniques. Each of these topics
provides information vital to the successful operation
and maintenance of your radio.
B. Preventive Maintenance
The HT 1000, MT 2000, MTS 2000, and MTX series
radios do not require a scheduled preventive maintenance program; however, periodic visual inspection and
cleaning is recommended.
1. Inspection
Check that the external surfaces of the radio are
clean, and that all external controls and switches
are functional. A detailed inspection of the interior
electronic circuitry is not needed or desired.
2. Cleaning
The following procedures describe the recommended cleaning agents and the methods to be used
when cleaning the external and internal surfaces of
the radio. External surfaces include the front cover,
chassis (rear cover), and battery case. These surfaces should be cleaned whenever a periodic visual
inspection reveals the presence of smudges,
grease, and/or grime. Internal surfaces should be
cleaned only when the radio is disassembled for
servicing or repair.
The only recommended agent for cleaning the
external radio surfaces is a 0.5% solution of a mild
dishwashing detergent, such as JOY®, in water. The
only factory recommended liquid for cleaning the
printed circuit boards and their components is isopropyl alcohol (70% by volume).
!
CAUTION
The effects of certain chemicals and their vapors
can have harmful results on certain plastics.
Aerosol sprays, tuner cleaners, and other chemicals should be avoided.
a. Cleaning External Plastic Surfaces
(The detergent-water solution should be applied
sparingly with a stiff, non-metallic, short-bristled
brush to work all loose dirt away from the radio.
A soft, absorbent, lintless cloth or tissue should
be used to remove the solution and dry the
radio. Make sure that no water remains
entrapped near the connectors, cracks, or
crevices.
b. Cleaning Circuit Boards and Components
Isopropyl alcohol may be applied with a stiff,
non-metallic, short-bristled brush to dislodge
embedded or caked materials located in hard-
to-reach areas. The brush stroke should direct
the dislodged material out and away from the
inside of the radio.
Alcohol is a high-wetting liquid and can carry
contamination into unwanted places if an
excessive quantity is used. Make sure that controls or tunable components are not soaked
with the liquid. Do not use high-pressure air to
hasten the drying process, since this could
cause the liquid to puddle and collect in unwanted places.
Upon completion of the cleaning process, use a
soft, absorbent, lintless cloth to dry the area. Do
not brush or apply any isopropyl alcohol to the
frame, front cover, or back cover.
NOTE
Always use a fresh supply of alcohol and a
clean container to prevent contamination by dissolved material (from previous usage).
C. Safe Handling of CMOS Devices
Complementary metal-oxide semiconductor
(CMOS) devices are used in this family of radios. While
the benefits of CMOS are many, their characteristics
make them susceptible to damage by electrostatic or
high voltage charges. Damage can be latent, resulting in
failures occurring weeks or months later. Therefore, you
must take special precautions to prevent device damage
during disassembly, troubleshooting, and repair. Handling precautions are mandatory for CMOS circuits, and
are especially important in low humidity conditions. DO
NOT attempt to disassemble the radio without first
referring to the CMOS CAUTION paragraph in the Disassembly and Reassembly section of the manual.
D. Repair Procedures and Techniques
Refer to the Disassembly and Reassembly section
of the manual for pertinent information prior to replacing
and substituting parts.
1. General
a. Parts Replacement and Substitution
Special care should be taken to be as certain
as possible that a suspected component is
actually the one at fault. This special care will
eliminate unnecessary unsoldering and removal
of parts, which could damage or weaken other
components or the printed circuit board itself.
When damaged parts are replaced, identical
parts should be used. If the identical replacement component is not locally available, check
the parts list for the proper Motorola part number and order the component from the nearest
Motorola Communications Parts office listed in
the "Replacement Parts Ordering" section of
this manual.
23
b. Rigid Circuit Boards
c.
This family of radios uses bonded, multi-layer,
printed circuit boards. Since the inner layers are
not accessible, some special considerations are
required when soldering and unsoldering components. The printed-through holes may
interconnect multiple layers of the printed circuit. Therefore, care should be exercised to
avoid pulling the plated circuit out of the hole.
On the latest version HT 1000, MT 2000,
MTS 2000, and MTX series radios, a strip connector, two female connectors and a strain relief
electrically connect the RF board with the controller board. On earlier versions of these
radios, the RF board and controller board were
connected using a jumper flex that soldered
directly to the circuit board solder pads.
When soldering near the module socket pins,
use care to avoid accidentally getting solder in
the socket. Also, be careful not to form solder
bridges between the module socket pins.
Closely examine your work for shorts due to
solder bridges. When removing modules with
metal enclosures, be sure to desolder the
enclosure ground tabs as well as the module
pins.
An interconnect kit, REX4035A, is available to
retrofit earlier version jumper-flex radios with
the later version strip connector parts. The
REX4035A kit includes the following items:
• CONNECTOR, Female (J301)
• CONNECTOR, Female (J704)
• CONNECTOR, Male
(P301/P704)
• STRAIN RELIEF
• INSTRUCTIONS
Flexible Circuits
The flexible circuits are made from a different
material than the rigid boards, and different
techniques must be used when soldering.
Excessive prolonged heat on the flexible circuit
can damage the material. Avoid excessive heat
and excessive bending. For parts replacement,
use the ST-1087 Temperature-Controlled Solder Station with a 600 or 700 degree tip, and
use small diameter solder such as ST-633. The
smaller size solder will melt faster and require
less heat being applied to the circuit.
To replace a component on a flexible circuit,
grasp the edge of the flexible circuit with seizers
(hemostats) near the part to be removed, and
pull gently. Apply the tip of the soldering iron to
the component connections while pulling with
the seizers. Do not attempt to puddle out components. Prolonged application of heat may
damage the flexible circuit.
2. Specific
During all repair procedures, heating neighboring
components can be minimized by:
•
using upper heat only.
•
using the correct size heat-focus head, approximately the same size as the carrier being
replaced.
•
keeping the heat focus head approximately 1/8”
above the printed circuit board when removing
or replacing the device.
!
CAUTION
If neighboring OMPAC components are heated above 365 degrees F. (185 degrees C.),
they will suffer die-bond delamination and
possible “popcorn” failure.

b. Jumper Flex (on radios shipped prior to 7/94)
Jumper flexes are not available.They are
replaced with connectors as described in paragraph “a” of this section. If the jumper flex
needs to be replaced, order Interconnect Kit
REX4035A. The retrofit kit includes all of the
parts required and detailed instructions on the
removal of the old jumper flex, and the installation of the new connector arrangement.
c.
RF Switch (S101):
Refer to the applicable exploded view and to
your radio's RF board (antenna contact area) to
locate the RF switch components.
NOTE
The RF switch spring and the RF switch piston
must be ordered separately.
To remove the RF switch:
(1) On VHF and UHF radios, unsolder the two
tabs of the RF switch bracket that secure
the RF switch to the RF board. On 800MHz
and 900MHz radios, use a #2 slotted
screwdriver to straighten the two tabs of the
RF switch bracket that wrap around the RF
board. Use your forefinger to hold the RF
switch bracket to the RF board while
straightening the tabs to avoid lifting the
solder tabs on the opposite end of the RF
switch bracket.
(2) Refer to Figure 40-16 and use a small heatfocus head to distribute heat over the area
occupied by the three solder tabs until the
solder softens.
3 Solder
Tabs
Figure 40-16.
(3) Carefully lift the RF switch assembly away
from the rf board. Notice that the RF switch
circuit board remains attached (soldered) to
the RF board.
(4) Using the same heat-focus head as in step
(3), unsolder the RF switch circuit board
and remove it from the RF board using
forceps.
(5) In the RF switch circuit board area, reflow
all the solder pad areas on the main RF
board such that similarly shaped pads have
uniform solder heights. Add or remove solder as required. Clean the RF board
thoroughly. Then swab on a minimum
amount of flux to each of the solder pads.
To replace the RF switch:
(1) Place the RF switch assembly on the RF
main board and gently heat. Visually
inspect to make sure no flux migrated onto
the gold plated areas of the RF switch
board. The guide pins should provide self
alignment between the two circuit boards.
Visually inspect the plastic switch housing
to ensure that it has not warped due to
overheating.
(2) While holding the RF switch bracket firmly
against the RF board:
• VHF and UHF radios - solder the two
leads of the housing to the solder pads
on the RF board.
• 800MHZ and 900MHz radios - bend the
two tabs around the side of the RF
board as close to the board edge as
possible to hold the bracket down
tightly.
(3) Insert the new RF switch spring and RF
switch piston into the RF switch assembly.
The contacts of the piston should be facing
the gold-plated pads of the RF switch
board. Once the spring and piston are
inserted into the RF switch, they will be
retained by the switch.
d. Chip Components
Use either the RLN-4062 Hot-Air Repair Station
or the Motorola 0180381B45 Repair Station for
chip component replacement. When using the
0180381B45 Repair Station, select the TJ-65
mini-thermojet hand piece. On either unit, adjust
the temperature control to 700 degrees F. (370
degrees C), and adjust the airflow to a minimum
setting. Airflow can vary due to component density.
(1) To remove a chip component, select a
hot- air hand piece and position the nozzle
of the hand piece approximately 1/8”
(0.3cm) above the component to be
removed. Begin applying the hot air. Once
the solder reflows, remove the component
using a pair of tweezers. Using solder wick
and a soldering iron or a power desoldering
station, remove the excess solder from the
pads.
(2) To replace a chip component using a
soldering iron, select the appropriate
micro-tipped soldering iron and apply fresh
solder to one of the solder pads. Using a
pair of tweezers, position the new chip
component in place while heating the fresh
solder. Once solder wicks onto the new
component, remove the heat from the solder. Heat the remaining pad with the
soldering iron and apply solder until it wicks
to the component. If necessary, touch up
the first side. All solder joints should be
smooth and shiny.
(3) To replace a chip component using hot
air, select the hot-air hand piece and reflow
the solder on the solder pads to smooth it.
Apply a drop of solder paste flux to each
pad. Using a pair of tweezers, position the
new component in place. Position the hotair hand piece approximately 1/8” (0.3cm)
above the component and begin applying
heat. Once the solder wicks to the component, remove the heat and inspect the
repair. All joints should be smooth and
shiny.
25
e. Over-Molded Pad-Array Carrier (OMPAC)
!
CAUTION
If neighboring OMPAC components are
heated above 365 degrees F. (185 degrees
C.), they will suffer die-bond delamination and
possible “popcorn” failure.
During all repair procedures, heating neighboring components can be minimized by:
•
using upper heat only.
•
using the correct size heat-focus head,
approximately the same size as the carrier
being replaced.
•
keeping the heat focus head approximately
1/8”-1/4” (0.3cm-0.6cm) above the printed
circuit board when removing or replacing
the device.
(1) To remove an OMPAC, select the R-1319
Rework Station and the appropriate heatfocus head (approximately the same size
as the OMPAC. Attach the heat-focus head
to the chimney heater. Adjust the temperature control to approximately 415 degrees F
(215 degrees C); 445 degrees F (230
degrees C) maximum. Apply the solder
paste flux around the edge of the OMPAC.
Place the circuit board in the circuit board
holder, and position the OMPAC under the
heat-focus head. Lower the vacuum tip and
attach it to the OMPAC by turning on the
vacuum pump. Lower the heat-focus head
until it is approximately 1/8”-1/4” (0.3cm0.6cm) above the carrier. Turn on the
heater and wait until the OMPAC lifts off the
circuit board. Once the part is off, grab it
with a pair of tweezers and turn off the vacuum pump. Remove the circuit board from
the R-1070’s circuit board holder.
26
CAUTION
CAUTION
All pad-array carriers in these radios, except
for the IF IC (U3), are OMPAC. Prior to use,
all OMPACs must be kept in the sealed bag
(with moisture-indicator card) as supplied by
the Motorola Parts Department. Once the
sealed bag is opened and/or the OMPAC
subjected to ambient humidity (for an
unknown amount of time or for more than 96
hours) then that OMPAC must be baked in
an oven for at least eight hours at 260
degrees F. (125 degrees C.)
!
!
The application of heat to the OMPAC
device, beginning at ambient air temperature and ending with the OMPAC
lifting from the circuit board, should
take longer than 60 seconds. If the
OMPAC lifts from the circuit board
earlier than 60 seconds:
• check the temperature control setting on the rework station, and
if OK
• lift the heat-focus head an additional 1/8” from nominal setting, and
• check the circuit board plating for
possible damage.
(2) To replace an OMPAC, the solder pads on
the board must first be cleaned of all solder
to ensure alignment of the new chip carrier.
Prepare the site by using solder wick and a
soldering iron to remove all solder from the
solder pads on the circuit board. If a power
desoldering tool is available, it can be used
instead of the solder wick. Clean the solder
pads with alcohol and a small brush. Dry
and inspect. Ensure that all solder is
removed.
Once the preparation is complete, place the
circuit board back in the circuit board holder. Add solder paste flux in the trench of the
flux block and spread it using a one-inch
putty knife. Flux the OMPAC by placing it in
the trench of the flux block. Once the flux is
applied, place the OMPAC on the circuit
board, making certain that it is oriented correctly on the board. Position the heat-focus
head over the OMPAC and lower it to
approximately 1/8”-1/4” (0.3cm-0.6cm) over
the carrier. Using the same heat setting
used to remove the OMPAC, turn on the
heater and wait for the carrier to reflow
(heating and reflow should take longer than
60 seconds).Watch the OMPAC reflow
and note that when a proper reflow has
taken place, the OMPAC will drop (usually
one side, then the other). The end result is
that both sides have reflowed, and the
OMPAC is sitting parallel to the circuit
board.
Once the carrier reflows, raise the heatfocus head and wait approximately one
minute for the part to cool. Remove the circuit board and inspect the repair. No
cleaning should be necessary.
f.
Thin Small Outline Package (TSOP)
Components
Removing and replacing a TSOP component
will be done with the R-1319, using the same
procedure used to remove and replace an
OMPAC.
Place the circuit board in the circuit board holder. Select the proper heat focus head and
attach it to the heater chimney. Position the
TSOP component under the heat-focus head.
Lower the vacuum tip and attach it to the component by turning on the vacuum pump. Lower
the focus head until it is approximately 1/8”-1/4”
(0.3cm-0.6cm) above the component. Turn on
the heater and wait until the TSOP lifts off the
circuit board.
Once the part is off, turn off the heat, grab the
part with a pair of tweezers, and turn off the
vacuum pump. Prepare the circuit board for the
new component by applying solder paste flux to
the solder pads. Position the circuit board under
the heat-focus head, lower the head to approximately 1/8”-1/4” (0.3cm-0.6cm) above the
board, and turn on the heat. When the solder
left behind on the pads reflows, turn off the heat
and raise the heat-focus head. Remove the circuit board from the holder and inspect the pads
to ensure that the solder has flattened out and
that there are no solder shorts. Clean the area
with alcohol and a small brush.
Once the preparation is complete, place the circuit board back in the circuit board holder. Add
solder paste flux to the solder pads and place
the new component on the circuit board. Position the heat-focus head over the component
and lower it to approximately 1/8”-1/4” (0.3cm0.6cm) above the carrier. Turn on the heater
and wait for the component to reflow.
Once the component reflows, raise the heatfocus head and wait approximately one minute
for the part to cool. Remove the circuit board
and inspect the repair. No cleaning should be
necessary.
g. Shields
Removing and replacing the shields will be
done with the R-1319, using the same procedure used to remove and replace TSOP and
OMPAC components.
Place the circuit board in the circuit board holder. Select the proper heat focus head and
attach it to the heater chimney. Add solder
paste flux around the base of the shield. Position the shield under the heat-focus head.
Lower the vacuum tip and attach it to the shield
by turning on the vacuum pump. Lower the
focus head until it is approximately 1/8”-1/4”
(0.3cm-0.6cm) above the shield. Turn on the
heater and wait until the shield lifts off the circuit
board. Once the shield is off, turn off the heat,
grab the part with a pair of tweezers, and turn
off the vacuum pump. Remove the circuit board
from the circuit board holder.
To replace the shield, add solder to the shield
if necessary, using a micro-tipped soldering
iron. Next, rub the soldering iron tip along the
edge of the shield to smooth out any excess
solder. Use solder wick and a soldering iron to
remove excess solder from the solder pads on
the circuit board. Place the circuit board back in
the circuit board holder. Place the shield on the
circuit board using a pair of tweezers. Position
the heat-focus head over the shield and lower it
to approximately 1/8”-1/4” (0.3cm-0.6cm) above
the shield. Turn on the heater and wait for the
solder to reflow.
Once complete, turn off the heat, raise the heatfocus head, and wait approximately one minute
for the part to cool. Remove the circuit board
and inspect the repair. No cleaning should be
necessary.
h. RF PA (U105)
The procedure for removing and replacing the
RF PA is very similar to the procedure for
removing and replacing an OMPAC or a TSOP
component. But because the the device is
large, extra heating time is required to flow the
pads. And as a result, neighboring components
(especially those on the opposite side of the circuit board) will heat, reflow, and may
inadvertently move. Be careful when performing
the following procedure.
PA Cover
Leads
Slab
Solder
Pads
Figure 40-17.
(1) Refer to Figure 40-17 for
RF PA nomenclature.
To remove the RF PA, add flux to the
leads of the device, and use a soldering
iron and pair of tweezers to heat and lift
each lead free and clear of its respective
solder pad on the circuit board. Use the
R-1319 Rework Station and the heat- focus
head designed especially for removal of the
RF PA. Attach the heat-focus head to the
chimney heater. Adjust the temperature
control to approximately 415 degrees F
27
(215 degrees C) 445 degrees F (230
degrees C) maximum. Apply solder paste
to the exposed solder pads under the PA.
Place the circuit board in the circuit board
holder, and position the RF PA under the
heat-focus head. Lower the heat-focus
head until it is approximately 1/8”-1/4”
(0.3cm-0.6cm) above the PA cover. Turn
on the heater and begin the reflow cycle.
Heating time should not be less than two
minutes.
Once the part has reflowed, before trying to
remove the PA, carefully lower the circuit
board holder as follows:
• Loosen the thumbscrew on the shaft of
the circuit board holder,
• push the spring-loaded holder down and
away from the heat-focus head, and
• retighten the thumbscrew with the holder
in the bottomed position.
Grab the PA with a large pair of tweezers
and remove it from the circuit board. Let the
circuit board cool for approximately two
minutes. Then remove the circuit board
from the circuit board holder.
(2) To replace the RF PA; if necessary, add
solder to the PA ground plane on the printed circuit board. Then clean each PA lead
28
solder pad on the circuit board to ensure
alignment of the new RF PA. Prepare the
sight by using solder wick and a soldering
iron to remove all solder from the solder
pads. Clean the solder pads with alcohol
and a small brush. Dry and inspect. Ensure
that all solder is removed.
Once the preparation is complete, place the
circuit board back in the circuit board holder. Add solder paste flux to the ground
plane and to the leads’ solder pads. Once
the flux is applied, place the new RF PA on
the circuit board, making certain that the PA
heatsink sits flush on the board. Position
the heat-focus head over the RF PA and
lower it to approximately 1/8”-1/4” (0.3cm0.6cm)) above the PA cover. Turn on the
heater and begin the reflow cycle. Heating
time should not be less than two minutes.
Once the RF PA reflows, raise the heatfocus head and wait approximately two
minute for the part to cool. Remove the circuit board and inspect the solder joint
between the slab and the ground plane. No
cleaning should be necessary. Use the soldering iron and add solder to each of the
RF PA leads and associated pads. Inspect
the lead/pad bond for opens and solder
shorts.

Note: On later version radios, P301 and P704 are physical pins, at either
end (and part of) a strip connector. They plug into counterpart jacks
(physical connectors) on the RF board and the controller board, J301 and
J704 respectively. On early version radios, P301 and P704 are solder pads at
either end of a jumper flex that solder directly to their counterpart jacks
(solder pads) on the RF board and controller board, J301 and J704
respectively.

APPENDIX
Secure Modules: NTN7279A, NTN7280A, NTN7281A, NTN7282A, and NTN7283A
for MTS 2000 Radios
NOTE
The Secure Module is NOT serviceable. The information contained in this appendix is only meant to help
determine whether a problem is due to the Secure
Module or the radio itself.
I.
INTRODUCTION
The Secure Module is designed to digitally encrypt
and decrypt voice data in Motorola’s MTS 2000 Series
Handie-Talkie™ Portable Radios. The Secure Module
uses a custom encryption integrated circuit (IC) and
an encryption key variable to perform its
encode/decode function. The encryption key variable
is loaded into the Secure Module via the radio’s universal (side) connector from a hand held key variable
loader. The encryption IC corresponds to the particular
encryption algorithm purchased. The encryption algorithms and their corresponding kit numbers are:
•
•
•
•
•

NTN7280A
NTN7281A
NTN7282A
NTN7283A
II. CIRCUIT DESCRIPTION
The Secure Module, shown in Figure 1, operates
from two power supplies. The first 5 volt supply (Vdd)
is received from the controller board through connector plug P1 pin 2. This Vdd supply is turned on and off
with the radio on/off switch. The second supply
(UNSW B+) is received from the controller board
through connector Plug P1 pin 1. UNSW B+ provides
power to the Secure Module as long as the radio battery is in place.
Key variables are loaded into the Secure Module
through connector P1 pins 13, 15, and 16. One key
variable can be stored in the module at a time. The
key variable is stored in volatile electronic memory, so
it can only remain in memory as long as the radio is
connected to a charged battery. If the battery is
removed or if the battery fails, then a capacitor will
allow the module to retain the key variable for at least
30 seconds while the battery is being replaced.
The radio’s host processor communicates with the
Secure Module on the Serial Peripheral Interface (SPI)
bus. The host processor is the master on this bus,
while the Secure Module is a slave on the bus. The
SPI bus consists of five signal lines. Refer to Table 1
for the signal information. A communications failure
between the host processor and the Secure Module
will be indicated as an “ERROR 09/10” message on
the radio display.

III. Troubleshooting Secure Operations
Refer elsewhere in this radio service manual for
disassembly and reassembly information, and refer to
the radio theory/troubleshooting manual for a general
overview of troubleshooting information and procedures. A key variable loader and oscilloscope are
needed to troubleshoot the Secure Module.
NOTE
The Secure Module itself is NOT serviceable. If the
Secure Module is found to be defective then it must
be replaced.
A. ERROR 09/10
The MTS 2000 Series Handie-Talkie™ Portable
Radio automatically performs a self test on every
power-up. Should the radio fail the self tests, the display will show “ERROR XX/XX” (where XX/XX is
alphanumeric) accompanied by a short beep. If the
display shows “ERROR 09/10” or “E09/10”, then the
radio failed the secure power-up self tests and the
host microcontroller is unable to communicate with the
Secure Module via the SPI bus. Turn off the radio,
check the battery connection, and turn the radio back
on. If the radio still does not pass the self tests, then a
problem exists with the secure operations of the radio.
Since the module is removable, a good first step
in troubleshooting secure operation is simply to
replace the suspect Secure Module with a known
52
Not Used
working module. If this does not fix the problem, then
the original module is probably not the cause of the
problem. If the new module does fix the problem, then
the original module must be replaced.
A complete procedure for troubleshooting this
error is listed below:
1. Turn the radio off, check the battery connection,
and turn the radio back on.
2. If the error condition still exists, check that a
Secure Module is installed and make sure that it is
properly connected to the controller board. To do
this, refer to the disassembly and reassembly sections of this manual.
3. Turn the radio back on.
4. If the error condition still exists and a working
secure module with the same kit number is available, replace the suspect module with the working
module.
5. If the problem persists, disassemble the radio and
check the encryption connector SPI pins (listed in
Table 1) for data transitions when the radio is
turned on and off. If activity is not seen on all five
lines, check both sides of the connector for broken
connections.
6. Troubleshoot the Controller Board.
B. Keyloading Problems
Use the following procedure to troubleshoot keyloading problems:
1. Verify that the correct Key Variable Loader (KVL)
is being used for the particular encryption algorithm present in the radio. Refer to the following
chart:
IV. SERVICE AID
A cable, Motorola kit number TDN9390A,
connects the MTS 2000 radio universal connector to
the keyloader.

Description
2. Connect the KVL to the radio via the TDN9390A
keyloader cable. Whe the cable is connected to
the radio, the radio should enter the keyloading
mode of operation, and the radio should display
“KEYLOADING” or “KEYLDG” and make a beep
tone.
3. If the radio displays “ERROR 09/10” or “E09/10”
then go to the ERROR 09/10 troubleshooting section.
4. If the radio does not go into keyloading mode,
detach and reattach the keyloader cable.
5. If there is still a problem, refer to the universal
connector illustration found in the schematic and
circuit board section of this manual, and short pins
8, 10, and 12 on the universal connector together.
If this causes the radio to go into keyloading
mode, then replace the keyloader cable.
6. If the radio still does not go into keyloading mode,
check the continuity of the the Front Cover/Display
Flex and make sure that the Flex is properly connected to the Universal Connector and to the
Controller Board.
7. If the radio does go into keyloading mode, but
after starting the keyloading process the KVL display indicates “X FAIL”, then check to see if there
are transitions on pins 13, 15, and 16 of connector
P1 on the Secure Module during a keyload.
8. If there are no transitions on any one of these
lines during a keyload, check the integrity and
continuity of the Expansion Board Connector. If it
is OK, try replacing the Controller Board.
9. If there are transitions on these lines, try replacing
the Secure Module.
10. If the KVL display indicates “X PASS” but you cannot hear a keyload verification tone, then check
the volume of the radio. If the volume is OK, troubleshoot the receive routing paths in the radio.
The radio must be partially disassembled to install
the secure module.
!
CAUTION
Anti-static precautions must be observed at all
times.
Follow the disassembly procedures in section VI,
located toward the front of this manual. Proceed
through paragraph B (Disassembly to Board Level) step
8, where the front cover has been removed and the
controls flex has been disconnected from the controller
board.
Continue through step 9a, to loosen the front
shield. Do not completely remove the front shield.
Simply raise the lower portion of the shield while the
opposite end is still connected to the top of the radio.
With the front shield raised, observe the controller
board which takes up the bottom third of the radio. On
the lower right corner of the controller board is an
empty female connector, which will be used to mate the
controller board to the secure module. Place the secure
module (component side toward controller board) over
the controller board with the secure module's male connector placed above and aligned to the female
connector on the controller board. Interlock the connectors by pressing down on the back of the the secure
module. The secure module has now been installed.
Reassemble the radio according to the reassembly
instructions in section VI, located toward the front of
this manual. Begin with paragraph E, step 5b.
C. Update Codeplug Through RSS
1. General
Once the secure module is installed, the radio's
codeplug must be reprogrammed so that the new
hardware can be used. There will also be some
secure options that the user may or may not want
to activate. Table 3, at the end of this appendix,
gives a quick reference to several properties and a
53
brief description for each parameter. Refer to the
RSS manual for general instructions in the use of
RSS.
2. Set Secure-Equipped Field
The radio must be reprogrammed to utilize the
secure module. At the RSS main menu, press F4
for the CHANGE/CREATE/VIEW menu. Press F3
for the Radio Wide Buttons, Switches, Display,
Scan, Phone screen. Press F2 for Radio Wide
Options screen. Here, press tab to reach the
Secure Equipped field. Press up/down arrow keys
to select YES.
3. Set XL IC Present Field
If the secure module has an XL IC (the Range
Extension or -XL option), the radio must be reprogrammed to show that this IC is present. While still
in the Radio Wide Options screen, press F6 to see
Secure Options. Press Tab until the XL IC Present
field is highlighted. Press up/down arrow keys to
select YES. If the secure module does not have an
XL IC, set the XL IC Present field to NO.
4. Enable Secure On Desired Channels
To actually use the secure option, Secure must be
enabled on the channels for which it is desired. A
channel can be strapped to secure-only, or clearonly, or secure/clear-selectable.
For conventional channels, proceed as follows:
Press F4 at the Main Menu to see the
CHANGE/CREATE/VIEW menu. Press F6 to see
Conventional Systems, Personalities, MDC,
Options. Press F3 to see Conventional Personalities, Options. Press F6 to see the SECURE
OPTIONS screen. Press Tab to select the
Secure/Clear Strapping field.
For trunking channels, proceed as follows: Press
F4 at the Main Menu to see the CHANGE/CREATE/VIEW menu. Press F4 to see Trunking
Systems, Personalities, Call Lists, Options screen.
Press F4 to see Trunking Personalities: Talk
Groups, Emergency Options, etc. Press Tab to
select the Strapping field. An Announcement Group
must be specified for the Strapping parameter to
appear. This selects the Announcement Group
Strapping. Press F7 to select Talk Groups. Press
Tab to select the strapping of each Talk Group.
5. Other Secure Options
There are other secure options that can be
changed on a per-channel basis, such as: Proper
Code Detection, Transmit XL, or CFB. For conventional channels, these options are found on the
same screen as Secure/Clear Strapping
(F4/F6/F3/F6). These options are XL Transmit,
Scan Holdoff Strapping, RX Modulation, and Proper
Code Detect. For trunking channels, the only
54
selectable option is Proper Code Detect. This can
be found by going to the MORE OPTIONS screen
(F9) from the screen that was used to select
secure/clear Strapping for trunking channels.
D. Secure Retrofit Tuning
After installing a secure-retrofit board into a radio,
the secure TX deviation and the secure RX discriminator level must be tuned. Follow the procedure outlined
in section III of this publication for the tuning of these
two secure-related alignments.
The TX deviation balance (compensation) does not
need to be performed as part of the secure retrofit procedure. Use the transmit deviation balance
(compensation) procedure as outlined in this appendix,
section III paragraph B, only when a complete radio
alignment is being performed with a secure board
installed.
VI. SECURE ALIGNMENT PROCEDURE
A. General
For optimum radio performance, the secure transmit deviation and the receive discriminator level must
be set. Refer to SECTION V, RADIO ALIGNMENT
PROCEDURE, for a description of the radio alignment
test setup, an RSS service menu overview, and for general radio tuning procedures. All normal radio tuning
should be performed in the proper sequence before
proceeding with secure tuning.
Note that the transmit deviation balance (compensation) tuning must be performed differently if a secure
board is installed in the radio. Follow the procedure
changes outlined below when tuning transmit deviation
balance, and complete the normal tuning. Then proceed with the additional tuning for secure TX deviation
and secure RX discriminator level tuning.
B. Transmit Deviation Balance (Compensation)
When tuning with a secure board installed, the coupling capacitor inside the RKN4035A Test Cable will
cause rolloff of the low port modulation. To fix this, the
cable should be dc coupled ("VOL" position) and an
external coupling capacitor (1.3µF or larger) must be
placed in series with the signal source input to the
AC/DC MTR.
Follow the Transmit Deviation Balance (Compensation) procedure outlined in section V paragraph G,
except change step 3 as follows:
3. Set the RTX4005B Test Box meter selector switch
to the "VOL" position, and connect the signal
source to the AC/DC MTR port thru a 1.3µF capacitor. Inject an 80 Hz tone at 100mVrms thru this
capacitor. Keep the ac voltmeter in parallel to the
AC/DC MTR input to ensure the proper input signal
level.
C. Secure TX Deviation
Transmit deviation balance compensation and
transmit deviation limit adjustments should be completed before secure deviation is adjusted. Remember to
use the new transmit deviation balance procedure outlined in paragraph B before performing the following
steps.
1. From the SERVICE menu, press F2 to select
TRANSMITTER alignment.
6. Press F6 to dekey the radio. Press F8 to program
the softpot value.
7. Press F10 to return to the TRANSMITTER menu.
D. Secure RX Discriminator Level
1. Set the RTX4005B Test Box meter selector switch
to the "MX DISC" position, and connect an ac voltmeter (capable of 1mV resolution on a 2V scale) to
the test box AC/DC meter port.
2. Press F8 to select the SECURE TX DEV softpot.
2. From the SERVICE menu, press F3 to select
RECEIVER alignment.
3. Press F6 to key the radio on the test frequency.
The screen will indicate that the radio is transmitting.
3. Press F8 to select the SECURE DISCRIMINATOR
LEVEL softpot. The screen will indicate the receive
test frequency to be used.
4. Measure the secure deviation on your service monitor.
4. Set the RF test generator to the receive test frequency. Set the RF level at the radio standard
antenna port to 1mV (-47dBm) modulated with 3.0
kHz FM deviation of a 1 kHz tone.
5. Use the up/down arrow keys to adjust the secure
deviation per Table 2.
Table 2. Secure Deviation
Channel Spacing (KHz)
Secure Deviation (KHz)
5. Use the UP/DOWN arrow keys to obtain a discriminator level between 206 - 218mVrms (target value
of 212 mVrms) observed on the ac volt-meter.
