1 Precautions
Follow these safety, ESD, and servicing precautions to prevent personal injury and equipment damage.
1-1 Safety Precautions
1. Be sure that all built-in protective devices are
in place. Restore any missing protective
shields.
2. Make sure there are no cabinet openings
through which people- particularly childrenmight insert fingers or objects and contact
moving parts or dangerous voltages.
3. When re-installing chassis and assemblies, be
sure to restore all protective devices, including
control knobs and compartment covers.
4. Design Alteration Warning:
Never alter or add to the mechanical or
electrical design of this equipment, such as
auxiliary connectors, etc. Such alterations and
modifications will void the manufacturer's
warranty.

7. Product Safety Notice:
Some electrical and mechanical parts have
special safety-related characteristics which
might not be obvious from visual inspection.
These safety features and the protection they
provide could be lost if a replacement
component differs from the original. This
holds true, even though the replacement may
be rated for higher voltage, wattage, etc.
8. Components critical for safety are indicated in
the parts list with symbols
. Use only
replacement components that have the same
ratings, especially for flame resistance and
dielectric specifications. A replacement part
that does not have the same safety
characteristics as the original may create
shock, fire, or other safety hazards.
Components, parts, and wiring that appear to
have overheated or are otherwise damaged
should be replaced with parts which meet the
original specifications. Always determine the
cause of damage or overheating, and correct
any potential hazards.
6. Observe the original lead dress, especially near
sharp edges, AC, and high voltage power
supplies. Always inspect for pinched, out-ofplace, or frayed wiring. Do not change the
spacing between components and the printed
circuit board.

1-1
Precautions
1-2 ESD Precautions
Certain semiconductor devices can be easily damaged by static electricity. Such components are commonly
called "Electrostatically Sensitive (ES) Devices", or ESDs. Examples of typical ESDs are: integrated circuits,
some field effect transistors, and semiconductor "chip" components.
The techniques outlined below should be followed to help reduce the incidence of component damage
caused by static electricity.
CAUTION: Be sure no power is applied to the chassis or circuit, and observe all other safety precautions.
1. Immediately before handling a semiconductor
component or semiconductor-equipped
assembly, drain off any electrostatic charge on
your body by touching a known earth ground.
Alternatively, employ a commercially
available wrist strap device, which should be
removed for your personal safety reasons prior to
applying power to the unit under test.
2. After removing an electrical assembly
equipped with ESDs, place the assembly on a
conductive surface, such as aluminum or
copper foil, or conductive foam, to prevent
electrostatic charge buildup in the vicinity of
the assembly.
3. Use only a grounded-tip soldering iron to
solder or desolder ESDs.
4. Use only an "anti-static" solder removal device.
Some solder removal devices not classified as
"anti-static" can generate electrical charges
sufficient to damage ESDs.
6. Do not remove a replacement ESD from its
protective packaging until immediately before
installing it. Most replacement ESDs are
packaged with all leads shorted together by
conductive foam, aluminum foil, or a
comparable conductive material.
7. Immediately before removing the protective
shorting material from the leads of a
replacement ESD, touch the protective material
to the chassis or circuit assembly into which
the device will be installed.
8. Maintain continuous electrical contact between
the ESD and the assembly into which it will be
installed, until completely plugged or soldered
into the circuit.
9. Minimize bodily motions when handling
unpackaged replacement ESDs. Normal
motions, such as the brushing together of
clothing fabric and lifting one's foot from a
carpeted floor, can generate static electricity
sufficient to damage an ESD.
5. Do not use Freon-propelled chemicals. When
sprayed, these can generate electrical charges
sufficient to damage ESDs.
1-3 Lithium Battery Precautions
1. Exercise caution when replacing a Lithium
battery. There could be a danger of explosion
and subsequent operator injury and/or
equipment damage if incorrectly installed.
3. Lithium batteries contain toxic substances and
should not be opened, crushed, or burned for
disposal.
2. Be sure to replace the battery with the same or
equivalent type recommended by the
manufacturer.

5-2-7 Operation Panel Control
Communication
5-2-9 CIS Input Processor
The Operation Panel is controlled by the Port 1,
Port2, and Port 5 registers.
Port 1 (E2H) is a 4-bit general output port for LCD
display data.
This port can be configured for normal data (P1.4P1.7) or alternately as internal MODEM V.24
interface output signals (P1.0-P1.3).
Port 2 (E4H) is an 8-bit port with both input and
I/O pins.
P2.0-P2.3 are input ports for OPE key scan data,
and P2.6-P2.7 are not used for SF150T.
Port 5 (EAH) is an 8-bit port with both output and
I/O pins.
P5.0 and P5.4 are used for LED control and LCD
enable.
To process the B/W input signal, maximum (+Vref)
and minimum (-Vref) values of the CIS input signal
are adjusted by calibrating KS16118 in the high state
for maximum level, and setting them to earth for
minimum level.
Shading correction uses a multiplier composed of a
9-bit sequential adder for simple H/W Logic.
5-2-10 CIS Driver
The CIS driver clock (CLK1) frequency is 250 kHz.
A 75% low duty cycle lengthens the charging time.
A start signal (SI) is provided every 10 ms to
match the line scanning time.
Actual image signal (VIN) is provided in less than
6.8 ms, based on A4 paper size using the 250 kHz
clock.
5-2-8 Image Sensor
The shading wave is formed by scanning the white
roller prior to a document.
The slice level is determined by the shading wave,
and compensates for shading distortion according
to the CIS characteristics.
The wave format from the CIS is converted into a 6
bit digital value in the KS16118 image processor,
and processed in B/W or intermediate mode.

5-2-14 Reset
This facsimile machine perform sending, receving,
and printing functions utilising a single 24 volt
motor with a 120 ohm winding resistance.
Four drive strobe pulses operate the motor.
To initialize the chipÕs internal logic, the reset
input (/RESET) must be held to 0 Volt for at least
22 CPU clocks. During this time, Vdd must be
greater than 3 Volt.
The watchdog timer can also invoke a system
reset.
When the reset input is released, the reset
condition continues for about 209.7 ms.
While the KS16118 is in this state, 0 Volt is applied
to the /RSTOUT pin.

5-2-13 Serial communication Signals
The KS16118 have two full-duplex serial
communication port.
One port is used for I-LIU communication on LIU
PBA, and is a standart UART (Universal
Asynchronous Receiver/Transmitter).
Another port, not used, may be configured for
UART or SRT (Synchronous
Receiver/Transmitter) operation.
[ +5V Power Monitoring ]
If 5 volt power to MX93000AFCÕs pin 6 (VPOW)
drops to between 4.6V and 4.4V (typically 4.5V),
power failure is indicated and the output of
MX93000AFCÕs pin 5 (/POWB) will go `lowÕ(GND5).
This causes the KS16118 to become active (low=reset).
The KS16118 reset causes the /REST0 terminal to be
reset.
5-3 Memory
System memory consists of 128 kB EP-ROM and 32 kB SRAM. All of SRAM is backed up.
ROM and SRAM are selected by chip select lines, and data is accessed by the units position of the byte.
ROM has two banks. One Bank is as low bank that address range is 0100H-FFFFH.
Another bank is as high bank 10000H-1FFFFH. ROMÕs bank is selected port 0 (bit 0) of the KS16118.
5V power is applied to SRAM through VB. This model facsimile machine uses a Lithium battery.
A 1 kohm resistor in series with the positive battery terminal is for battery protection.

from KS16118.
Memory interface sends and receives data to the
compressed voice data to and from DRAM to play
back and record voice data.
DSP communicates with host KS16118 through host
interface.
The signal stored in DRAM is decomressed in DSP
and enters into MX93000AFC.
Input signal is converted to D/A again and is
amplified by LIU-DRV amplifier and comes into
LOUT terminal through or comes into terminal
after being attanuated by ATT (Electronic Volume)
or SPK-DRV.
5-5-2 Recording Path
The voltage is supplied with MIC as using the
MX93000AFC's Vref Voltage (2.25V), and the voltage
entering into MIC is trasmitted to electric signal and
enters into MX93000AFC's MIC terminal.
Input signal is amplified by MX93000AFC's ALC
until maximum 26dB (Max. 3VP-P) according to
signal size.
The signal enters into PCM CODEC that converts to
D/A and compresses in the DSP Chip and stores in
DRAM.
SF150T
5-5-4 Voice Backup
+5V is supplied for DSP or voice memory through
VBT when power is on.
When power is off, +5V is supplied from the 9V
backup battery.
When supply voltage is "ON", U9(5V Voltage
Regulator) makes 5V Supply Voltage.
The signal is supplied with DSP or DRAM and it
caused that the data is protected.
When supply voltage is "OFF", U9 makes 5V Voltage
as using the 9V Battery.
And then the voltage is used to "backup supply
voltage" in DSP or DRAM.
If the supply voltage were "OFF" as using the full
charged 9V Battery, voice data is usually protected
for twenty hours.

¥ The ring frequency discriminator of U201
assures that only signals with a frequency
between 13Hz and 70Hz are regarded as valid
ring signals.
¥ When a valid ring signal is present for at least
