ON/OFF Switch/Volume Control
The ON/OFF SWITCH/VOLUME CONTROL
is a combined single control located on the
top of the alert monitor as shown above. Turning the control knob a few degrees in a clockwise direction applies power to the receiver,
and an audio beep is sounded to indicate that
the alert monitor is turned on. As the control is
rotated in a clockwise direction, the volume
level of any received message and alert tone
is increased. Rotating the control in the opposite (counterclockwise) direction reduces the
audio level, and turns the alert monitor off.

Minitor TIC Book Page 5 Friday, January 9, 1998 8:10 AM
Audible/Visual Alert Indicators
When your alert monitor is initially turned on,
both the red and amber LEDs on the control
panel light and an alert tone is sounded until
the decoder circuit power-up is complete.
Thereafter, whenever a properly encoded
message is received, the red LED flashes and
an audio alert is sounded. If the battery voltage falls below the level required for reliable
operation, a low battery pulse tone sounds
and the red LED flashes. Following any subsequent audio message, the momentary low
battery pulse tone is repeated until the batteries are replaced.
If the function switch is set to a vibrate position, just the red LED flashes to indicate a low
battery state.
Function Switch
According to the specific model ordered, the
function switch will be configured to 2, 3, or 4
positions. Different function modes (monitor/
selective call, scan, etc.), can be configured
for any position of the switch.
Channel Monitoring
When the function switch is set to a monitor
position, all voice communications on the
selected channel is heard through the
speaker. When monitoring channel 1 or 2, all
ordered alert options are functional.
Reset Button
After receipt of a properly coded message
and after completion of that message, the
alert monitor reverts to carrier squelch monitoring. Press the reset button to return your
alert monitor to the standby mode.

External Speaker Jack
When the alert monitor is used in high-noise
environments or when privacy is needed, an
optional Motorola approved lapel speaker or
earpiece can be connected to the external
accessory jack located on the top control
panel. The jack is fitted with a protective plug.
NOTE
To prevent entry of dust and moisture, the plug should be inserted
whenever the external accessory
jack is not being used.
Belt Clip Feature
An integral part of the clip on the back of your
monitor is a security hook. This hook is
intended to allow easy removal of the alert
monitor, while at the same time preventing the
unit from being pulled off your belt.
Scan (Two-Frequency Models Only)
All alert monitors that are equipped with two
frequencies are capable of scanning the two
channels for selective call or monitoring purposes. The scan feature may be programmed
for either priority scan or non-priority scan.
This feature is factory installed as priority
scan. Non-priority scan is field programmable.
FACTORY OPTIONS
The options that are described in the paragraphs that follow are limited to those options
that affect the operation and/or functional
characteristics of your alert monitor. For a
complete list of available options, contact your
Motorola sales representative or authorized
paging system dealer.

Fixed-Alert, Audio-Only Volume Control
When this option is installed, the alert tone is
factory preset (non-adjustable) at the maximum volume level. Turning the volume control
varies only the voice message volume level.
NOTE
Use of audio accessories is not recommended with this option.
Time-Out Auto Reset
This feature allows the alert monitor to be
automatically reset after a predetermined
amount of time. This places the alert monitor
back in standby mode to help conserve battery power.
FIELD INSTALLED OPTIONS
Several alert monitor field programmable
options are available to include the following:
•
•
•
•
•
Non Priority Scan
Alert Duration
Priority Alert
On/Off Duty
Reset Options
- Carrier Reset
- Delayed N Carrier Reset
- Manual Reset
• Push-To-Listen
Contact a Motorola authorized paging system
dealer or call 1-800-548-9954 for the addition
of these features.

OPERATION
Perform the following steps to condition your
alert monitor for operation:
1. Set the FUNCTION switch to a tone-alert
position.
2. Rotate the ON-OFF SWITCH/VOLUME
CONTROL clockwise to turn on the alert
monitor. Eight short beep sounds occur
and both LEDs light, indicating that power
is applied.
3. Set the FUNCTION switch to a monitor
position.
4. Listen for a transmission and adjust the volume control to a comfortable listening level.
5. If no transmission is heard, hold down the
RESET button and adjust the background
noise to a comfortable listening level. It may
be necessary to readjust the volume when
a voice signal is present.
6. Set the FUNCTION switch to the desired
operating mode, i.e., selective call tone,
selective call vibrate, monitor, scan, etc.
7. Turn off the monitor by rotating the ON-OFF
SWITCH/VOLUME CONTROL counterclockwise until a click is heard and the
mechanical stop is reached.
SCAN OPERATION
Priority Scan
If the alert monitor is programmed for priority
scan, the frequency programmed as F1 is
designated as the priority channel. If there is
no traffic on F1, the alert monitor alternately
listens to F1 and F2 until a transmission is
detected. If a transmission is detected on F1,
the alert monitor stays on that channel until
the transmission ceases. The alert monitor
only decodes tones on the F1 channel. No
tones are decoded on the F2 channel.
8
Minitor TIC Book Page 9 Friday, January 9, 1998 8:10 AM
If the alert monitor detects a transmission on
F2, it stops on F2 then listens for transmissions on F1. Scanback time is programmable
and can be set to 0.5, 1, or 2-second increments. If a transmission is detected on F1, the
alert monitor switches to F1 cutting off any
transmission on F2. When switching from F2
to F1, the alert monitor listens for any tones
and alerts if the proper tones are detected. It
should be noted that the detection of tones is
very dependent on the duration of the tone
sent over the air. To ensure reliable alerting, it
is recommended that this feature only be
used when the first tone duration transmitted
is one second or more.
During the scan mode, the amber LED blinks
fast to indicate transmission on F1 and at a
slower rate for transmission on F2.
Non-priority Scan
In the non-priority scan mode, the alert monitor alternately listens on F1 and F2 for any
transmission. A transmission on either channel causes the alert monitor to stop on that
channel until the signal disappears. In nonpriority scan, the alert monitor decodes tones
on either F1 or F2 provided the alert monitor
has listened to the appropriate channel at the
correct time. However, it should be noted that
if the alert monitor is listening to traffic on F2
and an alert is transmitted on F1, the alert
monitor will not hear that signal until the transmission on F2 is finished. Therefore, an emergency alert could be missed if the alert
monitor is listening to traffic on one channel
with tones being sent out on the other channel.

BATTERY LIFE
Battery life depends upon the number of calls
received, length of each call, capacity and
charge of the battery, and the mode of operation.
When the battery voltage drops below an
acceptable level, the red LED flashes and a
low battery pulse tone is sounded. The LED
continues to flash and voice communication
deteriorates until the batteries are replaced. If
the unit is recharged without being turned off,
the low battery alert signal will continue until
the RESET button is pressed.
REPAIR AND MAINTENANCE
Your alert monitor, properly handled, will provide quality service for years. However,
should it ever require service, call 1-800-5489954 for instructions.
ACCESSORIES
Motorola offers several accessories to
increase communications efficiently and provide many unique benefits. Consult your
Motorola sales representative for a complete
list of accessories, prices, and applications.
