SAFETY INFORMATION
The Federal Communications Commission (FCC),
with its action in General Docket 79-144, March 13,
1985, has adopted a safety standard for the human
exposure to radio frequency (RF) electromagnetic
energy emitted by FCC regulated equipment. Proper
operation of this radio will result in user exposure far
below the Occupational Safety and Health Act and
Federal Communication Commission limits.
DO NOT hold the radio in such a manner that the
antenna is close to, or touching, exposed parts of the
body -- especially the eyes or face --while the radio is
transmitting.
DO NOT operate the radio near unshielded electrical
blasting caps or in an explosive atmosphere, unless it is
a type specifically designed and qualified for such use.
DO NOT operate the radio unless the antenna
connector is secure and any open connectors are
properly terminated.
DO NOT allow children to operate transmitter-
equipped radio equipment.
This device complies with Part 15 of the FCC
rules. Operation is subject to the condition that this
device does not cause harmful interference.

BATTERY CHARGING AND CARE
Do not dispose of the battery pack in fire - it may
explode, causing injury or death.
Do not replace the battery in hazardous atmosphere
locations.
Do not carry battery loose in your pocket or purse.
Do not attempt to repair battery.
The product you have purchased
contains a rechargeable battery. The
battery is recyclable. At the end of its
useful life under various state and local
laws it may be illegal to dispose of this
battery into the municipal waste stream.
Check with your local solid waste officials
for details concerning recycling options or
proper disposal in your area. Call Toll Free 1-800-8-
BATTERY for information and/or procedures for
returning rechargeable batteries in your state.
Your radio comes supplied with one 7.5 volt 1100
mAh Ni-Cd battery pack, which can be recharged from
500 to 1000 times before requiring replacement. The
actual number of charge / recharge cycles vary
depending upon usage. We recommend that the battery
g

8
be charged 14 to 16 hours on the first charge cycle and
then in accordance with the charger model instructions
thereafter.
To remove the battery pack, push up on the battery
latch and slide the battery pack to the right. To replace
the battery, align the battery on the track and slide to the
left until a click is heard, indicating the battery is correctly
installed.
If the battery is to be charged on the radio, ensure
that the power switch on the radio is in the off position
before charging. Failing to turn the power switch to off
during the charge cycle will result in a less than full
charge condition, which will noticeably reduce the
operating time between charges!
Normal battery operation time is 8 hours. This may
vary depending upon how much the receiver audio is
present and how much you transmit. The actual time
may vary from day to day depending upon operational
requirements.
FOR BEST PERFORMANCE
1. Charge battery to full capacity, 14 hours at the
standard C/10 rate (capacity X .10). For "rapid"
chargers, allow additional time (2-3 hours) for
"topping off" the charge after it switches from "fast"
to "slow".
2. Use the battery soon and use as much of the battery
capacity as possible or practical. A battery that is
charged and discharged completely will maintain the

9
longest running time capacity. Also, several
charge/discharge cycles are recommended to bring
a new battery up to its rated capacity.
3. Store and charge the batteries at room temperature
65°F to 75°F. Batteries that have been stored for
over a month should be recharged before putting into
service due to chemical self-discharge which occurs
at a rate of approximately 1% per day. Do not charge
cold batteries (40°F or below).
4. Reduced capacity or "memory effect" may result
from repeated identical shallow discharge/full
recharge cycles. If such a condition is suspected, run
the battery until the instrumentation loses all power,
then fully recharge and discharge again. Repeat this
cycle 3-4 times.
EXTENDED OPERATIONS
When operating in "Fringe Areas" at some distance
from the System, the other party may not receive your
transmission clearly. Also you may notice that the
background noise will increase on received signals.
Moving to higher ground or moving closer to the System
will help alleviate these problems. If moving closer to the
System is not practical, communication may be improved
by moving away from shielding structures. If you are in a
building interior, move closer to a window (preferably one
generally in the direction of the System). At 800 MHz the
wave length is very short, sometimes moving a few
inches to a few feet can make significant signal strength
changes. Finding the best location can also be done

10
while listening to the background noise while moving
about; attempt to find a spot where the background noise
is reduced to a minimum or eliminated entirely. This may
make the difference from not being heard, to being heard
loud and clear when operating in the fringe areas of your
System coverage.
The fringe distance will vary greatly from plains
areas, hilly terrain and mountain top sites.
FCC LICENSING
This unit may or may not require a specific FCC
license to operate. The FCC requires all transmitters in
the conventional and some Trunked Systems to be
licensed by the Federal Communications Commission.
Some Trunked operations now are exempt from
individual licensing requirements but must be operated in
a licensed System.
Consult your dealer regarding specific licensing
information, or contact the Federal Communications
Commission.
For more information regarding the FCC license
application (Form 571), call 717-337-1212 for additional
information or contact the FCC District Office nearest
your location.
TRANSCEIVER SERVICE
There are no user serviceable components inside
the radio. Altering the internal components or

11
adjustments may result in illegal emissions, including off-
frequency operation, or damage to the radio.
Should an UNLOCK condition be shown in the LCD
display, or the LCD fails to display information, or all
icons and display segments are shown, turn the
ON/OFF/VOLUME control OFF then ON to reset the
microprocessor. Ensure that the battery is fully charged
and check that the antenna is securely tightened.
If the unit still fails to operate properly, refer to an
Authorized Service Center for servicing.

INTRODUCTION
The Monogram Series EDACS Trunking Portable
Radio provides reliable trunked communication in the
800 MHz band. Advanced Dual Format technology
allows the radio to operate within the EDACS Trunked
system and the GE-MARC Trunked system. The radio
will also operate in a Conventional system.
The unit is lightweight and easy to carry. A backlit
alpha-numeric display provides clear visibility for night-
time operation.
This manual provides instructions for operating in
either of the 3 systems (EDACS, GE-MARC and
Conventional). A separate section is provided for each
System (EDACS, GE-MARC and Conventional), with a
complete set of instructions for operating the radio within
that system. The DESCRIPTION section which follows
and the Battery information at the back of the manual, is
applicable to all users.
This radio allows the operator to switch between an
EDACS system, a GE-MARC system and a
Conventional system. Special attention should be
given to the system selected and the operating
characteristics of the radio working within that
system.
