radio was set up, not to any programming that a user
can perform. If a feature is controlled by a front panel
option switch and that switch is not available, it is
probably not available.
An exception is Keypad Programming which can
allow the user to reprogram several conventional
channel parameters. Refer to Section 5.16 on page 35
for more information.
7.3 SPEAKING INTO MICROPHONE
For best results, hold the microphone about 1-2
inches from your mouth and speak at a normal conver-
sational level. Do not shout since it distorts your voice
and does not increase range. Make sure that the PTT
(push-to-talk) switch is pressed before you begin to
speak and released as soon as the message is complete.
7.4 OPERATION AT EXTENDED RANGE
When approaching the limits of radio range, the
other party may not be able to hear your transmissions
and there may be an increase in background noise
when messages are received. You may still be out of
range even though you can hear a message. The reason
for this is that the signal you are receiving is usually
transmitted at a higher power level than the one trans-
mitted by your radio. Communication may be
improved by moving to higher ground or away from
shielding objects such as tall buildings or hills.
7.5 PREVENTING BATTERY DISCHARGE
In the standby mode (power on, not transmitting),
radio power consumption is relatively low. Therefore,
you can probably leave the radio on for one or two
days without operating the vehicle and the battery
should not become seriously discharged. However, if
the outdoor temperature is low enough to significantly
decrease battery capacity, the radio should be turned
off when not in use.
Since power consumption is significantly higher
when transmitting, it is good practice to have the
vehicle running while transmitting. This ensures that
optimum power is being delivered to the radio and that
the battery does not become discharged.
7.6 LICENSING
A government license is usually required to
operate this radio on the air.
7.7 RADIO SERVICE
If “UNPROGRAMD” is displayed, the cause
could be any of the following:
• An unprogrammed channel is selected. Select a
programmed channel.
• The selected channel is programmed for an option
that is not installed or an error in programming was
detected. Contact your system operator for service.
If no characters or all characters appear in the
display, the viewing angle may be improperly
adjusted. Refer to Section 3.3 on page 15 for more
information.
If some other problem is occurring, turn power
off and then on again to reset the control logic. Also
make sure that the controls are properly set and that
the power, external speaker, and accessory cables (if
used) are securely plugged into the back of the
radio.
If the radio is completely inoperative, check the
power cable fuse that is usually located near the
vehicle battery. If it is blown, remedy the cause if
possible and replace it with the same type (15A). If the
radio still does not operate properly, return it to your
system operator for service.
NOTE: There are no user-serviceable components in
the radio. Altering internal adjustments can cause
illegal emissions, void the warranty, and result in
improper operation that can seriously damage the
radio.
