If you require additional information on the operation of a feature,
contact your system operator. If the Keypad Programming option switch
is available, you can reprogram some conventional channel parameters.
Refer to “Keypad Programming” on page 38 for more information.
Speaking Into Microphone
For best results, hold the microphone about 1-2 inches from your
mouth and speak at a normal conversational 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.
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 back-
ground 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 transmitted by your transceiver. Communication may be improved by
moving to higher ground or away from shielding objects such as tall
buildings or hills.
Preventing Battery Discharge
In the standby mode (power on, not transmitting), transceiver power
consumption is relatively low. Therefore, you can probably leave the
transceiver 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
transceiver 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 transceiver and that
the battery does not become discharged.
