programming performed by your dealer when the radio was set up, not to
any programming that you can perform. If a feature is not controlled by a
front panel option switch, it is fixed in the mode set by dealer program-
ming or not available. If you require additional information on the opera-
tion of a feature, contact your dealer.
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 you 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. If the proceed tone is used, wait for that
tone to sound before speaking (see description on page 24).
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.
