Transmit Power Selection Mode
This feature permits selection of the transmitting power level to high
or low. (FRS channels 1-7 operate on low power.) Using low power,
the unit will have a lower transmit range, but battery life will be in-
creased.
NOTE:
You will find that for the majority of your needs, the low-power
setting will provide adequate communications on all channels;
there should seldom be any need to use high power, except in
situations where you need absolute maximum range. Using low
power will greatly extend battery life. We suggest you experi-
ment with switching between low and high power. However,
we do recommend that you
not change this setting unless it
proves to be necessary in your particular situation.
To access the transmitter power selection function:
- From GMRS/FRS standby mode, press the MODE Button three times
until the Po HI or Lo indication appears with a flashing HI or LO indica-
tion on the display.
- Press the Up or Down button to toggle between the High and Low se-
lections.
- Press the PTT button momentarily to confirm selection.
VOX Selection Mode
This option enables you to have hands-free conversation. Your voice or
nearby sound is detected and the radio transmits without the need to
press the PTT button.
To set radio for VOX operation:
- From GMRS/FRS standby mode, press the MODE button 4 times
until the VOX icon flashes on the display.
- Press the Up or Down button to select VOX On (if oF appears flash-
ing) and the 1-5 VOX level sensitivity.
- Press the PTT button momentarily to confirm the VOX selection.
- The VOX icon will appear steady on the LCD display.
VOX can be turned off by selecting oF as the setting.
