NOTE: To communicate with other GMRS/FRS units, they must be
switched to the same channel and CTCSS subcode. To commu-
nicate with other GMRS units that do not have subcodes, switch
your unit to the same channel with the subcode set to oF.
The CTCSS subcodes do not prevent others from hearing your
transmission. This will only allow you to ignore all traffic on a
given channel not using the same subcode.
Transmit Power Selection Mode (GMRS Channels Only)
This feature permits selection of the transmitting power level to high
or low when using channels 1-7 and 15-22. Using low power, the unit
will have a lower transmit range, but battery life will be increased.
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.
To access the transmitter power selection function:
- From GMRS standby mode, press the MODE Button 3 times until the
Po indication appears flashing on the display with a steady HI or LO
indication.
- Press the Up or Down button to toggle between the High and Low se-
lections.
- Press the PTT button to confirm selection.
The display will indicate the current setting in standby mode.
