The CTCSS mode can be turned off by selecting the oF icon as the setting.
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/FRS 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
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.
