- From GMRS standby mode, press the Mode Button twice; a flashing
oF or sub-channel number is displayed. If oF is displayed, press the
Up or Down button to enable the CTCSS mode; the CTC icon will
appear steady on the display with the flashing sub-channel number.
- Then press the Up or Down button to select the desired sub-channel
for use.
- Press the Power On/Off button momentarily to confirm selection.
The CTCSS mode can be turned off by selecting the oF icon as the setting.
NOTE: To communicate with other GMRS units, they must be switched to
the same channel and CTCSS subcode. To communicate 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.
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 and hold the SCAN button until
the VOX icon appears on the display.
- Press the Up or Down button to select VOX sensitivity from 1 to 5.
- Momentarily press the PTT button to confirm the VOX selection.
VOX can be turned off by pressing the SCAN button for 2 seconds.
