CTCSS filters out unwanted transmissions without the same coded squelch
tone). To change the CTCSS Sub-channel,
- From the FRS standby mode, press the MODE Button twice; the sub-
channel number will flash as it 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 with the Up or
Down button.
NOTE: To communicate with other FRS units, they must be switched to
the same channel and CTCSS subcode. To communicate with other
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.

HI or Lo indication on the display.
- Press the Up or Down button to toggle between the High and Low se-
lections.
- Momentarily press the Power Button to confirm selection.
The display will indicate the current setting in standby mode.
