you will not hear background noise. To manually deactivate the squelch, press and hold the

weak signal.

Quiet Talk(CTCSS) and Digital Quiet Talk(DCS)
Some channels may have pre-programmed Subtones ( CTCSS / DCS ) .
The CTCSS / DCS tone is sub-audible tones that allow you to ignore (not hear) calls from other
parties who are using the same channel.
When you receive a signal that has a different tone from the one set in the transceiver , do not
hear the signal. Similarly , the transmitted signals will be heard only by parties whose CTCSS /
DCS set to correspond to the transceiver .
In practice, if others are talking on the same your channel, the CTCSS/DCS allows you to hear
only the broadcaster using the same CTCSS/DCS .
Note: Although using channels set up with CTCSS/DCS tones re- lieves you from listening to
unwanted calls, it does not mean your calls will be private.
