Signalling Squelch
This feature can be enabled/disabled by your dealer. If the feature is enabled, the preset DTMF/2-Tone
/5-Tone will control repeater mute/unmute. The repeater will not unmute until valid signalling is received.
CTCSS/CDCSS
Set up talkgroups/users with unique CTCSS/CDCSS to prevent unwanted conversations on the same
frequency. If CTCSS/CDCSS is set on current channel, a CTCSS/CDCSS match will be required on an
incoming call. If not set, the radio unmutes to all calls within the communication range on current channel.
Your dealer may preset CTCSS/CDCSS on certain channels.
Note: This feature does not mean that your conversation will not be heard by others.
Time-out Timer (TOT)
The feature allows for efficient use of channels by limiting the maximum time of each transmission. It
protects the radio from damage caused by long time transmission. Once a continuous transmission
exceeds the preset time (15～1200s programmable), the transmission will be automatically terminated
and alert tone will be heard. The alert tone ceases upon the release of the PTT.

Squelch levels from 0 to 9 are selectable via the programming software.
