Squelch (hiss reduction)
The "Squelch" feature will reduce the distracting radio hiss or static noise. You can choose between five squelch levels by
pressing the (+) button (A:11) or (–) button (A:12). A higher squelch level will further reduce the noise, but will also reduce
your range of reception. To switch this function off, press the (–) button for two seconds. Press the (+) button to switch this
function back on.
Sub channel (selective squelch)
The Sub channel feature can be used to set up multiple private groups within a single channel. When the sub channel
feature is active, an inaudible code will be transmitted with the speech and only the receivers with the same sub channel
setting will hear the transmission. However, if anybody is transmitting on the channel, all sub-channels will be busy during
that time. If the sub channel feature is switched off, all communication on a channel will be heard. Press the (+) button
(A:11) or (–) button (A:12) to select the sub channel. The LiteCom Plus headset supports Continuous Tone Coded Squelch
System (CTCSS) and Digital Coded System (DCS) for a total of 121 frequencies/codes (see table below for sub channel #
and the associated tone/code). To switch this function off press the (–) button when sub channel 1 is selected, or press the
(+) button when channel 121 is selected. Press the (+) button to switch this function back on.
