✔ What is CTCSS (Continuous Tone Coded Squelch System)
GROUP MODE ?
CTCSS (Continuous Tone Coded Squelch System) GROUP
MODE allows communication with silent stand by. Only signals
containing a specific group code can open the squelch.
This conveniently eliminates unwanted audio and is useful in
group activities or security related activities where unwanted out-
put can be a problem. Note that CTCSS group mode is not pri-
vate—anyone can receive your calls.

The IC-4088SR is equipped with 38 tone codes for CTCSS
GROUP MODE use. Selecting a code applies it to all 8 operating
channels. Each push of [PTT] superimposes your group code over
your transmit signal; and, only signals containing the same code
can open your squelch. To temporarily hear all signals (including
noise) push and hold [MODE]. Do not use CTCSS GROUP MODE
if you want to be able to hear signals on all channels.
