2-B Selecting the Group Code (CTCSS)
The Continuous Tone Coded Squelch System (CTCSS) allows you
to ignore (not hear) unwanted calls from other persons who are
using the same channel. It provides communication with silent
standby since you will only receive calls from group members using
the same group code. The unit is equipped with 38 group codes.
The factory preset is “0” (OFF).
