default value of 9, or any user level between 1 and 16, can be selected using ProGrammer software. The
user can change this setting either of two ways from the front panel keys.

signal to open squelch, and a value of 1 is open squelch.
When the squelch adjust feature is activated, Channel Guard, T99 decode, and Scan are
