13.7 SQUELCH ADJUST In the conventional mode of operation, the squelch can be re-adjusted in the MENU selection mode or 
from a front panel key on the keypad that has been pre-programmed using ProGrammer™ software. A 
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. 
A value of 16 requires a strong signal to open squelch, a value of 2 requires a very weak 
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 
disabled. When the squelch adjust feature is exited, Channel Guard, T99 decode, and Scan 
are restored to their previous states.
