To Change Squelch Modes
Carrier squelch (CSQ). Tone Private-Line (PL) and Digital
Private-Line (DPL) operations are available on a per channel basis. As an option,
Signaling squelch (SelCall) operation is available on a per
channel basis.
You can override the default receive squelch mode for the
channel temporarily.
To override squelch mode:
1.
Press to change between CSQ, Coded (PL/DPL) and Signaling squelch modes.
To Set Squelch Level
1.
Press
(SQL/B) to enter the squelch edit mode.
The squelch is displayed in the range '00' (open squelch) to
'15' (tight squelch). In the following example, the squelch
level is '02':
2.
Rotate the selector switch clockwise to increase, or counter
clockwise to decrease the displayed squelch level.
3.
Press the Toggle Light/ Enter Button momentarily (or any other
button) to adopt the selected squelch level and return to normal
operating mode (the radio automatically does this after 5 seconds
of inactivity).
The new squelch level is adopted.
When ' CTCSS' is off, the radio operates in CSQ mode.
When ''CTCSS' is on continuously, the radio operates in Coded
(PL/DPL) squelch mode.
When ''CTCSS' is flashing (which requires an optional Selective
Call board), the radio operates in Signaling squelch mode, and unmutes only after a
valid Voice Selective Call (SelCall) has been decoded.
