Squelch Level
This option can reduce background noise by adjusting the
squelch level when the radio is receiving signals. You may
set the squelch level to Tight, Normal, or Open using the
CPS. Normal squelch level is the default. Tight squelch level
can filter weak signals, and allow only strong signals to be
received. If the squelch level is set to Open (This parameter
value is 0), the radio will turn on the speaker and background
noise will be heard.
Procedure:
1. Log in to the CPS.
2. Go to “Conventional -> Channel -> Analog Channel ->
Selected Analog Channel” and set Rx/Tx CTCSS/CDCSS
Type to CDCSS.
CDCSS Invert
