Squelch Monitor
The Squelch is used to eliminate any unwanted background noise when there are
no signals present. The CP30 features a preset Squelch system. The Squelch level
has been preset to provide optimum performance in most situations but can be
adjusted through the menu.
The Squelch can be opened or closed by pressing the SQL key (default assigned
Side-Top-Key). When the Squelch is open the receiver’s background noise can be
heard, the Icon is displayed and the status LED lights green.
When the Squelch is closed, the radio remains quiet when there are no signals
present but any incoming signals will override the Squelch and be heard in the
speaker.
NOTE: If the SelCall quiet mode or CTCSS/DCS Silent mode is enabled, all signals
will be heard while the squelch is open.
