Squelch Level, or press the preprogrammed Adjust Squelch Level key. The radio switches among three levels, i.e. Open, Normal, and Tight (from low to high).
Generally, a higher squelch level requires higher signal strength. If the squelch level is set to Open, the speaker will always keep turned on.
CTCSS/CDCSS
The Continuous Tone- Coded Squelch System (CTCSS)/Continuous Digital- Coded Squelch System (CDCSS) feature allows the radio to filter out unwanted voice on the current channel. With this feature enabled, the radio’s speaker is turned on only when the CTCSS/CDCSS code received matches the CTCSS/CDCSS code set for the radio.
