Setting the Subaudible Tone Option

2:SCAN OPTION → 1:CONVENTIONAL → Channel No. → 3:TONE DATA

Some radio systems use special tones to prevent interference from other nearby systems operating on the same frequencies. When tones are being used, the radios only open squelch when a transmission with a matching tone is present on the frequency. Some services, such as FRS, GMRS, and Business Band refer to these tones as Quiet Codes, Privacy Codes, or similar and use a number to associate a particular tone. The table in the back of the manual provides a cross reference to common associations. For this feature to work, you need to turn on the Tone Mode (see “Setting Squelch Mode”).

1:CTCSS

Continuous Tone Coded Squelch System (CTCSS) is used with Amateur Radio, FRS, GMRS, Business Band, and other systems. When you select this option, the scanner only opens squelch when a matching CTCSS tone is present on the frequency.
