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.
