CTCSS Privacy Codes

•

CTCSS (Continuous Tone Coded Squelch System) is an advanced tone coding system allowing you to select one (1) of 38 privacy codes to reduce interference from other users on the channel.

If you are using a privacy code, both radios must be tuned to the same channel and privacy code to communicate. Each channel will remember the last privacy code you selected.
