Convenient Functions
Communicating with specific stations
Using the tone squelch function
This radio is equipped with the CTCSS (Continuous Tone-coded Squelch System which
allows audio to be heard only when receiving signals containing the same frequency
tone as the tone that has been set in the tone squelch menu. By matching the tone
frequency with the partner station in advance, a quiet standby monitoring is possible.
Caution
CTCSS does not function in digital modes. To transmit a signal using a CTCSS code, use the
key to switch the communication mode to AMS (Auto Mode Select function) or analog (FM) mode.

The tone frequency can be selected from 50 frequencies (from 67.0 Hz to 254.1 Hz).
