Function 2: TONE Search Scanning

In operating situations where you don’t know the CTCSS/DCS tone being used by

another station or stations, you can command the radio to listen to the incoming signal

and scan in search of the tone being used.

Enter Menu 31

/32

to start CTCSS/DCS searching.

If the Tone scan feature does not detect a tone or code, it will continue to scan

indefinitely. When this happens, it may be that the other station is not sending any tone.

You can press PTT key to halt the scan at any time.

You also can press MONI key during Tone scanning to listen to the (muted) signal from

the other station. When you release the MONI key, Tone scanning will resume.

Tone Scanning works either in the VFO or MR modes.

Function 3: TONE Calling (1750Hz)

If the repeaters in your country require a 1750Hz burst tone for access (typically in

Europe), you can press and hold CALL key for 2s and transmitter will automatically be

activated, and a 1750Hz audio tone will be superimposed on the carrier. Once access

to the repeater has been gained, you may release CALL and use PTT key for activating

the transmitter.
