In operating situations where you don’t know the CTCSS or DCS tone being used by
another station, you can command the radio to listen to the incoming signal and scan in
search of the tone being used. Two things must be remembered in this regard:

€ You must be sure that your repeater uses the same tone type (CTCSS vs. DCS).
€ Some repeaters do not pass the CTCSS tone; you may have to listen to the station

transmitting on the repeater uplink (input) frequency in order to allow Tone Search
Scanning to work.

To scan for the tone in use:
1. Set the radio up for either CTCSS or DCS Decoder operation (see the previous dis-

cussion). In the case of CTCSS,
“TSQ

in the case of DCS, “DCS

4. Press and hold in the

key, the “TONE SEARCH

key to start scanning for the incoming CTCSS or DCS tone/code.

5. When the radio detects the correct tone or code, it will halt on that tone/code, and

audio will be allowed to pass. Press the

key to lock in that tone/code, then press

the

key to exit to normal operation.

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 the
PTT switch to halt the scan at any time.

You can also press the

key during Tone Scanning to listen to the (muted) signal from

the other station. When you release the

key, Tone Scanning will resume after about a

second.

Tone Scanning works either in the VFO or Memory modes.
