CANNING
In operating situations where you don’t know the CTCSS or DCS tone being used by an-
other station or stations, 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(s)
transmitting on the repeater uplink (input) frequency in order to allow Tone Search Scan-
ning to work.
To scan for the tone in use:
1. Set the radio up for either CTCSS or DCS Decoder operation (see the previous discus-
sion). In the case of CTCSS, “ENC DEC” will appear on the display; in the case of DCS,
“DCS” will appear on the display.
2. Press the [SET] key momentarily to enter the Set mode.
3. Rotate the “Main” band DIAL knob to select Menu #40 (TONE F) when CTCSS is se-
lected, or Menu #10 (DCS.COD) during DCS operation.
4. Press the “Main” band DIAL knob to enable adjustment of the selected Menu Item.
5. Press the “Main” band [SCN] key momentarily to start scanning for the incoming CTCSS
or DCS tone/code.
6. 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 “Main” band DIAL knob momentarily to lock in that
tone/code, then press and hold in the “Main” band DIAL knob for 1/2 second to save the
new setting and 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 [SCN] key to halt the scan at any time.
Tone Scanning works either in the VFO or Memory modes.
