In operating situations where you don’t know the CTCSS or 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. Two things must be remembered in this regard:
ˆ You must be sure that your repeater uses the same tone type (CTCSS vs. DCS).
ˆ 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
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-
cussions). In the case of CTCSS, “ ” will appear on the display; in the case of
DCS, “ ” will appear on the display.
2. Press the [ F/W
] key, then press the [

(
CODE
)] key.
3. Press and hold in the [ BAND
(
SCN
)
BND DN
] key for one sec-
ond to start scanning for the incoming CTCSS or DCS tone/
code.
4. 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
[
BAND
(
SCN
)
BND DN
] key to lock in that tone/code, then press the [
F/W
] 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 may listen to the (muted) signal from the other station during Tone Scanning when
Set Mode Item 68:

Tone Scanning works either in the VFO or Memory modes.
