This is different from the usual method of restoring normal operation, and it applies only to
the configuration of the CTCSS/DCS frequencies. Remember to restore the default setting
“
R-N.T-N
” (Receive and transmit the Normal DCS Tone) when done.

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:
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
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 discus-
sions). In the case of CTCSS, “
” will
appear on the display; in the case of DCS,
“
” will appear on the display.
2.
Press and hold in the [
TXPO
] key for one second to enter the Set mode.
3.
Rotate the
DIAL
knob to select Set Mode
Item 86:
TN FRQ
when TONE SQL is se-
lected, or Set Mode Item 24:
DCS CD
dur-
ing DCS operation.
Note
: Do not forget to pull the
DIAL
knob to rotate the
DIAL
knob.
4.
Press the [
TXPO
] key momentarily to enable
adjustment of the selected Set Mode Item.
5.
Press and hold in the [
BAND
] key for one
second, until “
T SRCH
” (for CTCSS Tone
Search) or “
D SRCH
” (for DCS Tone Search)
appears on the display, then release the
[
BAND
] key to start scanning for the incom-
ing 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 [
BAND
] key to lock in that tone/code, then
press and hold the [
TXPO
] key for one second to exit to normal operation.
