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:
m
You must be sure that your repeater uses the same tone type (CTCSS vs. DCS).
m
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:
Set the radio up for either CTCSS or DCS Decoder operation (see the previous discus-
sions). In the case of CTCSS, “
T SQ
” will appear on the display; in the case of DCS,
“
DCS
” will appear on the display.
Press the [
F
] key, then immediately press the [
M/V
(
SET
)] key to enter the Set mode.
Rotate the
DIAL
to select the “
TN SET
” Menu item (when TONE SQL is selected) or
“
DCS SET
” (during DCS operation).
Press the [
F
] key, then press and hold in the [
s
] or [
t
] key to start scanning for the
incoming CTCSS or DCS tone/code.
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 [
F
] key to lock in that tone/code.
Press the [
F
] key, then press the
PTT
key to save the new settings and exit to normal
operation.
If the Tone Scan feature does not detect a tone or code, it will continue to scan indefi-
nitely. 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 also can press the
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
after about a second.
