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-
sion). In the case of CTCSS, “

Press and hold in the [

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/W
] key to lock in that tone/code, 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.
Tone Scanning works either in the VFO or Memory modes.
