When you have made your selection, press the [
H/L
] key momentarily, then press the
PTT
switch to save the new settings and exit to normal operation.
Remember that the DCS is an Encode/Decode system, so your receiver will
remain muted until a matching DCS code is received on an incoming trans-
mission. Switch the DCS off when you’re just tuning around the band!

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:
r
You must be sure that your repeater uses the same tone type (CTCSS vs. DCS).
r
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 [
H/L
] key for one second to enter the Set mode.
3.
Rotate the
DIAL
knob to select Set Mode Item 44:
TN FRQ
when TONE SQL is
selected, or Set Mode Item 14:
DCS CD
during DCS operation.
4.
Press the [
H/L
] key momentarily to enable adjustment of the
selected Set Mode Item.
5.
Press and hold in the [
BAND
] key for one second, appear
“
T SRCH
” (for CTCSS Tone Search) or “
D SRCH
” (for DCS
Tone Search) on the display, then release the [
BAND
] key 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 [
BAND
] key to lock in that tone/code, then
press
PTT
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 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.
