CTCSS FREQ. ID SCAN
This function scans through all CTCSS frequencies to
identify the incoming CTCSS frequency on the
received signal. You may find this useful when you
cannot recall the CTCSS frequency that the other
persons in your group are using.
1
While the CTCSS function is ON, press
[F]
,
[TONE] (1 s)
to start the CTCSS Freq. ID Scan
function.
•

[ ]
.
•
To quit the function, press
[ ]
or
[PTT]
.
•
When a CTCSS frequency is identified, the
identified frequency appears and blinks.
2
Press
[ ]
or
[MNU]
to program the identified
frequency in place of the current CTCSS
frequency. Otherwise, press
[ ]
if you do not
want to program the identified frequency.
•
Turn the
Tuning
control or press
[ ]
/
[ ]
while
the identified frequency is blinking to resume
scanning.

Note:
◆
Received signals are monitored through the speaker while
scanning is in progress.
◆
CTCSS Freq. ID Scan does not scan the tone if a signal is not
detected.
◆
If the CTCSS function is activated for both the A and B-band,
the scan speed may be slower.
DCS
DCS is similar to CTCSS. However, instead of using
an analog audio tone, it uses a continuous sub-
audible digital waveform that represents a 3-digit
octal number. You can select a DCS code from
among the 104 DCS codes listed in the table below.
USING DCS
Press
[TONE]
until “DCS” appears.
•
Each time you press
[TONE]
, the icon cycles as
follows: “
” (TONE)
➞
“CT” (CTCSS)
➞
“DCS”
(DCS)
➞
“ ” (OFF)
➞
“
” (TONE).
When the DCS function is ON, you will hear calls only
when the selected DCS code is received. To answer
the call, press and hold the
PTT
switch, then speak
into the microphone.
Note:
You cannot use the DCS function and CTCSS/ Tone
functions simultaneously. Switching the DCS function ON after
having activated the CTCSS/ Tone functions deactivate the
CTCSS/ Tone functions.
SELECTING A DCS CODE
1
While in DCS mode {above}, press
[F]
,
[TONE]
.
•
The current DCS code appears.
2
Turn the
Tuning
control or press
[ ]
/
[ ]
to select
your desired DCS code.
•
The available DCS codes are shown in the
following table.
