POCKET BEEP AND TONE SQUELCH

■
Tone scan
By monitoring a signal that is being operated with pocket
beep, tone or DTCS squelch function, you can determine the
tone frequency or DTCS code necessary to open a squelch.
q
Set the desired operating frequency or memory channel to
be checked for a tone frequency or code.
w
Push [TONE•T-SCAN] several times to select the tone
type, tone squelch or DTCS, to be scanned.
• Either “T SQL” or “DTCS” appears
e
Push [TONE•T-SCAN] for 1 sec. to start the tone scan.
• To change the scanning direction, rotate [DIAL].
r
When the CTCSS tone frequency or 3-digit DTCS code is
matched, the squelch opens and the tone frequency is
temporarily programmed into the selected condition such
as memory or call channel.
• The tone scan pauses when a CTCSS tone frequency or 3-digit
DTCS code is detected.
• The decoded CTCSS tone frequency or 3-digit DTCS code is
used for the tone encoder or tone encoder/decoder depending
on the selected tone condition or type in step
w
.
- “T SQL”
: CTCSS tone encoder/decoder
- “DTCS”
: DTCS tone encoder/decoder
t
Push [TONE•T-SCAN] to stop the scan.
z
Set the frequency or memory channel to be
checked for a tone frequency.
x
Selects the tone type to be scanned.
• Push [FUNC] then push; [
SIMP
9(TSQL)] for tone
squelch; [
HIGH
4(DTCS)] for DTCS squelch.
c
Push [FUNC] then [
SCAN
2(T-SCAN)] to start
the tone scan.
v
When the tone frequency is matched, the
squelch opens and the tone frequency is pro-
grammed into the selected mode such as
memory or call channel.
b
Push [
CLR
A(MW)] to stop the scan.
☞
NOTE:
The decoded tone frequency is programmed tem-
porarily when a memory or call channel is selected. How-
ever, this will be cleared when the memory/call channel is
re-selected.

During CTCSS frequency scan
During DTCS code scan
Push [TONE•T-SCAN] for 1 sec. to start tone scan.
