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 type of
tone, 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 temporar-
ily when a memory or call channel is selected. However, this
will be cleared when the memory/call channel is re-selected.
