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.
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.
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”
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.
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.
