TONE SQUELCH AND POCKET BEEP
N
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 the squelch.
q
Set the desired operating frequency and the desired oper-
ating mode.
w
Push and hold
[TONE]
(M/CALL) for 1 sec. to enter the
tone selection state.
e
Rotate
[DIAL]
to select either “TONE,” “TSQL” or “DTCS”
to be scanned, then push
[TONE]
(M/CALL) again.
r
Push and hold
[SCAN]
(VFO/MHz) to enter scan selection
state.
• To change the scanning direction, rotate
[DIAL]
.
t
Rotate
[DIAL]
to select “TONE,” then push
[SCAN]
(VFO/
MHz) again to start the tone scan.
[DIAL]
[TONE]
During repeater tone scan
During CTCSS frequency scan
During DTCS code scan
[SCAN]
y
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 feature, 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
e
.
-“TONE” : Tone encoder for repeater operation
-“TSQL”
: CTCSS tone encoder/decoder
-“DTCS” : DTCS tone encoder/decoder
u
Push
[SCAN]
(VFO/MHz) to stop the scan.
T-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.
