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 squelch.
q
Push [
F
•
] to display the function guide.
w
Push [MENU](V/MHz•SCAN)
(Right band’s)
to enter MENU
screen.
e
Rotate [DIAL] to select “DUP/TONE…” then push
[MAIN•BAND].
r
Rotate [DIAL] to select either “REPEATER TONE,”
“CTCSS TONE” or “DTCS CODE” to be scanned.
t
Push [SCAN](TONE•DTMF) to start tone scan.
• To change the scanning direction, rotate [DIAL].
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
r
.
- “REPEATER TONE” : Tone encoder for repeater operation
- “CTCSS TONE”
: CTCSS tone encoder/decoder
- “DTCS”
: DTCS tone encoder/decoder
u
Push [V/MHz•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.
T-SCAN
During CTCSS
frequency scan
During DTCS code
scan
During Repeater
tone scan
[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.
