POCKET BEEP AND TONE SQUELCH
10
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 and hold [MONI•T/T-SCAN] for 1 sec and rotate
[DIAL] to select the tone type, tone squelch or DTCS, to
be scanned.
• Either “ ” or “
” appears. 
e
Push and hold [MONI•T/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 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 decoder depending on the selected tone con-
dition or type in step 
w
.
- “ ” : CTCSS tone decoder
- “
” : DTCS tone decoder
t
Push any switch for the main band or common switch to
stop the scan.
NOTE: The decoded tone frequency is programmed tem-
porarily when a memory is selected. However, this will be
cleared when the memory channel is re-selected.
