10 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 channel to be checked for a tone frequency or
code.
w Push [TONE ] several times to select the tone
condition or type to be scanned.
• One of “ ,” “ ” or “ ” appears
e Push [TONE ] 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.
- No indication : Cannot be used for operation.
- “ ” : CTCSS tone encoder
- “ ” : CTCSS tone encoder/decoder
- “ ” : DTCS tone encoder/decoder
t Push [V/MHz ] to stop the scan.
z Set the channel to be checked for a tone fre-
quency.
x Selects the tone condition or type to be
scanned.
• Push [FUNC] then push; [ DUP – 7(TONE)] for re-
peater tone; [ 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.
