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

to stop the scan.
z
Set the channel to be checked for a tone fre-
quency.

Selects the tone condition or type to be
scanned.

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.

NOTE:
The decoded tone frequency is programmed tem-

ever, this will be cleared when the memory/call channel is
re-selected.
