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.
qSet the frequency to be checked for a tone frequency or
code.
wTurn the desired tone type, tone squelch or DTCS, ON in
expanded set mode.
One of TSQL or DTCS appears.
Even the pocket beep function is activated, the function is can-
celled when starts the tone scan.
eWhile pushing [FUNC], push [MODESCAN] 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 or
code is temporarily programmed into the selected condi-
tion, such as memory channel.
The tone scan pauses when a CTCSS tone frequency or 3-digit
DTCS code is detected.
For your convenient!
Even no tone type is selected, either tone squelch or DTCS,
pushing [MODESCAN] while pushing and holding [FUNC]
also start tone scan. In this case, the tone scan searching for
tone squelch frequency only.
NOTE: The decoded tone frequency or code is pro-
grammed temporarily when a memory channel is se-
lected. However, this will be cleared when the memory
channel is re-selected.
