Tone scan
By monitoring a signal that is being operated with repeater, pocket
beep or tone squelch function, you can determine the tone fre-
quency necessary to access a repeater or open a squelch.
q
Set the frequency to be checked for a tone frequency or code.
w
Push [1•

• Repeat several times to select the tone condition or type to be
scanned. (One of “ ”, “ ” or “ ” appears)
• The tone scan can be operated even the tone condition or type is
selected.

r
When the CTCSS tone frequency or DTCS code is matched, the
squelch opens and the tone frequency or code is temporarily
programmed into the selected mode 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

This function uses subaudible tones for calling and can be used as
a “common pager” to inform you that someone has called when you
were away from the transceiver.
