SUBAUDIBLE TONES

■

By monitoring a signal that is being operated with a repeater,
pocket beep or tone squelch function, you can determine the
tone frequency necessary to access a repeater or open the
squelch.

q Set the frequency to be checked for a tone frequency or

code.

w Push 

, then push 

.

• Repeat several times to select the tone condition or type to be

scanned. (One of “ ,” “ ” or “ ” appears)

• The tone scan can be operated even if the tone condition or type

is not 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 w.
