■ Tone scan
By monitoring a signal on a repeater, or using 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.

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.
- No indication: Cannot be used for operation.
