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 if the tone condition or type is

• To change the scanning direction, push [∫] or [√].
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.
- “ ” : CTCSS tone encoder
- “ ” : CTCSS tone encoder/decoder
- “ ” : DTCS tone encoder/decoder
