■ Tone scan
By monitoring a signal using with pocket beep, tone or DTCS
squelch, you can determine the tone frequency or DTCS
code necessary to open the squelch.
q Set the desired operating frequency or memory channel to
be checked for a tone frequency or code.
• Push [MAIN] to select the desired band (left or right) as the main
band in advance.
w Push and hold [MONI•T/T-SCAN] for 1 sec and rotate the
main band’s [DIAL] to select the tone type, tone squelch or
DTCS, to be scanned.
•Either “ ” or “ ” appears.
e Push and hold [MONI•T/T-SCAN] for 1 sec. to start the
tone scan.
•To change the scanning direction, rotate the main band’s [DIAL].
r When the CTCSS tone frequency or 3-digit DTCS code is
matched, the squelch opens and the tone frequency is
temporarily programmed into the VFO or memory 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 decoder depending on the selected tone con-
dition or type in step w.
-“ ”: CTCSS tone decoder
-“ ”: DTCS tone decoder
t Or push any key for the main band or any of the shared
keys below the display to stop the scan.
NOTE: The decoded tone frequency is programmed tem-
porarily when a memory is selected. However, this will be
replaced by the programmed information when the mem-
ory channel is re-selected.
