SUBAUDIBLE TONE OPERATION
■ Tone scan
The transceiver can detect the subaudible tone frequency in a
received signal. By monitoring a signal that is being transmit-
ted on a repeater input frequency, you can determine the tone
frequency required to access the repeater.
q Set the desired frequency or memory channel to be
checked for a tone frequency.
w Turn the tone squelch ON or OFF to check the tone
squelch frequency or repeater tone frequency, respectively.

e Push the desired band’s [ (M/C) SCN] for 2 sec. to enter the
scan screen.
• Push [CHG/L] if [(M/C) SCN] is not displayed.
• If the pocket beep function is activated, the transceiver automat-
ically selects the tone squelch function when the scan screen is
selected.
r Push [TON] momentarily to start the tone scan.
• Decimal point flashes while scanning.
• To change the scanning direction, rotate the desired band’s tun-
ing dial.
t When the tone frequency is detected, the tone scan
pauses.
• The tone frequency is set temporarily on a memory or call chan-
nel. Program into the memory or call channel to store the tone
frequency permanently.
• The decoded tone frequency is used for the repeater tone fre-
quency or tone squelch frequency, depending on the tone
squelch ON/OFF setting.
y To stop the scan, push [TON] again.
u Push [ (MAIN) í ] for 2 sec. to exit the scan screen.
