Note: Subaudible tone search mode will be locked out for
channels that have been previously programmed for
subaudible tone. To perform a new subaudible tone search for
a previously programmed channel, re-program the frequency
for the channel first, and then enter subaudible tone search
mode. This is intended to prevent inadvertent reprogramming
of previously programmed channels.
Using Tone Search
1. Press .
2. To determine if a stored frequency has an associated
CTCSS tone or CDCSS tone, press
when your
scanner stops on a channel.
3. Press and hold until you hear two short beeps.
CTCSS and CDCSS display and begin flashing, and the
scanner starts searching for an associated CTCSS and
CDCSS tone. All tones are checked if the transmission is
long enough. If there is a break before a tone is
identified, then your scanner starts searching where it
left off when the transmission begins again.
Note: If a CTCSS or CDCSS tone has been stored in a
channel, then tone search is not available.
