There are two ways you can
program your scanner to operate
with CTCSS. If you know the
CTCSS code that is used on a
particular frequency, you can
manually enter the code when you
are programming the scanner, or
any time afterwards.
You can also set a special search
code up that will instantly decode
the CTCSS code on a received
transmission. Channels
programmed with the search code
will receive all traffic on the
channel, and will instantly decode
and display any CTCSS code that
is found with the transmission.
You can then store the found code
in the channel memory with one
keystroke.
