CTCSS FIND
This transceiver can detect the CTCSS tone frequency in the re-
ceived signal. By monitoring a signal that is being transmitted from
the other station, you can determine the tone frequency required to
communicate with them.
This function very useful when you are going to communicate with
unknown CTCSS code number stations. ‘CTCSS FIND’ scans all
of the CTCSS codes, then stops when a tone code is detected.
q While pushing and holding [S-Ring/C-Ring], [MONI], turn [VOL]

w Select the desired CH 1 to CH 15 that you want to assign the
CTCSS tone code.
