1. CTCSS Code Selection

The Continuous Tone Coded Squelch System (CTCSS) is a
Squelch quieting system that allows groups of users to share
the same channel without disturbing each other. It uses 1 of
38 low frequency tones to open and close the Squelch on the
radio. The CTCSS codes do not prevent others from hearing your
transmission. They simply provide you with a quieter channel by
preventing you from hearing transmissions that are not using
the same code as you and are therefore not directed at you.
note: To communicate with other UHF radios using CTCSS,
all radios you wish to communicate with must be switched to
the same channel and have the same CTCSS code selected.
If you wish to receive signals from UHF radios that are not

channel or set the CTCSS code to 'oF' as described in the
following 'note'.
