CTCSS (Continuous Tone Coded Squelch
System) is a quieting system that allows a
group of radios to talk to each other without
hearing other users on the channel. The system
applies a continuous low level tone to your
transmission, and a matching tone decoder to
your receiver's squelch. When CTCSS is
enabled the channel remains quiet until
someone transmits using the same tone. When
the transmission ends, the channel becomes
quiet again. By using different tones, several
groups of people can share the same channel
without disturbing each other.

contact your dealer to arrange for this feature
to be enabled.
The following description assumes CTCSS has
been enabled by your dealer.
The TX3400 allows CTCSS to be enabled or
disabled on individual channels. In addition, the
