This conveniently eliminates unwanted audio and is useful in group
activities or security related activities where unwanted output can
be a problem. The function is similar to a CTCSS tone squelch.

using the optional CS-F11 cloning software. Using this software, the
transceiver's model, individual RX Code CH, TX Code CH, Special
Tone Link2 (must be 'E') in 5Tone screen, 5Tone Signaling Form in
Memory-CH screen, Log, RX C-No, Key&Display, Common Au-
toReset TimerB, and other settings related to operation can be set.
