Smart PTT Feature (Conventional Only)

Smart PTT is a per-personality, programmable feature used
in conventional radio systems to keep radio users from
talking over other radio conversations.
When smart PTT is enabled in your radio, you cannot
transmit on an active channel.
If you try to transmit on an active smart-PTT channel, you
hear an alert tone, and the transmission is inhibited. The
LED lights up solid yellow to indicate that the channel is
busy.
The following table shows the variations of smart PTT:
