Squelch status indicator is displayed.
Digital PTT ID Support
This feature allows you to see the radio ID (number) of the
radio from whom you are currently receiving a
transmission. This ID, consisting up to a maximum of eight
characters, can be viewed by both the receiving radio and
the dispatcher.
The ID number of your radio is also automatically sent
every time the PTT button is pressed. This is a per-channel
feature. For digital voice transmissions, the ID of your radio
is sent continuously during the voice message.
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:
