the PTT switch is pressed during the penalty time, the time-out indication

When it expires, the transmitter is disabled and a warning tone sounds.
The transmitter remains disabled for the length of the penalty time, and a
beep sounds when it can be keyed again.

direct communication with a mobile without going through a repeater.
Repeater talk-around can be selected if the Repeater Talk-Around
option switch is programmed. When talk-around is enabled by this
switch, the icon is displayed and “RTA ON” is flashed in the display.
