Penalty Timer
A penalty timer may be programmed on conventional systems to prevent transmissions for
the programmed time after the time-out timer disables the transmitter (see Section 4.6,
"Time-Out Timer"). The penalty timer can be programmed for the same times as the time-
out timer, and timing starts when the PTT switch is released. If the PTT switch is pressed
while the timer is running the timer stops, and continues when the PTT switch is released.
When the penalty timer expires, a beep sounds and the transmitter can then be keyed.
