4.3 Time-Out Timer
The time-out timer disables the transmitter if it is keyed for longer than the programmed
time. It can be programmed on each channel for times of 15 seconds to 3 minutes, 45
seconds or it can be disabled.
If the transmitter is keyed continuously for longer than the programmed time, the
transmitter is disabled, a continuous tone sounds, and “TX TIMEOUT” is displayed. Five
seconds before time-out occurs, a warning beep sounds to indicate that time-out is
approaching. The timer and tone are reset by releasing the PTT switch.
A different time can be programmed for each system, and the timer can be enabled or
disabled on each conventional channel. With conventional channels, a penalty time can
also be programmed that prevents further transmissions for a certain time after the
transmitter is disabled (see Section 5.5).
One use of this feature is to prevent a channel from being kept busy for an extended period
by an accidentally keyed transmitter. It can also prevent possible transmitter damage
caused by transmitting for an excessively long period.
