Radio-wide Features
4.5 Function Recall
A function recall button or menu item can be programmed so that if the user presses this
button or activates its menu item, the radio enters Function Recall mode, and the display
flashes “Fnc Recall”. Pressing any button displays the function assigned to that button for
a specified period. If that same button is pressed again during the specified period, the
radio performs the function assigned to that button and then exits Function Recall mode.
Function Recall mode can also be exited by pressing the Function Recall button once
(without pressing another function button).
Note If the user presses a function button programmed for Emergency while Function Recall is
activated, Function Recall is aborted. The radio will proceed to perform the programmed
Emergency function.
4.6 Time-Out Timer
The time-out timer disables the transmitter if it is keyed continuously for longer than the
programmed time. It can be programmed for 15-225 seconds or it can be disabled by
programming 0 seconds.
If the transmitter is keyed 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 may
also be programmed that prevents transmissions for a certain time after the transmitter is
disabled (see Section 5.5, "Penalty Timer").
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.
