For many radio features, <F5> performs as the “Back” button. In these features, to return 
to the previous screen press <F5>.

Some radio features use “Left” and “Right” action buttons. On the Lightning Control 
Head, these buttons are the left and right arrows on the 4-Way Navigation Pad. On the 
Standard Control Head <F2> performs as the “Left” button, and <F3> performs as the 
“Right” button.

To exit menu mode, press <F6>.

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.

If the HOME option switch is programmed, pressing it selects the preprogrammed home 
channel. This provides a quick way of returning to a frequently used channel. Pressing and 
holding this switch until a tone sounds makes the currently selected channel the new 
Home. A secondary Home, Home2, may also be programmed.
