Inactivity Auto Power Off

Selects the amount of time that the radio waits before automatically powering off. This timer begins once a lack of radio-user interaction is determined by the radio. While the timer is active any button release on the radio resets the timer. During the last two minutes of this timer countdown, the radio generates audible and visual warnings until the timer expires or is reset. This selection applies on a radio-wide basis for all Conventional and Trunking communications channels. Time is in minutes.

When the Dual Radio - Radio Selection field is not set to "Secondary Radio", and
