Abstract
Radio transceivers are provided with a timing circuit that ends or terminates a radio transmission after a first time period, and an audible indication signals the end of the first time period. A battery voltage sensor reduces the period of the timing circuit in response to low battery voltage. Shorter period transmissions are still permitted for emergencies, and an audible indication is provided after the short time period to indicate low battery voltage.
