Abstract
A radiotelephone (300) having timer shutoff feature and a roam shutoff feature. The timer shut off feature implements a process (102-114) in which a processor (310) determines (106) if a flip (408) is closed or an end key (410) has been pressed. If either of these events occur a timer is started (108). If the timer exceeds (110) a predetermined period of time before another phone call exists (112) the radiotelephone (300) is placed (114) in an off mode. The roam shutoff feature implements a process in which the processor (310) determines (116) if the radiotelephone (300) is in a roam mode. If the radiotelephone (300) is in a roam mode and no phone call exists (118) the radiotelephone is placed (114) in the off mode.
