Abstract
A wireless telephone set that performs digital communication employs light-emitting diodes for illumination, and for alerting the user to incoming calls. To avoid disruption of carrier signal frequencies, the light-emitting diodes are switched on and off only during idle periods, such as idle time slots in time-division multiple-access communication. If the wireless telephone also has a vibrator for alerting the user to incoming calls, switching of the vibrator is similarly synchronized with the idle time periods, and the light-emitting diodes are preferably disabled while the vibrator is in use.
