<p>PROBLEM TO BE SOLVED: To prevent a fault in incoming processing, shortening of battery life, malfunctions in a circuit or wiring or shortening of a service life caused by the reduction of an operating current in a wireless part or control part by suppressing an excessive peak current value at the time of incoming call. SOLUTION: Concerning a portable radio communication apparatus, in incoming call reporting processing, a light emitter 6 emits intermittently light and a sounder 7 emits intermittently sound. Under control of by control means 9, light emitting operation and sounding operation are adjusted not to overlap with each other by shifting the light emitting period of the light emitter 6 and the sounding period of the sounder 7. Thus, timing is deviated for a light emitting operation current and a sounding operation current and a current to flow in incoming call reporting processing is smoothed.</p> |
