First Claim
1. A portable telecommunications apparatus capable of communicating with a destination communication apparatus through a radio telecommunications channel, comprising:
- a detector which detects if the portable telecommunication apparatus has entered a service area of the destination communication apparatus;
a sound generator which notifies a user by a sound when it is detected by the detector that the portable telecommunications apparatus has entered the service area of the destination communication apparatus; and
a sounding mode setting device which sets a sounding mode in which the sound is generated by said sound generator when it is detected by the detector that the portable telecommunication apparatus has entered the service area of the destination communication apparatus;
wherein said destination communication apparatus is a public radio base station connected to a telecommunications network; and
said portable telecommunication apparatus is a portable telephone set capable of setting up a radio telecommunications channel with said public radio base station and provided with a setting device for setting a telephone number and a photo-sensor for sensing light so that said portable telecommunications apparatus calls the telephone number set by said setting device when said photo-sensor detects light within a predetermined period of time after detection of when the start where the portable telecommunication apparatus is located in the service area of said destination communication apparatus.

Abstract
A portable telecommunications apparatus which is capable of communicating with a destination communication apparatus, such as a public radio base station, through a radio telecommunications channel, including: a detector which detects if the portable telecommunication apparatus has entered a service area of the destination communication apparatus. A sound generator notifies a user by a sound when it is detected that the portable telecommunications apparatus has entered the service area of the destination communication apparatus, and a sounding mode setting device which sets a sounding mode in which the sound is generated by the sound generator when it is detected that the portable telecommunication apparatus has entered the service area of the destination communication apparatus. The portable telecommunication apparatus, which may be a portable telephone set, is provided with a setting device for setting a telephone number and a photo-sensor for sensing light so that the portable telecommunications apparatus calls the telephone number set by the setting device when the photo-sensor detects light within a predetermined period of time after the detection of when the portable telecommunications apparatus is located in the service area of a destination communication apparatus
