ABSTRACT:
A call number of a selective calling receiver stored in an ID-ROM is ready by an ID number reading portion to be sent from an infrared ray outputting portion as an infrared ray signal. An infrared ray signal given from a further selective calling receiver is converted into an electric signal by an infrared ray sensor and its call number is detected from the electric signal by an ID number detecting portion to be additionally registered in the ID-ROM.
