ABSTRACT:
A radio selective calling receiver which can prevent reliably a radio section from being affected by a noise generated in a boosting circuit during an infrared-ray communication, whereby a reception sensitivity in the radio section can be prevented from being degraded. The radio selective calling receiver has a memory 14 for storing reception information received by the radio section 2 and an infrared-ray data communication section 24 for outputting the reception information stored in the memory 14 to an external terminal by means of an infrared ray and for receiving infrared-ray data from the external data terminal so as to cause a first control means 4 to control the infrared-ray data communication of the infrared-ray data communication section 24 if telecommunication dispatching is inputted and to cause a second control means 10 to inhibit the infrared-ray data communication during an operation of the radio section 2 even if the telecommunication dispatching is inputted.
