ABSTRACT:
A radio selective calling receiver which has at least a switch operated by a user to perform operations including resetting of sound generation, ON/OFF of display, time correction, and read access to a stored message and whose switch interrupt processing performed by operating the switch is performed by starting a main clock, includes a radio unit operation determination unit for determining whether a radio unit which demodulates a radio signal received from a base station is performing a reception operation. If the radio unit operation determination unit determines that the radio unit is performing the reception operation, switch interrupt processing is not performed even when the user operates the switch. With this arrangement, an erroneous operation due to harmonic noise generated from the main clock in the reception operation and noise generated from the CPU operated by the main clock during the reception operation of the radio unit can be prevented.
