Abstract of the Disclosure: In a radio paging receiver which is capable of responding to a message signal specific to the receiver and which comprises a display unit (90) and a message processing section (60) for making the display unit display the message signal, the message processing section monitors the message signal to produce a drive signal after reception of the message signal until the message signal is delivered to the display unit. Responsive to the drive signal, a combination of transistors (3 and 2) keeps power supply of a power source 18 to the message processing section as long as the drive signal is produced. Such power supply is carried out regardless of a state of a power supply switch (20). A decoder (40) makes a speaker (80) generate an alarm in response to the drive signal after the power supply switch is put into an off state. The alarm lasts until the switch is put into an on state. The message processing section may comprise 3 RAM for storing the message signal as a stored signal and another RAM for storing specific information indicating whether or not the stored signal is delivered to the display unit. Alternatively, such specific information may be stored in a memory included in the decoder.
