Pager receiver selectively changeable between call number reception and message reception
 In a pager receiver responsive to a call number signal preassigned thereto, a decoder (25) detects the call number signal to deliver a call indication signal to a loudspeaker (27) and is connected to a connector (36) for use in releasably receiving a controller (35) for detecting a message signal which follows the call number signal. A circuit portion (27, 150) is connected to the detector and the connector to produce the call indication signal simultaneously with detection of the call number signal when the decoder is singly operated. The circuit portion produces the call indication signal after detection of the message signal when the controller is coupled to the decoder through the connector.
