ABSTRACT:
A selective calling receiver enabling a user to know exactly whether the receiver used by the user is placed within an area where a transmitted radio wave can be received well. The selective calling receiver collates a frame synchronization signal in the transmitted signal at predetermined intervals and as far as the collation is successful, the synchronization is kept and the receiver is operated in an intermittent reception mode. When the collation is not successful, an alarm is issued after a predetermined time to inform the user that the receiver has been placed outside of the area where the transmitted radio wave can be received well.
