Abstract
A radio communication system is used with an electronic appliance such as a wristwatch. The radio communication system includes a single transmitter unit including a first reference clock pulse generator which transmits paging data together with message data. A plurality of receiver units each have a second reference clock pulse generator which is built in the appliance, to decode the paging and message data uniquely characterizing that receiver unit with the help of a second reference clock pulse which has been synchronized with a first reference clock pulse. The paged operator is warned and the message is displayed.
