ABSTRACT:
The message transmitter transmits a re-calling identification signal with a message, and a receiver identifies this signal. Thereby the message transmitter can indicate selectively the re-calling of the receiver. If the message is not confirmed, the receiver performs re-calling according to a previously set time interval with a second sound pattern different from the normal sound pattern for indicating that this message is an unconfirmed message until the message is confirmed. The receiver continues to perform the calling operation periodically until the receiver holder cancels the re-calling. Meanwhile the message is confirmed by switch operation with a third sound pattern of three short sounds which are not noisy.
