PURPOSE:To decrease the opportunity of intensional operation of other transmitter or receiver by adopting the constitution that a memory means for storing the content of a number set means and a transmission means for sending the content of the number setting means to the storage means are provided to a transmitter not having the number setting means to prevent simply crosstalk. CONSTITUTION:The number set means 2 is provided to the transmitter side and the storage means 10 is provided to the receiver side. A transceiver is connected by a connector 11 and a switch 12 is turned on to store the data of the number set means 2 of the transmitter to the storage means 10 of the receiver side. When the data similar to that of the number setting means 2 of the transmitter is stored in the storage means of the receiver by initial set, data transmission/reception between the transmitter and receiver is attained. When the data of the number set means 2 at the transmitter side differs from the storage data of the storage means at the receiver side, no transmission/ reception is attained. |
