PROBLEM TO BE SOLVED: To prevent malfunction owing to the other radio wave of the same frequency by judging an identification code contained in received radio transmission. SOLUTION: CPU 123 of a vibration transmitter 120 generates transmission data containing the identification code of eight bits in a storage part 122 during a detection operation by an incoming call detection part 121 and transmits it through a modulator 124. On the other hand, CPU 205 of a vibration receiver 200 judges whether the output of a demodulator 202 is transmission data or not. When it is transmission data, the identification code is extracted and matching with the identification code in the storage part 203 is judged. When the result shows matching, a vibration motor 204 is turned on and a vibration operation is executed. |
