<p>PROBLEM TO BE SOLVED: To execute the ID registration by the simple operation at a receiver side by storing ID received during an ON-period of a registering switch of a receiver in EEPROM inside of the receiver as ID of a transmitter to be recognized in the receiver. SOLUTION: An ID registering mode for writing ID received by a receiver 4 to EEPROM 13 is obtained by turning on a registering switch 12 of the receiver 4. On the other hand, at a transmitter side, the pressure data is transmitted as the pressure abnormality when the change of pressure by more than specific pressure generates as the result of the measurement of the pressure. In the ID registering, the pressure is changed by letting air out of a tire by pressing a shaft part of an air valve of the tire to be registered. The transmitter detects the change of pressure and transmits the data. When the reception of data for four wheels has been completed, the receiver 4 writes the received ID number to EEPROM 13. Whereby the ID registering operation can be executed by the simple setting operation of the receiver 4.</p> |
