Will be That is, the user checks the backup date and time displayed on the display unit 19, and instructs to rewrite the data when judging that the data in the RAM 18 may be rewritten with the backup data.

If there is no data rewriting instruction, the result of the determination in step S48 is "NO", the process is terminated, and the process returns to the normal process. On the other hand, if there is an instruction to rewrite data, the result of the determination in step S48 is "YES", and the flow proceeds to step S50. In step S50, data reset is performed to clear the data currently stored in the RAM 18. Next, the process proceeds to step S52, where the data request code for instructing the transmission of the backup data is transmitted to the antenna ANT via the communication control unit 11 and the transmission / reception unit 10.
