Although the touch panel of the operation unit 53 is not pressed as described above (No in step S302), the control unit 52 receives control data via the communication unit 51 (Yes in step S312). If the control data is "BUZZER_ON" (Yes in step S314), the buzzer flag in the storage unit 55 is set to "1". On the other hand, if the control data received via the communication unit 51 is "BUZZER_OFF" (Yes in step S318), the buzzer flag in the storage unit 55 is set to "0".

As a result, the control unit 52 changes the value of the buzzer flag set based on the control message received from the outside, similarly to the case where the “long press” or “continuous press” operation is performed on the touch panel of the operation unit 53. Based on this, it is possible to determine whether or not to generate an operation sound when the touch panel is operated (step S308), thereby controlling the operation sound (step S310).

If the received signal is neither "long press" nor "continuous press" (No in step S314 and No in step S318), the control unit 52 determines whether the signal is the second control signal. is determined (step S322). When the received signal is the second control signal (Yes in step S322), the control unit 52 executes processing based on the second control signal (step S324). If the received signal is not the second control signal (No in step S322), the control unit 52 returns to step S302.

Note that the control unit 52 repeats the above processes (steps S302 to S326) until there is an instruction to end this control process (No in step S326).
