Abstract:
An electronic apparatus, comprising:a reference signal generator configured to generate a reference signal; a temperature sensing unit configured to measure the internal temperature of the apparatus and to generate a temperature signal having a characteristic that varies in accordance with the internal temperature of the apparatus; a drive unit configured to generate a drive signal and to output the drive signal to a motor coil of a unit to be driven; a receiver configured to receive a signal transmitted from an external adjustment device via the motor coil; a detecting unit configured to detect the type of the signal received by the receiver; and an examining unit configured to output a test signal via the motor coil to the external adjustment device, the test signal being indicative of the temperature-varying characteristic of the temperature signal, based on the detection result of the detecting unit.
