Abstract:
1. A main body electric device configured to communicate with a slave electric device, the main body electric device comprising: an acquisition circuit configured to acquire an update program that includes at least a slave electric device update program for a slave control circuit that is configured to control the slave electric device, from an external device; and a main body control circuit configured to control the main body electric device; the main body control circuit being configured to suppress a generation of noise from a noise generating source that has a possibility to generate noise to a communication between the main body electric device and the slave electric device, and subsequently transmit the slave electric device update program to the slave control circuit in a second communication method that is faster than a first communication method, the first communication method being a communication method performed between the main body electric device and the slave electric device before the generation of noise is suppressed.
