An arithmetic device includes a communication unit that communicates with another instrument, a first activation unit to which a first address is set, and a second activation unit to which a second address is set and at which a computer program can be updated by the first activation unit. When having determined that information of update that can be performed by the first activation unit is included in information acquired by the communication unit, the second activation unit transmits the second address to the first activation unit. When having received the second address from the second activation unit, the first activation unit changes the first address to the second address, establishes communication with the other instrument based on the second address, and performs update at the second activation unit based on update information transmitted from the other instrument.
