In addition, in the maintenance mode, if the remaining amount of a battery is equal to or greater than a predetermined amount in the first mode, the wireless operation unit does not shift to the second mode, and if the remaining amount of the battery is less than the predetermined amount, the wireless operation unit shifts to the second mode.
