A remote control apparatus includes various operation keys and is connected to a plurality of electronic appliances through buses. If a timepiece reset mode is set on a side of the remote control apparatus and then a desired electronic appliance is selected, a protocol is established between the remote control apparatus and the desired electronic appliance. A command key for reset command input is activated after establishing a protocol. If a command key is operated, a reset command for the timepiece is transmitted to the desired electronic appliance to thereby reset a timepiece circuit provided in the desired electronic appliance. Because the protocol has been established at a time that the command key is operated, the timepiece circuit is reset immediately after operating the command key.
