A remote control device includes one or more mode buttons which, when manipulated, cause plural controlled devices to assume preset configurations. The calculated reference voltage is calculated by the CPU based on a voltage drop value in main capacitors that occurs during a transfer time between the battery mode and the AC mode. The reinforcing structure is bonded to the exterior of the bladder, and may be recessed into the bladder. For the adjustment can be used spring loading, fluid pressure loading or gravity loading, for example. Since the buffer is managed in a FIFO manner, a single breakpoint register is sufficient to monitor addresses as they are provided by an address register for accessing the random access memory. Further, in a cold environment, the cooling fan is not actuated so that the performance at a low temperature is not deteriorated and so power consumption can be also saved.
