(Caution) The operating voltages specified below are used in common irrespective of the presence of signals. In this case, however, part of the operating voltages (red characters) may change according
to the signal conditions when the main power supply is turned on (POWER button ON).
Status of LED lighting: ★ for lighting in green, ★★ for unlighting, and ★★★ for lighting in red.
