PURPOSE:To provide the structure of the guide lamp control unit which is compact and reduce miswiring. CONSTITUTION:A combined circuit of a 1st diode 8, a 2nd diode 10, and a 3rd diode 2 controls the xenon lamps of all guide lamps and also controls the xenon lamp of a specific guide lamp and speech output individually when the xenon lamps of all the guide lamps illuminate. When an emergency broadcast is delivered through a microphone, the speech output of all the guide lamps is stopped without changing the state of the xenon lamps of all the guide lamps. Thus, the combined circuit of the diodes 8, 10, and 12 is used to pattern the operation, make the unit compact, and reduce miswiring. |
