 A. Cabin Illumination The cabin lamps are distributed in four strips throughout the cabin. The four strips are divided for control purposes into two pairs. The two outboard strips are designated as WINDOW (WDO) lights and the two center strips as CEILING (CLG) lights. The system is designed so that the window and ceiling lights can be on together or separately. When on, the fluorescent lamps can be selected to 100 % (BRT), 50 % (DIM 1), or 10 % (DIM 2) intensity. Each fluorescent lamp is installed in a holder which contains an integral ballast unit. The units are supplied with 115VAC from busbars 212XP and 214XP through circuit breakers 300LG thru 307LG (cabin lighting) and 308LG (entrance lighting). The lighting system is controlled from the forward attendant panel 120RH, which contains the following membrane switches:
