An AC halogen lamp is used as Exposure Lamp LA1.
As the exposure level is adjusted on the control panel, the duty ratio of the pulse of AVR
Remote from PWB-A changes to increase or decrease the LA1 voltage, thereby chang-

In Photo mode, the voltages are varied on a level 3V (200V Areas: 6V) lower than the
manual Exposure Lamp voltages.
