A switch (11) is provided for this under the carrying handle, With the switch position on constant light, the lamps can be operated with normal or double intensity if connected to 220 volts. IF 12OV/25OW HELOGEN LAMPS ARE USED, THEIR INTENSITY IS INCREASED 4 TIMES. LONG FLASH SERIES WITH QUICK FLASH SEQUENCES SHOULD THEREFORE BE INTERRUPTED BY INTERVALS IN ORDER TO AVOID OVER-HEATING OF THE LAMPS. 4 Photocell The highly sensitive photocell built into a coaxial plug is simply plugged into the synchro connection instead of the synchro cable.
