10. Care and Maintenance
Remove dust and grime with a soft dry cloth, or a silicon-treated cloth. Do
not use detergents as these may damage the plastic parts.
Forming the flash capacitor
The flash capacitor incorporated in the flashgun undergoes a physical chan-
ge when the flashgun is not switched on for prolonged periods. For this rea-
son it is necessary to switch on the flashgun for approx. 10 minutes every 3
months. The battery must supply sufficient power to light up the flash-ready
light within one minute after the flashgun was switched on.
