15. Maintenance and care
Remove any grime and dust with a soft, dry or silicon-treated cloth. Never
use detergents – they may damage plastic parts.
Forming the flash capacitor
The flash capacitor incorporated in the flash unit undergoes a physical chan-
ge when the flash unit is not switched on for prolonged periods. For this rea-
son it is necessary to switch on the flash unit for approx. 10 minutes every 3
months. The batteries must supply sufficient power for flash readiness to be
indicated within 1 minute after the flash unit was switched on.
