9. Maintenance and care
Remove any grime and dust with a soft, dry or silicon-treated cloth. Never
use detergents that could damage plastic parts.
Forming the flash capacitor
The flash capacitor incorporated in the flash unit undergoes a physical change
when the flash unit is not switched on for prolonged periods of time. For this
reason it is necessary to switch on the flash unit for approx. 10 minutes every
3 months (see 2.4!). The batteries must supply sufficient power for flash readi-
ness to be indicated within 1 minute after the flash unit was switched on.
