8. Advice in the event of a fault
Should the LC display indicate meaningless information or should the flash
unit not work properly in the individual modes, then switch off the flash unit
for about 10 seconds by its main switch. Check the camera settings and find
out if the flash unit’s foot is correctly mounted in the camera’s accessory shoe.
The flash unit must operate properly when it is switched on again. Contact
your local dealer should this not be the case.
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.
