Care And Maintenance; Technical Data - Metz MECABLITZ 45 CL-1 NiMH Mode D'emploi

the sensor of the flashgun cuts out the flash too soon with the result that the
actual subject is too dark. With a dark background the flash is cut out too
late so that the actual subject is too bright.
Bright background:
Open the camera aperture by 1/2 to 1 f-stop
(e.g. from f/5.6 to f/4).
Dark background:
Close the aperture by 1/2 to 1 f-stop
(e.g. from f/8 to f/11).

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.
