Maintenance And Care; Technical Data - Metz MECABLITZ 70 MZ-4 Manual De Instrucciones

With some cameras, manual flash exposure corrections must be adjusted on
the camera (see the operating instructions for the given camera). In this event
the mecablitz will not display a correction value.
Some cameras permit manual flash exposure corrections to be completed on
the camera or on the flash unit. Please refer to the operating instructions for
the given camera or the SCA adapter to establish which setting has priority.

15. 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 flashgun undergoes a physical change
when the flashgun is not switched on for prolonged periods of time. For this
reason it is necessary to switch on the flashgun for approx. 10 minutes every 3
months. The battery must supply sufficient power for flash-readiness to be indi-
cated within one minute after the mecablitz was switched on.
