ķ
Transmission of a correction value for flash exposure from the mecablitz to
the camera is only possible in TTL mode with an SCA 3xx2 adapter which
supports this function.
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
indicated within one minute after the mecablitz was switched on.
