Metz Mecablitz 54 MZ-3 - Manual (Page 86)

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 under-
goes a physical change when the flashgun is not swit-
ched 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 suffi-
cient power for flash-readiness to be indicated within
one minute after the mecablitz was switched on.
