8 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 mecablitz for approx. 10 minutes every 3
months. The batteries must supply sufficient power for flash
readiness to be indicated within 1 minute after the mecablitz
was switched on.
Metz does not accept any liability for faulty functions
or damage to the mecablitz caused by the use of
accessories from other manufacturers!
