Troubleshooting; Maintenance And Care; Technical Data - Metz Mecablitz 44 MZ-2 Operating Instructions Manual

16. Troubleshooting

Should the LC display indicate meaningless information or should the flash
unit not work properly in the individual modes, then switch off the mecablitz
for about 10 seconds by its main switch. Check the camera settings and find
out if the flash unit's foot is correctly mounted in the camera's accessory shoe.
The mecablitz must operate properly when it is switched on again. Contact
your local dealer should this not be the case.

17. 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 (see Chapter 2.4). The batteries must supply sufficient power for flash
readiness to be indicated within 1 minute after the mecablitz was switched on.
