APPENDIX

MAINTENANCE AND CARE

The flash unit should be cleaned with a dry, soft cleaning cloth (e.g.
microfiber cloth). If, however, there is more dirt, the screen surface
can be cleaned with a very lightly moistened soft cloth.
Important:
Never use cleaning fluid. If cleaning liquid penetrates the screen
frame, the components will be irreparably damaged.
FORMATION OF THE FLASH CAPACITOR
The flash capacitor in the flash unit undergoes a physical change if
the unit is not switched on for a prolonged period. For this reason,
it is necessary to switch the unit on for approx. 10 minutes every
three months.
The power sources must supply enough energy to ensure that the
flash ready light lights up 30 s after switching on at the latest.

TROUBLESHOOTING

If the flash unit does not work as expected, for example, switch it
off for approx. 10 s using the main switch. Check the correct
position of the flash unit foot in the camera's accessory shoe and
the camera settings. Replace the batteries for new ones or freshly
charged rechargeable batteries. The flash unit should work
"normally" again after it is switched back on.
If this is not the case, please contact your specialist dealer.
Below there are a few problems that can occur in practice with the
flash. Possible causes or remedies for these problems are listed
under each of the points.
The flash unit AF auxiliary light is not activated
– The flash unit is not ready to flash.
– The camera is not working in the "Single-AF (S-AF)" mode.
– The camera only supports its own internal AF auxiliary light.
Various camera types support only the AF auxiliary light in the
flash unit with the camera's central AF sensor.
If a non-central AF sensor is selected, the AF auxiliary light is not
activated in the flash unit!
→ Activate central AF sensor!
