High Speed Synchronisation; Cordless Remote Flash Control; Preflash Function For Red-Eye Reduction; Optional Extras - Metz MECABLITZ 54 AF-1 Minolta Bedienungsanleitung

6.1.2 High-speed synchronisation (HSS)
For system-induced reasons, high-speed synchronisation is not supported by
the flash unit.

6.1.3 Cordless REMOTE flash control

For system-induced reasons the cordless REMOTE flash control is not sup-
ported by the flash unit.

6.1.4 Preflash function for red-eye reduction

Various cameras offer the possibility to activate a preflash for red-eye re-
duction. This function only supports the flash unit integrated in the camera. It
does not support external flash units.

7. Optional extras

No guarantee is given for malfunctions and damage to the flash unit
caused by the use of accessories from other manufacturers!
• Wide-angle diffuser 44-21
(Item No. 000044217)
For full illumination in conjunction with lenses of 20 mm and up. The range
is reduced by the factor 1.4 due to the corresponding loss of light.
• Colour filter set 44-32
(Item No. 00004432A)
Consists of 4 colour filters to achieve special lighting effects, plus a clear fil-
ter to hold colour foils in any colour.
• Mecabounce 44-90
(Item No. 000044900)
A diffuser to achieve soft illumination in the simplest possible manner. The
effect is very impressive because the pictures are given a very soft atmos-
phere. Facial colours are rendered more naturally. However, loss of light
halves the maximum flash range.
• Bounce diffuser 54-23
(Item No. 000054236)
The soft directed light diminishes dense shadows.

8. Advice in the event of a fault

Should the LC display indicate meaningless information or should the flash
unit not work properly in the individual modes, then switch off the flash unit
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 flash unit must operate properly when it is switched on again. Contact
your local dealer should this not be the case.

9. 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 flash unit for approx. 10 minutes every
3 months (see 2.4!). The batteries must supply sufficient power for flash readi-
ness to be indicated within 1 minute after the flash unit was switched on.
