10. Illumination with wide-angle diffuser
42
Your mecablitz provides full and even illumination of
normal 24 x 36 mm negatives when using lenses of
35 mm focal length and longer. A wide-angle diffuser
is supplied with the flashgun to increase the
coverage if you wish to use a 28 mm wide-angle
lens.
PLEASE NOTE: The use of the wide-angle
diffuser diminishes the effective range of
the flash!
To mount the wide-angle diffuser press it onto the
reflector until it clicks in at the sides.
Remove grime and dust with a soft, dry cloth. Do not
use cleaning agents as these could damage the
plastic parts.
Forming the flash capacitor
The flash capacitor incorporated in the flashgun
undergoes a physical change when the flashgun is
not switched on for prolonged periods. For this
reason it is necessary to switch on the flashgun for
approx. 10 minutes every 3 months and to fire a few
flashes The batteries must supply sufficient power to
light up the flash-ready light within one minute after
the flashgun was switched on.
Troubleshooting:
If the flashgun does not work as it should in the
individual modes, then proceed as follows:
• Switch off the flashgun with the main switch.
• Remove the rechargeable or dry-cell batteries for
a brief period, and then load them again.
