IMPORTANT SAFEGUARDS

!

When using your photographic equipment,
follow the following basic safety precautions:

Do not fire flashes from a short distance
directly into the eyes of a person or animal.
This can cause damage to the retina and
may even lead to blindness.

Use only the power sources specified in the
operation instructions.

Never attempt to open or short-circuit
batteries.

Never expose dry or rechargeable batteries
to excessive temperature such as intensive
sunlight or fire.

Always switch off the flashgun before
changing batteries.

Do not attempt to open the flashgun
because the electronic circuit contains high
voltage.

In case the flashgun is so badly damaged
that the internal components are exposed,
the flashgun may not be used until it has
been repaired. Remove the batteries to
prevent inadvertent use.

Never try to repair the flashgun by yourself.
If there are any problems, contact the
customer service.
