Suitable batteries/rechargeable batteries
Please only use the power sources given above. If
other power sources are used, there is a risk of
damaging the flash unit.
If your flash unit is not going to be used for an
extended period of time, remove the batteries.
Replacing batteries
When inserting batteries, ensure that the polarity is
correct and matches the symbols in the battery
compartment. Inserting the batteries in the wrong
direction can destroy the flash unit! Always replace
all batteries simultaneously, and make sure that

capacity.
Flat or dead batteries should not be disposed of
with ordinary household waste. Help protect the
environment, and dispose of flat/dead batteries at
the appropriate collection points.
