3.2 Power supply
Suitable batteries/rechargeable batteries
The flash unit can be operated with any
of the following batteries:
• 4 nickel-metal-hydride batteries 1.2V,
type IEC HR6 (size AA). They have a
significantly higher capacity than
NiCad batteries and are less harmful
to the environment, since they have no
cadmium.
• 4 alkaline-manganese dry cell batte-
ries 1.5V, type IEC LR6 (size AA).
Maintenance-free power source for
moderate power requirements.
• 4 lithium batteries 1.5V, type IEC FR6
(size AA). Maintenance-free high-
capacity power source with a low self-
discharge rate.
• 4 NiCad batteries 1.2V, type IEC KR6
(size AA).
They permit very fast recycling times
and are eco-nomical in use because
they are rechargeable.
If your flash unit is not going to be used
for an extended period of time, remove
the batteries.
