3.2 Power supply
Suitable batteries/rechargeable batteries
The flash unit can be operated with any of the following batteries:
• 4 NiCad batteries 1.2V, type IEC KR6 (size AA). They permit very fast recy-
cling times and are economical in use because they are rechargeable.
• 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 batteries 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-capa-
