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-
