Canon A2 - Manual (Page 19)

1. Loading the Batteries
Turn the fastening screw counterclockwise with a coin to
remove the battery chamber cover. Use four new AA size
batteries of the same type and brand. The batteries’ contacts
should be wiped with a clean, soft cloth before loading to
avoid possible corrosion due to dirt or fingerprints. Insert the
batteries as indicated by the diagram on the bottom of the
power winder, and attach the chamber cover by turning the
screw with a coin. In general, new alkaline batteries will be
able to wind about 40 rolls and carbon-zinc about 20 rolls of
36-exposure film continuously under normal temperature.
* AA size Ni-Cd batteries oan be used in the Power Winder
A2. Use fully-charged batteries and follow the manufac­
turer’s instructions. Fully-charged Ni-Cd batteries will wind
about 60—80 rolls of 36-exposure film.
* Load the batteries correctly. If incorrectly loaded, the bat­
teries may burst and leak, damaging the winder.
* If the Power Winder A2 will not be used for about three
weeks or longer, remove the batteries from the battery
chamber lest they should leak.
