MERCURY BATTERIES

Do not leave fingerprints or stains on the mercury
batteries. Before inserting the mercury batteries
into the camera, wipe all poles clean of all
fingerprints or stains with a dry cloth. If this is
not done, they may cause corrosion and damage
the contact points. When the camera is not to be
used for a prolonged period of time, remove the
mercury batteries and keep them in a dry place.
