Common Sense Camera Care and Practice
Batteries Care
1. The sealed, new battery which is supplied
with this camera may have been subject to
storage conditions which have reduced its
service life. Therefore it is desirable to
replace it with a fresh battery as soon as
possible.
2. Carefully wipe the battery contacts before
inserting into the chamber. Failure to do so
may result in poor electrical contact and
consequent malfunctioning of the camera.
3. Always remove battery when camera is not
used for a while. Always carry spare batteries.
4. Battery life differs, depending on type, age,
storage condition, ambient temperature,
frequency of use etc.
5. Be sure to match the poles of the battery with
those shown in the diagram in the chamber.
6 Always keep batteries out of the reach of
children and never throw used batteries into a
fire or expose to excessive heat.
7. When going on trips be sure to carry spare
batteries to ensure that the camera will
function. Also, as batteries tend to temporarily
malfunction at temperatures below freezing,
when photographing in extremely cold
climates, carry the External Battery Case.
8. When you carry spare batteries, leave them in
the original factory packaging. If they are
"unpackaged", be sure to wrap them carefully
in order to prevent them touching each other
or any metal objects which can cause them to
short circuit and become useless.
