PROPER CARE OF THE CAMERA
^ Cleaning the Camera and Lens
Use a camel hair or blower brush to clean the film
cartridge chamber and the area around the multi-slot
take-up spool before loading film into the camera.
Also, use the brush to wisk away dirt and dust from
the eyepiece and the front and rear surfaces of the
lens. If salt water spray or fingerprints inadvertently
get on the lens, they should be cleaned off as soon as
possible using commercially-available cleaning tissue
and a good quality lens cleaning liquid. Put one or
two drops of cleaning liquid on the tissue, and
lightly wipe the lens in a circular motion from the
center toward the outer edges. Do not use a
handkerchief or other cloth, as the lens elements
may be permanently scratched. If you cannot
remove dust particles from the surface of the instant-
return mirror simply by brushing, you should not
attempt to clean the mirror yourself with tissue and
cleaning liquid. Only an authorized serviceman
should undertake this delicate task. Actually dirt on
the mirror has absolutely no effect on the quality of
your photographs.
B
Storing the Camera
If the camera will not be used for an extended length
of time, leave the shutter uncocked and remove the
mercury batteries. Take the camera out of its
eveready case and wrap it up in a clean, soft towel
together with silica gel or some other desiccant to
keep it dry.
C Using the Camera in Extremely
Cold Conditions
In severely cold weather (down to —20 C or —4 F),
you should keep the Canon EF inside your coat and
expose it to the outer air only when you are ready to
take a picture. This procedure is necessary primarily
to keep the mercury batteries warm. Since the film
gets brittle at low temperatures, perform film wind­
ing and rewinding as slowly as possible.
D
Having the Camera Serviced
You should never attempt to disassemble or repair
the Canon EF yourself! If the camera ceases to
function properly, it should be serviced by an
authorized Canon repair facility. See your local
camera dealer for further details.
