Handling Precautions
Camera Care
and Storage
{ 1 ) The camera is a precision instrument. Do not drop it or subject it to
physical shock.
{ 2 ) This camera is not waterproof and cannot be used underwater. If the
camera gets really wet, promptly consult your nearest Canon Service
Center. Wipe off any water droplets with a dry cloth. If the camera
has been exposed to salty air, wipe with a well-wrung damp cloth.
( 3 ) Do not leave the camera in places prone to excessive heat such as
in a car on a sunny day. Excessive heat can cause the camera to
malfunction.
{ 4 ) The camera contains precision electronic circuitry. Never attempt to
disassemble the camera.
(5 ) Use only a blower brush to blow away dust on the lens, viewfinder
eyepiece, focusing screen, film compartment, and mirror. Do not use
an organic solvent-containing cleaner to clean the camera body or
lens. For stubborn dirt, consult your nearest Canon Service Center.
( 6 ) The shutter curtains are extremely thin. Use only a blower to clean.
Be careful not to blow air too forcefully on the shutter curtains. The
shutter curtains can be easily deformed or damaged. Also, when
loading and unloading film, be careful not to touch the shutter
curtains.
(7) Do not touch the electrical contacts with your fingers. Otherwise
corrosion may develop on the contacts, resulting in improper camera
operation.
(8 ) If the camera is not to be used for an extended period, remove the
battery. Store the camera in a well-ventilated, cool, dry place. During
the storage period, release the shutter a few times once in a while.
(9) Avoid storing the camera in a laboratory, cabinet, etc., where
corrosive chemicals are present.
(10) If the camera has not been used for an extended period or if the
camera is to be used for an important event, check the operation of
all the camera controls or take it to your nearest Canon Service
Center.
