Handling Precautions

Do not block the mirror operation with your fi nger, etc. Doing so may
cause a malfunction.

Use only a commercially available blower to blow away dust when it
adheres to the lens, viewfi nder, mirror, focusing screen etc. Do not use
cleaners that contain organic solvents to clean the camera body or lens.
For stubborn dirt, take the camera to the nearest Canon Service Center.

Do not touch the camera’s electrical contacts with your fi ngers. This is
to prevent the contacts from corroding. Corroded contacts can cause
camera malfunction.

If the camera is suddenly brought in from the cold into a warm room,
condensation may form on the camera and internal parts. To prevent
condensation, fi rst put the camera in a sealed plastic bag and let it adjust
to the warmer temperature before taking it out of the bag.

If condensation forms on the camera, to avoid damage, do not use the
camera or remove the lens, card, or battery.
Turn the camera off and wait until the moisture has fully evaporated
before resuming use. Even after the camera is completely dry, if it is still
internally cold, do not remove the lens, card, or battery until the camera
has adjusted to the ambient temperature.

If the camera will not be used for an extended period, remove the battery
and store the camera in a cool, dry, well-ventilated location. Even while
the camera is in storage, press the shutter button a few times once in a
while to check that the camera is still working.

Avoid storing the camera where there are chemicals that result in rust
and corrosion such as in a chemical lab.

If the camera has not been used for an extended period, test all its
functions before using it. If you have not used the camera for some time
or if there is an important shoot such as a foreign trip coming up, have
the camera checked by your nearest Canon Service Center or check the
camera yourself and make sure it is working properly.

If you repeat continuous shooting or perform Live View shooting or movie
shooting for a prolonged period, the camera may become hot. This is not
a malfunction.

If there is a bright light source inside or outside the image area, ghosting
may occur.
