Canon EOS-1D X Mark III DSLR Camera (Body Only) - Manual (Page 21)

Handling Precautions
Camera care
This camera is a precision instrument. Do not drop it or subject it to physical shock.
The camera is not waterproof and cannot be used underwater.
To maximize the camera's dust- and drip- resistance, keep the terminal cover, battery
release handle, card slot cover, and all other covers firmly closed.
This camera is designed to be dust- and drip- resistant, in order to help prevent sand,
dust, dirt, or water that falls on it unexpectedly from getting inside, but it is impossible to
prevent dirt, dust, water, or salt from getting inside at all. As far as possible, do not allow
dirt, dust, water, or salt to get on the camera.
If water gets on the camera, wipe it off with a dry and clean cloth. If dirt, dust, or salt gets
on the camera, wipe it off with a clean, well-wrung wet cloth.
Using the camera in dusty or dirty locations may lead to damage.
Cleaning the camera after use is recommended. Allowing dirt, dust, water, or salt to
remain on the camera may cause a malfunction.
If you accidentally drop the camera into water or are concerned that moisture (water),
dirt, dust, or salt may have gotten inside it, promptly consult the nearest Canon Service
Center.
Never leave the camera near anything having a strong magnetic field such as a magnet
or electric motor. Also, avoid using or leaving the camera near anything emitting strong
radio waves, such as a large antenna. Strong magnetic fields can cause camera
malfunction or destroy image data.
Do not leave the camera in excessive heat, such as in a car in direct sunlight. High
temperatures can cause the camera to malfunction.
The camera contains precision electronic circuitry. Never attempt to disassemble the
camera yourself.
Do not block the mirror operation with your finger, etc. Doing so may cause a
malfunction.
Use only a commercially available blower to blow away dust when it adheres to the lens,
viewfinder, 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 fingers. 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, first 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.
