• If you drop the equipment and the casing breaks open to expose the internal parts, do not touch the internal parts due to the possibility of electrical shock.
• Do not disassemble or modify the equipment. High-voltage internal parts can cause electrical shock.
• Do not look at the sun or an extremely bright light source through the camera or lens. Doing so may damage your vision.
• Keep the camera from the reach of small children. The neck strap can accidentally choke the child.
• Do not store the equipment in dusty or humid places. This is to prevent fire and 
electrical shock.
• Before using the camera inside an airplane or hospital, check if it is allowed. Electromagnetic waves emitted by the camera may interfere with the plane’s 
instruments or the hospital’s medical equipment.
• To prevent fire and electrical shock, follow the safeguards below:- Always insert the power plug all the way in.
- Do not handle a power plug with wet hands.
- When unplugging a power plug, grasp and pull the plug instead of the cord.
- Do not scratch, cut, or excessively bend the cord or put a heavy object on the cord. 
Also do not twist or tie the cords.
- Do not connect too many power plugs to the same power outlet.
- Do not use a cord whose insulation has been damaged.
• Occasionally unplug the power plug and use a dry cloth to clean off the dust around  the power outlet. If the surrounding is dusty, humid, or oily, the dust on the power outlet 
may become moist and short-circuit the outlet to cause a fire.
Preventing Injury or Equipment Damage
• Do not leave equipment inside a car under the hot sun or near a heat source. The equipment may become hot and cause skin burns.
• Do not carry the camera around while it is attached to a tripod. Doing so may cause injury. Also make sure the tripod is sturdy enough to support the camera and lens.
• Do not leave a lens or lens-attached camera under the sun without the lens cap attached. Otherwise, the lens may concentrate the sun’s rays and cause a fire.
• Do not cover or wrap the battery-recharging apparatus with a cloth. Doing so may trap heat within and cause the casing to deform or catch fire.
• If you drop the camera in water or if water or metal fragments enter inside the camera, promptly remove the battery pack and back-up battery. This is to prevent fire and 
electrical shock.
• Do not use or leave the battery pack or back-up battery in a hot environment. Doing so 
may cause battery leakage or a shorter battery life. The battery pack or back-up 
battery can also become hot and cause skin burns.
• Do not use paint thinner, benzene, or other organic solvents to clean the equipment. Doing so may cause fire or a health hazard.
If the product does not work properly or requires repair, contact 
your dealer or your nearest Canon Service Center.

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. If you 
accidentally drop the camera into water, 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 wet cloth.
  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 misoperation 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.
  Use a blower to blow away dust on the lens, viewfinder, reflex mirror, and 
focusing screen. 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 
misoperation.
  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, do not use the camera. This is to avoid 
damaging the camera. If there is condensation, remove the lens, CF card 
and battery from the camera, and wait until the condensation has 
evaporated before using the camera.
  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 corrosive chemicals such as a 
darkroom or chemical lab.
  If the camera has not been used for an extended period, test all its functions 
before using the camera. If you have not used the camera for some time or if 
there is an important shoot coming up, have the camera checked by your 
Canon dealer or check the camera yourself and make sure it is working 
properly.
Handling Precautions  
						

							
13
Handling Precautions
LCD Panel and LCD Monitor Although the LCD monitor is manufactured with very high precision 
technology with over 99.99% effective pixels, there might be a few dead 
pixels among the remaining 0.01% or less pixels. Dead pixels displaying 
only black or red, etc., are not a malfunction. They do not affect the images 
recorded.
  If the LCD monitor is left on for a prolonged period, screen burn-in may occur 
where you see remnants of what was displayed. However, this is only 
temporarily and will disappear when the camera is left unused for a few 
days.
CF Card The CF card is a precision device. Do not drop the CF card or subject it to 
vibration. Doing so could damage the images recorded on them.
  Do not store or use the CF card near anything having a strong magnetic field 
such as a TV set, speakers, or magnet. Also avoid places prone to having 
static electricity. Otherwise, the images recorded on the CF card might be 
lost.
  Do not leave the CF card in direct sunlight or near a heat source. Doing so 
can warp the cards and make them unusable.
  Do not spill any liquid onto the CF card.
  Always store your CF cards in a case to protect the data stored on them.
  Do not bend the card or subject it to any excessive force or physical shock.
  Do not store the CF card in hot, dusty, or humid locations.
Lens Electrical ContactsAfter detaching the lens from the camera, attach the lens 
caps or put down the lens with the rear end up to avoid 
scratching the lens surface and electrical contacts.
Cautions for Prolonged UseWhen you shoot continuously for a prolonged period or use Live View shooting 
for a long period, the camera may become hot. Although this is not a 
malfunction, holding the hot camera for a long period can cause slight skin 
burns.
