Safety Warnings
Follow these safeguards and use the equipment properly to prevent injury, death, 
and material damage.
Preventing Serious Injury or Death
• To prevent fire, excessive heat, chemical leakage, and explosions, follow the safeguards below:
- Do not use any batteries, power sources, and accessories not specified in this 
booklet. Do not use any home-made or modified batteries.
- Do not short-circuit, disassemble, or modify the battery pack or back-up battery. Do  not apply heat or apply solder to the battery pack or back-up battery. Do not expose 
the battery pack or back-up battery to fire or water. And do not subject the battery 
pack or back-up battery to strong physical shock.
- Do not install the battery pack or back-up battery in reversed polarity (+ –). Do not 
mix new and old or different types of batteries.
- Do not recharge the battery pack outside the allowable ambient temperature range  of 0°C - 40°C (32°F - 104°F). Also, do not exceed the recharging time.
- Do not insert any foreign metallic objects into the electrical contacts of the camera,  accessories, connecting cables, etc.
• Keep the back-up battery away from children. If a child swallows the battery, consult a physician immediately. (Battery chemicals may harm the stomach and intestines.)
• When disposing of a battery pack or back-up battery, insulate the electrical contacts with tape to prevent contact with other metallic objects or batteries. This is to prevent 
fire or an explosion.
• If excessive heat, smoke, or fumes are emitted during battery pack recharging, immediately unplug the battery charger from the power outlet to stop the recharging 
and prevent a fire.
• If the battery pack or back-up battery leaks, changes color, deforms, or emits smoke or fumes, remove it immediately. Be careful not to get burned in the process.
• Prevent any battery leakage from contacting your eyes, skin, and clothing. It can 
cause blindness or skin problems. If the battery leakage contacts your eyes, skin, or 
clothing, flush the affected area with lots of clean water without rubbing it. See a 
physician immediately.
• During the recharging, keep the equipment away from the reach of children. The cord can accidentally choke the child or give an electrical shock.
• Do not leave any cords near a heat source. It can deform the cord or melt the insulation and cause a fire or electrical shock.
• Do not fire the flash at someone driving a car. It may cause an accident.• Do not fire the flash near a person’s eyes. It may impair the person’s vision. When 
using flash to photograph an infant, keep at least 1 meter away.
• Before storing the camera or accessory when not in use, remove the battery pack and disconnect the power plug. This is to prevent electrical shock, heat generation, and 
fire.
• Do not use the equipment where there is flammable gas. This is to prevent an explosion or fire.

• 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.
