Important safety information

WARNING:

Failure to follow these safety instructions could result in fire, electric shock, or other injuries, or damage to your iMac or other property. Read all safety information below before using your iMac.

Handling. Set up your iMac on a hard, stable work surface that allows for adequate air circulation under and around the computer. Never push objects into the ventilation openings.

WARNING:

Your AC cord has a three-wire grounding plug (a plug that has a grounding pin).

This plug fits only a grounded AC outlet. If you’re unable to insert the plug into an outlet because the outlet isn’t grounded, contact a licensed electrician to replace the outlet with a properly grounded one. Do not defeat the purpose of the grounding pin.

Hearing loss. Listening to sound at high volumes may damage your hearing. Background noise, as well as continued exposure to high volume levels, can make sounds seem quieter than they actually are. Use only compatible earbuds, headphones, or earpieces with your iMac. Turn on the audio and check the volume before inserting anything into your ear. For more information about hearing loss, see www.apple.com/sound .

WARNING:

To prevent possible hearing damage, do not listen at high volume levels for long periods.

Repairing. Your iMac doesn’t have any user-serviceable parts, except for the memory, which is user-replaceable in 27-inch models only. Do not attempt to replace or repair any components inside your iMac. If your iMac needs service, contact Apple or an Apple Authorized Service

Provider. If you open your iMac or install items other than memory in 27-inch models, you risk damaging your computer. Such damage isn’t covered by the limited warranty on your iMac.

Navigation. Maps, directions, and location-based apps depend on data services. These data services are subject to change and may not be available in all areas, resulting in maps, directions, or location-based information that may be unavailable, inaccurate, or incomplete. Compare the information provided on iMac to your surroundings and defer to posted signs to resolve any discrepancies. Do not use these services while performing activities that require your full attention. Always comply with posted signs and the laws and regulations in the areas where you are using iMac and always use common sense.

Radio frequency exposure. iMac uses radio signals to connect to wireless networks. For information about radio frequency (RF) energy resulting from radio signals and steps you can take to minimize exposure, see www.apple.com/legal/rfexposure .

Medical device interference. iMac contains components and radios that emit electromagnetic fields, which may interfere with pacemakers, defibrillators, or other medical devices. Maintain a safe distance of separation between your medical device and iMac. Consult your physician and medical device manufacturer for information specific to your medical device. If you suspect iMac is interfering with your pacemaker or any other medical device, stop using iMac.

Medical conditions. If you have a medical condition that you believe could be affected by using iMac (for example, seizures, blackouts, eyestrain, or headaches), consult with your physician prior to using iMac.

Repetitive motion. When you perform repetitive activities such as typing or playing games on iMac, you may experience discomfort in your hands, arms, wrists, shoulders, neck, or other parts of your body. If you experience discomfort, stop using iMac and consult a physician.

High-consequence activities. iMac is not intended for use where the failure of the computer could lead to death, personal injury, or severe environmental damage.

Explosive atmospheres. Charging or using iMac in any area with a potentially explosive atmosphere, such as areas where the air contains high levels of flammable chemicals, vapors, or particles (such as grain, dust, or metal powders), may be hazardous. Obey all signs and instructions.
