Important safety information for your Mac
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. Your iMac can be damaged if dropped, burned, punctured, or crushed, or if it comes in contact with liquids, oils, and lotions. Don’t use a damaged iMac, such as one with a cracked screen, as it may cause injury.
Liquid exposure. Keep your iMac away from sources of liquid, such as drinks, oils, lotions, washbasins, bathtubs, shower stalls, and so on. Protect your iMac from dampness, humidity, or wet weather, such as rain, snow, and fog.
Power. The only way to turn off power completely is to unplug the power cord. Make sure at least one end of the power cord is within easy reach so that you can unplug your iMac when you need to. Unplug the power cord (by pulling the plug, not the cord) and disconnect all cables if any of the following conditions exists:
You want to add memory (you can replace memory yourself only in the 27-inch iMac).
The power cord or plug becomes frayed or otherwise damaged.
You spill something into the case.
Your iMac is exposed to rain or excess moisture.
Your iMac has been dropped, or the case has been damaged.
You suspect that your iMac needs service or repair.
You want to clean the case (use only the recommended procedure, described later in this document).
Power specifications (21.5-inch model):
Voltage: 100 to 240 V AC
Current: 3 A, maximum
Frequency: 50 to 60 Hz
Power specifications (27-inch model):
Voltage: 100 to 240 V AC
Current: 4 A, maximum
Frequency: 50 to 60 Hz
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. See Sound and Hearing.
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 and service center-replaceable in 21.5-inch models. Disassembling your iMac may damage it or may cause injury to you. If your iMac needs service, is damaged, malfunctions, or comes in contact with liquid, contact Apple or an Apple-authorized repair center, such as an Apple Authorized Service Provider. If you attempt to open your iMac or install items other than memory in 27-inch models, you risk damaging your computer, and 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 location-based information provided 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 applicable laws and regulations in the areas where you are using navigation, 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, go to RF Exposure.
Medical device interference. iMac contains components and radios that emit electromagnetic fields. These electromagnetic fields may interfere with medical devices, such as pacemakers and defibrillators. Consult your physician and medical device manufacturer for information specific to your medical device and whether you need to maintain a safe distance of separation between your medical device and iMac. If you suspect iMac is interfering with your 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 and other atmospheric conditions. Using iMac in any area with a potentially explosive atmosphere may be hazardous—particularly in areas where the air contains high levels of flammable chemicals, vapors, or particles such as grain, dust, or metal powders. Exposing iMac to environments having high concentrations of industrial chemicals, including near evaporating liquified gasses such as helium, may damage or impair iMac functionality.
