61 Chapter 4 Problem, Meet Solution If only one IP address is provided, then you must have a router capable of sharing the connection, also known as network address translation (NAT ) or “IP masquerading.” For setup information, check the documentation provided with your router or ask the person who set up your network. An AirPort base station can be used to share one IP address among multiple computers. For information about using an AirPort base station, see Help Center (click Help in the menu bar and search for “airport”) or visit the AirPort website at www.apple.com/support/airport. If you can’t resolve the issue using these steps, contact your ISP or network administrator. Problems with Wireless Communication If you have trouble using wireless communication: ÂMake sure the computer or network you are trying to connect to is running and has a wireless access point. ÂMake sure you’ve properly configured the software according to the instructions that came with your base station or access point. ÂMake sure your iMac is within antenna range of the other computer or the network’s access point. Nearby electronic devices or metal structures can interfere with wireless communication and reduce this range. Repositioning or rotating your iMac might improve reception. ÂCheck the Wi-Fi status menu (Z) in the menu bar. Up to four bars appear, indicating signal strength. If the signal strength is weak, try changing your location. ÂSee Help Center (click Help in the menu bar and search for “wi-fi”). Also see the instructions that came with the wireless device for more information.

66Chapter 5 Last, but Not Least For your safety and that of your equipment, follow these rules for handling and cleaning your iMac and for working more comfortably. Keep these instructions handy for reference by you and others. NOTICE: Incorrect storage or use of your computer may void the manufacturer’s warranty. Important Safety Information WARNING: Failure to follow these safety instructions could result in fire, electric shock, or other injury or damage. Proper handling Set up your iMac on a stable work surface. Never push objects into the ventilation openings. Water and wet locations Keep your iMac away from sources of liquid, such as drinks, washbasins, bathtubs, shower stalls, and so on. Protect your iMac from dampness or wet weather, such as rain, snow, and fog. Power The only way to disconnect power completely is to unplug the power cord. Make sure you pull the plug, not the cord. Always unplug the power cord before opening your iMac to install memory.
67 Chapter 5 Last, but Not Least Unplug the power cord (by pulling the plug, not the cord) and disconnect the ethernet cable or phone cord if any of the following conditions exist: ÂYou want to add memory ÂThe power cord or plug becomes frayed or otherwise damaged ÂYou spill something into the case ÂYour iMac is exposed to rain or excess moisture ÂYour iMac has been dropped or the case has been damaged ÂYou suspect that your iMac needs service or repair ÂYou want to clean the case (use only the recommended procedure described on page 71) Important: 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. WARNING: Your AC cord has a three-wire grounding plug (a plug that has a third, grounding pin). This plug fits only a grounded AC outlet. If you are 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 outlet. Do not defeat the purpose of the grounding plug.
68Chapter 5 Last, but Not Least Power specifications: ÂVoltage: 100 to 240 V AC ÂCurrent: 4 A, maximum ÂFrequency: 50 to 60 Hz Hearing damage Permanent hearing loss may occur if earbuds or headphones are used at high volume. Set the volume to a safe level. You can adapt over time to a higher volume of sound that may sound normal but can be damaging to your hearing. If you experience ringing in your ears or muffled speech, stop listening and have your hearing checked. The louder the volume, the less time is required before your hearing could be affected. Hearing experts suggest that to protect your hearing: ÂLimit the amount of time you use earbuds or headphones at high volume. ÂAvoid turning up the volume to block out noisy surroundings. ÂTurn the volume down if you can’t hear people speaking near you.
