Dell 740N, 720N, 760N, 2385P manual

—The product has been dropped or damaged.

—The product does not operate correctly when you follow the operating instructions.

‡Keep your system components away from radiators and heat sources. Also, do not block cooling vents.

‡Do not spill food or liquids on your system components, and never operate the product in a wet environment. If the computer gets wet, see the appropriate chapter in your troubleshooting guide or contact a Dell-authorized service provider.

‡Do not push any objects into the openings of your system components. Doing so can cause fire or electric shock by shorting out interior components.

‡Use the product only with Dell products or other Dell-approved equipment.

‡Allow the product to cool before removing covers or touching internal components.

‡Use the correct external power source. Operate the product only from the type of power source indicated on the electrical ratings label. If you are not sure of the type of power source required, consult your Dell service provider or local power company.

‡To help avoid damaging your system components, be sure the voltage selection switch (if provided) on the power supply is set to match the power available at your location:

—115 volts (V)/60 hertz (Hz) in most of North and South America and some Far Eastern countries such as South Korea and Taiwan

—100 V/50 Hz in eastern Japan and 100 V/60 Hz in western Japan

—230 V/50 Hz in most of Europe, the Middle East, and the Far East

Also be sure that your monitor and attached peripherals are electrically rated to operate with the power available in your location.

‡Use only approved power cable(s). If you have not been provided with a power cable for your computer or storage system or for any AC-powered option intended for your system, purchase a power cable that is approved for use in your country. The power cable must be rated for the product and for the voltage and current marked on the product’s electrical ratings label. The voltage and current rating of the cable should be greater than the ratings marked on the product.

‡To help prevent electric shock, plug the system components and peripheral power cables into properly grounded electrical outlets. These cables are equipped with three-prong plugs to help ensure proper grounding. Do not use adapter plugs or remove the grounding prong from a cable. If you must use an extension cord, use a three-wire cord with properly grounded plugs.

‡Observe extension cord and power strip ratings. Make sure that the total ampere rating of all products plugged into the extension cord or power strip does not exceed 80 percent of the extension cord or power strip ampere ratings limit.
