Yourmobile device is a radio transmitter and receiver. It is designed not toexceed the limits for exposure to radio waves recommended by interna-tional guidelines. These guidelines were developed by the independentscientific organization ICNIRP and include safety margins designed toassure the protection of all persons, regardless of age and health.The exposure guidelines for mobile devices employ a unit of measure-ment known as the Specific Absorption Rate or SAR. The SAR limitstated in the ICNIRP guidelines is 2.0 watts/kilogram (W/kg) averagedover 10 grams of tissue. Tests for SAR are conducted using standardoperating positions with the device transmitting at its highest certifiedpower level in all tested frequency bands. The actual SAR level of anoperating device can be below the maximum value because the deviceis designed to use only the power required to reach the network. Thatamount changes depending on a number of factors such as how closeyou are to a network base station.This device meets radio frequency exposure guidelines in the normaluse position at the ear or at least 1.5 centimeter (5/8 inch) away fromthe body. Any carry case, belt clip, or holder for body-worn operationshould not contain metal and should position the device the above-stated distance from your body. To send data files or messages requiresa quality connection to the network. Data files or messages may be de-layed until such a connection is available. Follow the separation distanceinstructions until the transmission is completed.Parts of the device are magnetic. Metallic materials may be attractedto the device. Do not place credit cards or other magnetic storagemedia near the device, because information stored on them may beerased.The surface of this device does not contain nickel in the platings. Thesurface of this device contains stainless steel.NickelFirst time useTo help you take maximum advantage of your phone and services,you may receive messages from Nokia.
