Operation is subject to the following two conditions: (1) This device may not cause harmful interference. (2) This device must accept any interference received, including interference that may cause undesired operation. 2. Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: Reorient or relocate the receiving antenna. Increase the separation between the equipment and receiver. Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. Consult the dealer or an experienced radio/TV technician for help. SAR Informa tion Statement Your wireles s phone is a radio tran smitter and receiver. It is designed and manufa ctured not to exceed the emission limits for ex posure to radiofreque ncy (RF) energy set b y the Federal Communica tions Commission of th e U.S. Government. Th ese limits are part of c omprehensive guidelines a nd establish permitted l evels of RF energy for t he general population. T he guidelines are based o n standards that were developed by indepen dent scientificorganization s through periodic and thorough evaluation o f scientific studies. The standards include a sub stantial safety margin desig ned to assure the safe ty of all persons, regard less of age and health. The exposure standard fo r wireless mobile phon es employs a unit of measurement know n as the Specific Absorp tion Rate, o r SAR. The SAR limit se t by the FCC is 1.6 W/kg . * Tests for SAR are co nducted with t he phone t ransmitting at its highe st certified power level in all teste d frequency bands. Althou gh the SAR is determined at the high est certified power leve l, the actua l SAR level of the phone while oper ating can b e well belo w the max imum value . This is be cause the p hone is design ed to opera te at multip le power le vels so as to use only t he power re quired toreach the netwo rk. In gener al, the close r you are to a wireless base station antenna, t he lower th e power outpu t. Before a p hone mode l is available for sale to t he public, it must be te sted and cer tified to the FC C that it doe s not exceed the limit established b y the gover nment adopted requirement for safe exposure. The tests are per formed in positions and locations (e.g., at the ear and worn on the body ) as required by the FCC for each model. The highest SAR value for this model phone when tested for use at the ear is 0.35 W/Kg and when worn on the body, as d escribed in this Body-worn Operation This device was tested for typical body-worn operations. To comply with RF exposure requirements, a minimum separation distance of 15mm must be maintained between the user’s body and the handset, including the antenna. Third-party belt-clips, holsters, and similar accessories used by this device should not contain any metallic components. Body-worn accessor…
