However, there is no guarantee that interference will not occur in a particularinstallation; if this equipment does cause harmful interference to radio or television reception, which can bedetermined by turning the equipment off and on, the user is encouraged to try to correct the interference by oneor more of the following measures:• Reorient / 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.Specific Absorption Rates (SAR) for Wireless PhonesThe SAR is a value that corresponds to the relative amount of RF energy absorbed in the head of a user of awireless handset.The SAR value of a phone is the result of an extensive testing, measuring and calculation process. It does notrepresent how much RF the phone emits. All phone models are tested at their highest value in strict laboratorysettings. But when in operation, the SAR of a phone can be substantially less than the level reported to theFCC. This is because of a variety of factors including its proximity to a base station antenna, phone design andother factors. What is important to remember is that each phone meets strict federal guidelines. Variations inSARs do not represent a variation in safety.All phones must meet the federal standard, which incorporates a substantial margin of safety. As stated above,variations in SAR values between different model phones do not mean variations in safety. SAR values at orbelow the federal standard of 1.6 W/kg are considered safe for use by the public.The highest reported SAR values of the A847M are:GSM 850: Head: 0.33 W/Kg; Body-worn: 1.38 W/kgGSM 1900: Head: 0.52W/Kg; Body-worn: 0.48 W/kgWCDMA 850: Head: 0.61 W/kg; Body-worn: 0.66W/kgWCDMA1900: Head: 1.1 W/kg; Body-worn: 0.63W/kg
