VehiclesRadio signals may affect improperly installedor inadequately shielded electronic systems invehicles. For more info, check with themanufacturer of your vehicle or its equipment.Only qualified personnel should install thedevice in a vehicle. Faulty installation may bedangerous and invalidate your warranty.Check regularly that all wireless deviceequipment in your vehicle is mounted andoperating properly. Do not store or carryflammable or explosive materials in the samecompartment as the device, its parts, oraccessories. Do not place your device oraccessories in the air bag deployment area.Potentially explosive environmentsSwitch your device off in potentially explosiveenvironments, such as near petrol pumps.Sparks may cause an explosion or fire resultingin injury or death. Note restrictions in areaswith fuel; chemical plants; or where blastingoperations are in progress. Areas with apotentially explosive environment may not beclearly marked. These usually are areas whereyou are advised to switch your engine off,below deck on boats, chemical transfer orstorage facilities, and where the air containschemicals or particles. Check with themanufacturers of vehicles using liquefiedpetroleum gas (such as propane or butane) ifthis device can be safely used in their vicinity.Certification information (SAR)This mobile device meets guidelines forexposure to radio waves.Your mobile device is a radio transmitter andreceiver. It is designed not to exceed the limitsfor exposure to radio waves recommended byinternational guidelines. These guidelineswere developed by the independent scientificorganisation ICNIRP and include safetymargins designed to assure the protection ofall persons, regardless of age and health.The exposure guidelines for mobile devicesemploy a unit of measurement known as theSpecific Absorption Rate or SAR. The SAR limitstated in the ICNIRP guidelines is 2.0 watts/kilogram (W/kg) averaged over 10 grams oftissue. Tests for SAR are conducted usingstandard operating positions with the devicetransmitting at its highest certified powerlevel in all tested frequency bands. The actualSAR level of an operating device can be belowthe maximum value because the device isdesigned to use only the power required toreach the network. That amount changesdepending on a number of factors such as howclose you are to a network base station.The highest SAR value under the ICNIRPguidelines for use of the device at the ear is0.93 W/kg.Use of device accessories may result indifferent SAR values. SAR values may varydepending on national reporting and testingrequirements and the network band.Additional SAR information may be providedunder product information atwww.nokia.com.51
