For more info, check withthe manufacturer of your vehicle or its equipment.Only qualified personnel should install the device in a vehicle. Faulty installation may be dangerous and invalidate your warranty.Check regularly that all wireless device equipment in your vehicle is mounted and operating properly. Do not store or carryflammable or explosive materials in the same compartment as the device, its parts, or accessories. Do not place your device oraccessories in the air bag deployment area.Potentially explosive environmentsSwitch your device off in potentially explosive environments, such as near petrol pumps. Sparks may cause an explosion or fireresulting in injury or death. Note restrictions in areas with fuel; chemical plants; or where blasting operations are in progress.Areas with a potentially explosive environment may not be clearly marked. These usually are areas where you are advised toswitch your engine off, below deck on boats, chemical transfer or storage facilities, and where the air contains chemicals orparticles. Check with the manufacturers of vehicles using liquefied petroleum gas (such as propane or butane) if this device canbe safely used in their vicinity.Certification information (SAR)This mobile device meets international guidelines for exposure to radio waves.Your mobile device is a radio transmitter and receiver. It is designed not to exceed the limits for exposure to radio waves (radiofrequency electromagnetic fields), recommended by international guidelines from the independent scientific organizationICNIRP. These guidelines incorporate substantial safety margins assure the protection of all persons regardless of age and health.The exposure guidelines are based on the Specific Absorption Rate (SAR), which is an expression of the amount of radio frequency(RF) power deposited in the head or body when the device is transmitting. The ICNIRP SAR limit for mobile devices is 2.0 W/kgaveraged over 10 grams of tissue.SAR tests are carried out with the device in standard operating positions, transmitting at its highest certified power level, in allits frequency bands. The maximum recorded SAR values for this device are:Maximum SAR value Frequency bands used when MaximumSAR value was recordedWhen held against the head 0.70 W/kg over 10g LTE 2100 and WLAN 5000When operated at a separation distanceof 1.5 centimetres (5/8 inch) from thebody0.57 W/kg over 10g 4-slot GPRS 900 and WLAN 5000This device meets RF exposure guidelines when used against the head or when positioned at least 1.5 centimetres (5/8 inch)away from the body. When a carry case, belt clip or other form of device holder is used for body-worn operation, it should notcontain metal and should provide at least the above stated separation distance from the body.To send data or messages, a good connection to the network is needed. Sending may be delayed until such a connection isavailable. Follow the separation distance instructions until the sending is finished.During general use, the SAR values are usually well below the values stated above. This is because, for purposes of systemefficiency and to minimise interference on the network, the operating power of your mobile is automatically decreased whenfull power is not needed for the call. The lower the power output, the lower the SAR value.© 2013 Nokia. All rights reserved. 111
