SAR Value  W/kg@1g(Head) W/kg@1g(Body)  Use cell phone when the signal strength is good. Keep your calls short or instead use headset or send a text message. This advice applies especially to children, adolescents and pregnant women.  If you are using a Bluetooth headset device, please make sure it has a low power emitter. ROHS Declaration Declaration of Conformity with the requirements of the e-waste Management Rules, 2011 (adopted by Notification S.O.1035 (E) of Ministry of Environment and Forests)  The Product is in conformity with the requirements of Rule 13 of the e-waste Rules. The content of hazardous substance with the exemption of the applications listed in SCHEDULE II of the e-waste Rules: a. Lead (Pb) – not over 0.1% by weight; b. Cadmium (Cd) – not over 0.01% by weight; c. Mercury (Hg) – not over 0.1% by weight; d. Hexavalent chromium (Cr6+) – not over 0.1% by weight; e. Polybrominated biphenyls (PBBs) – not over 0.1% by weight; f. Polybrominateddiphenyl ethers (PBDEs) – not over 0.1% by weight. 1.2 Using your phone safely On The Road Using a phone while driving is illegal in many countries. Please follow local laws and drive safely at all times. Near Sensitive Electronics Don‟t use your phone near sensitive electronic equipment – particularly medical devices such as pacemakers – as it could cause them to malfunction. It can also interfere with the operation of fire detectors and other automatic-control equipment. -5- For more information about how your phone affects pacemakers or other electronic equipment, please contact the manufacturer or your local distributor. Your phone may cause interference when used near TVs, radios or automated office equipment. While Flying Your phone can cause interference with aircraft equipment. So it‟s essential you follow airline regulations. And if airline personnel ask you to switch off your phone, or disable its wireless functions, please do as they say. In Hospital Your phone may interfere with the normal operation of medical equipment. Follow all hospital regulations and turn it off when you‟re asked to by posted warnings or medical staff. At a Petrol Station Don‟t use your phone at petrol stations. In fact, it‟s always best to switch off whenever you‟re near fuels, chemicals or explosives. Around Water Keep your phone away from water (or any other liquid). It‟s not a waterproof model. Making Repairs Never take your phone apart. Please leave that to the professionals. Unauthorised repairs could break the terms of your warranty. Broken Antenna Don‟t use your phone if the antenna is damaged, as it could cause injury. Around Children Keep your mobile out of children‟s reach. It should never be used as a toy and it might not -6- be good for their health. Original Accessories Only use the original accessories supplied with your phone or those approved by the manufacturer. Using unapproved accessories may affect performance, make the warranty void, break national regulations on the use of mobile phones, or even cause injury. Near Explosives Turn off your phone in or near areas where explosive materials are used. Always obey local laws and turn off your phone when requested. Emergency Calls To make an emergency call your phone must be turned on and in an area where there‟s network coverage. Dial the national emergency number and press „send‟. Explain exactly where you are and don‟t hang up until help has arrived. Working Temperature The working temperature for the phone is between 0 Degree and 40 Degree Celcius. Please don‟t use the phone outside the range. Using the phone under too high or too low temperature might cause …
