Be familiar with the user manual before use. * Do not lend your own phone to others. * If your phone requires After Sales service, cont act our designated customer service center. * If your phone is lost or stolen, report to your service provider immediately. * This product should not be equipped with any separate equipment that may cause a chan ge in its original performance as produc t type is registered. Warning Explosion Area You can use high frequency devices at construction site in order to explode explosive by remote co ntrol. Do not use the phone o r attach the accessories when you are at a gas station, a gas leakage hazardous area, and a ch emical storage or on a deck of a ship. Keep th e phone and the accessories away from inflammable material s because the spark at hazardous area may ca use fire or explosion. (Follow all instru ctions and signals within the area.) Phone and Electronic hardware Turn the phone off at transportation facilities or specific ar ea (e.g. airplane and hospital) where phones are prohibited from being used because it may cause accident or affect electronic medical devi ces. (Follow instructions of each organization.) 2 Electromagnetic wave information Phones transmit and receive high frequency (RF energy) with power on. International organizations have made standards and recom mendations regarding effects of this RF energy on human body. To comply with this standard, use cert ified accessories if you use your phone. If you do not use certified acce ssories, you may not keep safe because you violate electromagnetic wave-related criteria. Using phone while driving Be familiar with related laws while driving. * Keep your eye on driving * Do not use phone for safety while driving. * Stop your car for call, if necessary. Precautions for installation of handsfree Do not install handsfree set at a place where driving is interfer ed, or within the expansion of airbag in a vehicle equipped wi th airbag, or at place where human body may be directly injured. * Note that if dedicated earphones are not used, you cannot hear dial tone. Battery Use If you apply excessive forces with charged batteries in your pocke t or bag, or give a shock with sharp things, the phone may ca use generation of heat, fire or explosion. For further informat ion, refer to’ Precautions for Battery Use’. 3 Safety Rules How to use Antennas Hold your phone in the same way as general phone and do not touch antenna while calling. Because the phone may deteriorate call quality and transmit excessive power. If you change antenna illegally, the phone may be damaged and you cannot be provided wi th service for free. Data-related information While repairing or upgrading the phone, if required, keep importa nt data separately to ensure that data saved in the phone cann ot be cleared. Note that phone manufacturer shall not assume the responsibility for damage due to data loss. Check label for submersion check If phone or battery is waterlogged, label color is changed. Be ca reful in using your phone because you cannot be provided with service for free if the phone is out of order. 4 Information on User’s Safety and Effective Use of Phone * Do not apply excessive forces to assemble charging connecti on of a portable charger – It may cause abnormal charging or damag e. * Do not use damaged power cord or plug, loose outlet – it may cause electric shock or fire. * Do not pull out cord or touch power plug with your hands wet – it may cause electric shock or fire. * Do not bend power cord with excessive force, or make sure the power cord cannot be damaged under heavy materials - it may cau se electric shock or fire. * Do not directly connect + and - terminal outside the charger or battery – It may cause fire or explosion. * Do not charge the battery with unauthorized power (unauthorized generator, illegal charger) - It may cause fire or explosion. * Do not receive or make a call while the phone is being charged (o r with your hands wet) - it may cause electric shock or fire . * Keep the external connector away from baby – it may cause electric shock. * Do not drop charger or battery, or give too much shock – It may cause fire or explosion. * Do not hold the string and swing the phone. You may have yourself or others injured wh en it is slipped out from your hand. 5 How to Use and Manage Phone * Do not disassemble, remodel or repair the phone at random, and contact designated customer serv ice center if the phone requir es repair. * Keep the phone away from infants or pet. It may caus e damage to product, and result in explosion or fire. * Do not turn the phone by holding string, if any. * Do not bend the phone or give any external shock. * Do not sit down with your phone in back pocket. * Keep the phone away from magnetic materials, such as credit card and bankbook. * Keep the phone away from metals in your bag. * Do not put the phone in stove, microwave ov en, heating cooker, and high pressure vessel. * Use the phone within -20°C ~ 50°C, and do not keep the phone at too high or low temperature. * Do not clean the phone with poiso nous chemical or strong detergent. * When using the phone flash, do not use directly for man’ s or animal’s eyes. It may cause damage to eyesight. * Make sure that the phone ring cannot get st uck in the door of bus, subway or car. * If allergy, itch, swell or eczema occurs due to paint or metal of the phone, stop using the phone and see a doctor. * Do not paint the phone. It may cause malfunction, or dama…
