Storage at too high or low temperatures will also result in a gradual capacity loss. As a result the operating time of your mobile phone may be considerably reduced, even after a full recharge of the battery. Regardless of this, the battery has been designed and manufactured so that it can be recharged and used for six months after the purchase of your mobile phone. After six months, if the battery is clearly suffering from loss of performance, we recommend that your replace it. Please buy only Siemens original batteries. Care and maintenance Your phone has been designed and manufactured to the highest of standards and should be treated with great care. The suggestions below will help you to enjoy your phone for many years. · Protect your phone from moisture and humidity! Precipitation, humidity and liquids contain minerals that will corrode electronic circuits. Should your phone nonetheless become wet, disconnect it immediately from any power supply, remove the battery and leave the open phone to dry at room temperature! · Do not use or store the phone in dusty, dirty areas. Its moving parts may become damaged. · Do not store your phone in hot areas. High temperatures can shorten the life of electronic devices, damage batteries and warp or melt certain plastics. · Do not store your phone in cold areas. When the phone warms up again (to its normal ambient temperature), moisture can form inside the phone, which may damage electronic circuit boards. · Do not drop, knock or shake your phone. Rough handling can damage internal circuit boards! · Do not use harsh chemicals, cleaning solvents, or strong detergents to clean the phone! The suggestions given above apply equally to your phone, battery, charger and all accessories. If any of these parts are not working properly, take them to your nearest qualified service outlet. The personnel there will assist you and, if necessary, repair the device. 14 SAR - International (ICNIRP) the closer you are to a base station, the lower the power output. The highest SAR value for this model phone when tested for use at the ear is 0.56 W/kg***. SAR information can also be found at www.siemens-mobile.com While there may be differences between the SAR levels of various phones and at various positions, they all meet the international guidelines for safe RF exposure. SAR - International (ICNIRP) INFORMATION ON RF EXPOSURE /SPECIFIC ABSORPTION RATE (SAR) THIS MOBILE PHONE MEETS THE LIMITS FOR PROTECTION OF THE HEALTH OF THE PUBLIC FROM THE EFFECTS OF EXPOSURE TO ELECTROMAGNETIC FIELDS Your mobile phone is a radio transmitter and receiver. It is designed and manufactured not to exceed the limits for exposure to radio frequency (RF) energy recommended by international guidelines from the International Commission on Non-Ionizing Radiation Protection (ICNIRP). These limits are part of comprehensive guidelines for the protection of the public and establish permitted levels of RF energy for the population. The guidelines were confirmed by independent scientific organisations through periodic and thorough evaluation of scientific studies*. The limits include a substantial safety margin designed to assure the safety of all persons, regardless of age and health. The exposure limit for mobile phones employs a unit of measurement known as the Specific Absorption Rate, or SAR. The SAR limit stated in the international guidelines is 2.0 W/kg**. Tests for SAR are conducted in all frequency bands using standard operating positions with the phone transmitting at its highest power level. The actual SAR level of the phone during operation can be well below the maximum value. This is because the phone is designed to operate at multiple power levels so as to use only the power required to reach the network. In general, * The World Health Organization (WHO, CH-1211 Geneva 27, Switzerland) states that present scientific information does not indicate the need for any special precautions for use of mobile phones. Further information: www.who.int/peh-emf, www.mmfai.org, www.siemens-mobile.com ** averaged over 10g of tissue. *** SAR values may vary depending on national requirements and frequency bands. information for different regions can be found at www.siemens-mobile.com Safety precautions 15 Safety precautions Information for parents Please read the operating instructions and safety precautions carefully before use. Explain the content and the hazards associated with using the phone to your children. Remember to comply with legal requirements and local restrictions when using the phone. For example in aeroplanes, petrol stations, hospitals or while driving. Mobile phones can interfere with the functioning of medical devices such as hearing aids or pacemakers. Keep at least 20 cm/9 inches between phone and pacemaker. When using the mobile phone hold it to the ear which is further away from the pacemaker. For more information consult your doctor. Small parts such as the SIM card, sealing stop, lens ring and lens cap can be dismantled and swallowed by small children. The phone must therefore be stored out of the reach of small children. The mains voltage specified on the power supply unit (V) must not be exceeded. Otherwise the charging device may be destroyed. The power supply must be plugged into an easily accessible AC mains power socket when charging the battery. The only way to turn off the charging device after charging the battery is to unplug it. Only use original Siemens batteries (100 % mercury-free) and -charging devices. Otherwise you risk serious damage to health and property. The battery could explode, for instance. Important Please dispose of unwanted batteries and phones as permitted by the laws in your country. The phone may cause interference in the vicinity of TV sets, radios and PCs. Use only Siemens original accessories. This will avoid potential risks to health or property and ensure compliance with all relevant regulations. Improper use will invalidate the guarantee! These safety instructions also apply to Siemens original accessories. The ringtone, info tones and handsfree talking are reproduced through the loudspeaker. Do not hold the phone to your ear when it rings or when you have switched on the handsfree function. Otherwise you risk serious permanent damage to your hearing. You may only open the phone to replace the battery (100 % mercuryfree), faceplate, keypad or SIM card. You must not open the battery under any circumstances. All other changes to this device are strictly prohibited and will invalidate the guarantee. Ref.No.: A31008-H6230-A1-2-7619 *A5B00075490743*
