Never text while driving. Keep your phone at least 5 mm away from your body while making calls. Small parts may cause choking. Your phone can produce a loud sound. To prevent possible hearing damage, do not listen at high volume levels for long periods. Exercise caution when holding your phone near your ear while the loudspeaker is in use. Avoid contact with anything magnetic. Keep away from pacemakers and other electronic medical devices. Turn off when asked to in hospitals and medical facilities. Turn off when told to on aircraft and at airports. Turn off when near explosive materials or liquids. Dont use at gas stations. Your phone may produce a bright or flashing light. Dont dispose of your phone in fire. Avoid extreme temperatures. Avoid contact with liquids. Keep your phone dry. Do not attempt to disassemble your phone. 7 Only use approved accessories. For pluggable equipment, the socket-outlet shall be installed near the equipment and shall be easily accessible. Dont rely on your phone as a primary device for emergency communications. W/kg and the highest SAR value for 1.6 Specific Absorption Rate (SAR) Your mobile device is a radio transmitter and receiver. It is designed not to exceed the limits for exposure to radio waves recommended by international guidelines. These guidelines were developed by the independent scientific organization ICNIRP and include safety margins designed to assure the protection of all persons, regardless of age and health. The guidelines use a unit of measurement known as Specific Absorption Rate, or SAR. The SAR limit for mobile devices is this device and mm distance. As mobile devices offer a range of functions, they can be used in other positions, such as on the body as described in the user manual**. As SAR is measured utilizing the devices highest transmitting power, the actual SAR of this device while operating is typically below that indicated above. This is due to automatic changes to the power level of the device to ensure it only uses the minimum power required to communicate with the network.
