Appendix 34 health and safety SAR certification information The device meets international guidelines for exposure to radio waves.   Your phone is a radio transmitter and receiver. It’s designed not to exceed the limits for exposure to radio waves recommended by international guidelines. The guidelines were developed by ICNIRP, an independent technical standards body, and include margins designed to assure the protection of all persons, regardless of age and health. These guidelines use a unit of measurement known as Specific Absorption Rate, (SAR). The SAR limit for mobile devices is 1.6 W/kg and the highest SAR value for this device when tested was1…  Position 850MHz (W/Kg)  1900MHz (W/Kg) Head <2.0 <2.0Body <2.0 <2.0As SAR is measured when the phone is on its highest transmitting power, the actual SAR of this device while operating normally is typically below the levels shown above. This is because your phone automatically changes its power level to ensure it only uses the minimum level required to reach the network. The World Health Organization has stated that present scientific information does not indicate the need for any special precautions for the use of mobile devices.
Appendix 35 important safety information For your own health and safety, please follow the radio frequency (RF) radiation exposure guidelines and keep your phone no less than 1.5cm away from your body. Failure to do this could mean that your RF exposure exceeds the guideline limits. how to limit your radio frequency (RF) exposure The World Health Organization (WHO) gives the following advice to people who want to limit their exposure to RF radiation… Present scientific information does not indicate the need for any special precautions for the use of mobile phones. If individuals are concerned, they may choose to limit their own or their children’s RF exposure by limiting the length of calls, or using ‘hands-free’ devices to keep mobile phones away from the head and body. Further information on the subject can be obtained from the World Health Organization website at http://www.who.int/peh-emf WHO Fact sheet 193: June 2000.
Appendix 36 RegulacionesFCC This mobile phone complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.  This mobile phone has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiated radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: -Reorient or relocate the receiving antenna. -Increase the separation between the equipment and receiver. -Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. -Consult the dealer or an experienced radio/TV technician for help. Changes or modifications not expressly approved by the party responsible for compliance could void the user‘s authority to operate the equipment.
Appendix 37  The antenna(s) used for this transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.  RFExposureInformation(SAR) This mobile phone meets the government’s requirements for exposure to radio waves.  This phone is designed and manufactured not to exceed the emission limits for exposure to radio frequency (RF) energy set by the Federal Communications Commission of the U.S. Government.        The exposure standard for wireless mobile phones employs a unit of measurement known as the Specific Absorption Rate, or SAR. The SAR limit set by the FCC is 1.6W/kg. *Tests for SAR are conducted using standard operating positions accepted by the FCC with the phone transmitting at its highest certified power level in all tested frequency bands. Although the SAR is determined at the highest certified power level, the actual SAR level of the phone while operating 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 poser required to
Appendix 38 reach the network.    In general, the closer you are to a wireless base station antenna, the lower the power output.    The highest SAR value for the model phone as reported to the FCC when tested for use at the ear is 0.617 W/kg and when worn on the body, as described in this user guide, is 0.395 W/kg (Body-worn measurements differ among phone models, depending upon available accessories and FCC requirements.)    While there may be differences between the SAR levels of various phones and at various positions, they all meet the government requirement.    The FCC has granted an Equipment Authorization for this model phone with all reported SAR levels evaluated as in compliance with the FCC RF exposure guidelines. SAR information on this model phone is on file with the FCC and can be found under the Display Grant section of www.fcc.gov/oet/ea/fccid after searching on FCC ID: Q78-UX720. 
Appendix 39  For body worn operation, this phone has been tested and meets the FCC RF exposure guidelines for use with an accessory that contains no metal and the positions the handset a minimum of 1.5 cm from the body.   Use of other accessories may not ensure compliance with FCC RF exposure guidelines.    If you do not use a body-worn accessory and are not holding the phone at the ear, position the handset a minimum of 1.5 cm from your body when the phone is switched on.
