F52 User Manual 1 / 12 F52 User Manual F52 User Manual 2 / 12 FCC Statement 1. This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference. (2) This device must accept any interference received, including interference that may cause undesired operation. 2. Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. NOTE: This equipment 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 radiate 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. SAR Information Statement Your mobile phone is a radio transmitter and receiver. It is designed and manufactured not to exceed the emission limits for exposure to radiofrequency (RF) energy set by the Federal Communications Commission of the U.S. Government. These limits are part of comprehensive guidelines and establish permitted levels of RF energy for the general population. The guidelines are based on standards that were developed by independent scientific organizations through periodic and thorough evaluation of scientific studies. The standards include a substantial safety margin designed to assure the safety of all persons, regardless of age and health. 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 1.6 W/kg. * Tests for SAR are conducted 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 power required to reach the network. In general, the closer you are to a wireless base station antenna, the lower the power output. Before a phone model is available for sale to the public, it must be tested and certified to the FCC that it does not exceed the limit established by the government adopted requirement for safe exposure. The tests are performed in positions and locations (e.g., at the ear and worn on the body) as required by the FCC for each model. The highest SAR value for this model phone when tested for use on the head is 0.43 W/Kg and when worn on the body, as described in this user guide, is 0.73 W/Kg (Body-worn measurements differ among phone models, depending upon available accessories and FCC requirements). The maximum scaled SAR in hotspot mode is 0.77 W/Kg. While there may be differences between the SAR levels of various phones and at various positions, they all meet the government requirement for safe exposure. 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 http://www.fcc.gov/oet/fccid after searching on FCC ID: 2A6B4-FIGF52 Additional information on Specific Absorption Rates (SAR) can be found on the Cellular Telecommunications Industry Association (CTIA) web-site at http://www.wow-com.com. * In the United States and Canada, the SAR limit for mobile phones used by the public is 1.6 watts/kg (W/kg) averaged over one gram of tissue. The standard incorporates a substantial margin of safety to give F52 User Manual 3 / 12 additional protection for the public and to account for any variations in measurements. The SAR test distance is 10mm. Warnings Please follow these simple guidelines to avoid some untoward incidents. Failure to do these may be dangerous or illegal. TURN ON SAFELY Do not turn on the phone in areas where it is prohibited or when it may cause interference and danger. ROAD SAFETY Obey all road safety laws. Avoid using phone and concentrate on driving instead. INTERFERENCE All wireless phones may be sensitive to interference, which may affect its performance. TURN OFF IN HOSPITALS Follow all restrictions. Turn off the phone near medical equipment. TURN OFF ON AIRCRAFTS Put off the phone before boarding. Wireless devices can cause interference on aircrafts. TURN OFF WHEN REFUELING Do not use the phone near refueling stations or combustible chemicals. USE SENSIBLY Only qualified personnel may install or repair this product. ENHANCEMENTS AND BATTERIES Use only appropriate battery. Do not use non-authorized batteries as it may damage the phone. WATER-RESISTANCE Your phone is not water-resistant. Keep it dry. BACKUP COPIES It is advisable for you to back-up copies or keep a written record of all important information stored in your phone. CONNECTING TO OTHER DEVICES When connecting to any external device, read its user’s guide for detailed and safety instructions. Do not connect with incompatible products.
