FCC Caution:Any changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate this equipment. 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, and (2) this device must accept any interference received, including interference that may cause undesired operation. This Product meets the government's requirements for exposure to radio waves. 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 or health. FCC RF Exposure Information and Statement the SAR limit of USA (FCC) is1.6 W/kg averaged over one gram of this Tablet PC (FCC ID: 2A7DX-BV5200PRO) has been tested against this SAR limit. SAR information on this can be viewed on-line at http://www.fcc.gov/oet/ea/fccid/. Please use the device FCC ID number for search. The device has been evaluated to meet general RF exposure requirements. The device can be used in portable exposure conditions without restriction. 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 followingmeasures: -- 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. FCC ID: 2A7DX-BV5200PRO Canadian regulatory statement This device complies with Innovation, Science, and Economic Development Canada licence-exempt RSS standard(s). Operation is subject to the following two conditions: (1) this device may not cause interference, and (2) this device must accept any interference, including interference that may cause undesired operation of the device. /HSUpVHQWDSSDUHLOHVWFRQIRUPHDX[&15Gތ,QQRYDWLRQSciences et Développement économique Canada applicables aux appareils UDGLRH[HPSWVGHOLFHQFH/ތH[SORLWDWLRQHVWDXWRULVpHDX[GHX[ conditions suivantes :  OތDSSDUHLOQHGRLWSDVSURGXLUHGHEURXLOODJHHW  OތXWLOLVDWHXUGHOތDSSDUHLOGRLWDFFHSWHUtout brouillage UDGLRpOHFWULTXHVXELPrPHVLOHEURXLOODJHHVWVXVFHSWLEOHGތHQ compromettre le fonctionnement. SAR Statement: Mobile Phone has been tested and meets applicable limits for radio frequency (RF) exposure. Specific Absorption Rate (SAR) refers to the rate at which the body absorbs RF energy. The SAR limit is 1.6 watts per kilogram in Canada that set the limit averaged over 1 gram of tissue. During testing, Tablet PC (IC: 25768-BV5200PRO) radios are set to their highest transmission levels and placed in positions that simulate uses against the head, with no separation, and when worn or carried against the torso of the body, with 10mm separation. To reduce exposure to RF energy, use a hands-free option, such as the built-in speaker phone, the supplied headphones, or other similar accessories. Cases with metal parts may change the RF performance of the device, including its compliance with RF exposure guidelines, in a manner that has not been tested or certified. Although this device has been tested to determine SAR in each band of operation, not all bands are available in all areas. Bands are dependent on your service provider’s wireless and roaming networks.
