Changes or m odifications to this equipment may cause harmful interference unless the modifications are expressly approved in the instruction manual. The user could lose the authority to operate t his equipment if an unauthorized change or modification is made. U.S. Regulatory Wireless Notice This products emits radio frequency energy, but the radiated output power of this device is far below the FCC radio frequency exposure limits. Nevertheless, the device should be used in such a manner that the potential for human contact with the antenna during normal oper ation is minimized. FCC Radiation Exposure Statement This equipment compiles with FCC radiation exposure limits set forth an uncontrolled enviro nment. This equipment should be installed and operated with minimum distance 20cm between the radiator and your body. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. Federal Communications Commission (FCC) Statement You are cautioned that changes or modifications not expressly approved by the part respon sible for compliance could void the user’s authority to operate the equipment. This equipment has been tested and found to comply with the limits for a class B digital de vice, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable p rotection 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 to radio communications. However, there is no guarantee that interference will not occur in a p articular 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 encou raged 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. End Product Labeling The modular transmitter must be labeled with its own FCC ID number, and, if the FCC ID is not visible when the module is installed inside another device, then the outside of the devic e into which the module is installed must also display a label referring to the enclosed mod ule. This exterior label can use wording such as the following: “Contains Transmitter Module FCC ID: BEJPCRCUDT2” or “Contains FCC ID: BEJPCRCUDT2.” Any similar wording that expres ses the same meaning may be used. The Grantee may either provide such a label, an examp le of which must be included in the application for equipment authorization, or, must provid e adequate instructions along with the module which explain this requirement. In the latter case, a copy of these instructions must be included in the application for equipment authori zation. 8.2 IC (Certification) This device complies with RSS-210 of the Industry Canada Rules.
