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. A.2 FCC Statements: 1.This device complies with Part 15 of the FCC rules. Operation is subject to the following two conditions: This device may not cause harmful interference, and This device must accept any interference received, including interference that may cause undesired operation. 2.This device and its antenna(s) must not be co-located or operating in conjunction with any other antenna or transmitter. 3.Changes or modifications to this unit not expressly approved by the party responsible for compliance could void the user authority to operate the equipment. 4.This compliance to FCC radiation exposure limits for an uncontrolled environment, the minimum of 20 cm separation distance shall be maintained between antenna and body. The host device must be labelled to display the FCC ID of the module "Contains FCC ID:X2NBL-LW02-2" If the FCC identification number is not visible when the module is installed inside another device, then the outside of the device into which the module is installed must also display a label referring to the enclosed module. This exterior label can use wording such as the following: “Contains Transmitter Module FCC ID: X2NBL-LW02-2 The modular could be installed or integrated in mobile or fix devices only. This modular could not be installed in any portable device, for example, USB dongle like transmitters is forbidden. when the module is installed inside another device, the user manual of this device must contain below warning statements; 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

Limit Modular approval letter We B-LINK ELECTRONIC LIMITED wishes to request a limited modular transmitter approval (LMA). Our module Product name: wifi module Model number: BL-LW02-2 was deemed to fill the requirements of PART 15 UNLICENSED LIMITED MODULAR TRANSMITTER APPROVAL. 1. The modular transmitter has its own RF shielding, but only have single-sided shielding, see the external photo. We declare that the shielding of the module is identical to the sample tested on batch production. 2. The modular transmitter has buffered modulation/data inputs and the module complies with Part 15 requirements under conditions of excessive data rates or over-modulation. 3. The modular transmitter has its own power supply regulation. 4. The modular transmitter complies with the antenna requirements of Section 15.203 and 15.204(c). The antenna is permanently attached 5. The modular transmitter was tested in a stand-alone configuration. The module was not inside another device during testing. The module is capable of complying with Part 15 emission limits regardless of the device into which it is eventually installed. DC power lines and data input/output lines connected to the module do not contain ferrites. Any accessories, peripherals, or support equipment connected to the module during testing are unmodified or commercially available. 6. The outside of the device into which the module is installed displays a label referring to the enclosed module. This exterior label use wording as following: “Contains FCC ID: XZNBL-LW02-2.” Modular has own permanent attached Label which exhibits FCC ID XZNBL-LW02-2. 7. The modular transmitter complies with any specific rule or operating requirements applicable to the transmitter and we have provided adequate instructions along with the module to explain any such requirements. A copy of these instructions was included in the application for equipment authorization. 8. The modular transmitter complies with the applicable RF exposure requirement, and meet MPE calculation of 47 CFR 1.107(b) (1). A minimum separation distance of 20 cm is always maintained between the modular and it’s antenna with any human being nearby. Signature of applicant: Date: December 29, 2011
