Qingdao Haier Technology Co., Ltd PCB Antenna minimum clearance area 4、Application reference Please read the following statement before using the WIFI module MK-QTWIFI-11(A)/(B). FCC： 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, and (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. Please notice that 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 FCC ID: 2ALD3-MKQTWIFI08” any similar wording that expresses the same meaning may be used. The module is limited to OEM installation ONLY. The OEM integrator is responsible for ensuring that the end-user has no manual instruction to remove or install module. The module is limited to installation in mobile application; A separate approval is required for all other operating configurations, including portable configurations with respect to Part 2.1093 and difference antenna configurations. The OEM integrator is responsible for ensuring that the host product whichis installed and operating with the module is in compliant with Part 15Bunintentional Radiator requirements, please note that For a Class B digitaldevice or peripheral, the instructions furnished the user manual of theend-user product shall include the following or similar statement, placedin a prominent location in the text of the manual. Note: This equipment has been tested and found to comply with the limitsfor a Class B digital device, pursuant to part 15 of the FCC Rules. Theselimits are designed to provide reasonable protection against harmfulinterference in a residential installation.
