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. This
equipment generates, usesand can radiate radio frequency energy and, if not installed and used inaccordance with the instructions,
