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 of the following measures:

• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and the 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.

Caution THE GRANTEE IS NOT RESPONSIBLE FOR ANY CHANGES OR MODIFICATIONS NOT EXPRESSLY APPROVED BY THE PARTY RESPONSIBLE FOR COMPLIANCE. SUCH MODIFICATIONS COULD VOID TH E USER’S AUTHORITY TO OPERATE THE EQUIPMENT.

IMPORTANT NOTE: FCC RF Radiation Exposure Statement This equipment complies with FCC RF radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with a minimum distance of 20 centimeters between the radiator and your body. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.
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 of the device.

A label must be affixed to the outside of the host product with the following statements:
Product Name: Wi-Fi CAT (Connected Appliance Transceiver) Module
Contains FCC ID: 2AFWN-CM01WTA11M

Module is limited to OEM installation ONLY.

• The OEM integrator is responsible for ensuring that the end user has no manual instructions to remove or install module.
• That module is limited to installation in mobile or fixed applications, according to Part 2.1091(b).
• That separate approval is required for all other operating configurations, including portable configurations with respect to Part 2.1093 and different antenna configurations.
