Wireless-Tag Technology Co., Ltd. V1.0.0 Federal Communication Commission Statement (FCC, U.S.) This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation.
Wireless-Tag Technology Co., Ltd. V1.0.0 equipment is no longer considered valid and the FCC ID of the module cannot be used on the final product. In these circumstances, the OEM integrator will be responsible for re-evaluating the end product (including the transmitter) and obtaining a separate FCC authorization. End product labeling: The final end product must be labeled in a visible area with the following: “Contains Transmitter Module FCC ID: 2AFOS-WT32S2WROVER”.
Wireless-Tag Technology Co., Ltd. V1.0.0 2.6 RF exposure considerations The module must be installed in the host equipment such that at least 20cm is maintained between the antenna and users’ body; and if RF exposure statement or module layout is changed, then the host product manufacturer required to take responsibility of the module through a change in FCC ID or new application. The FCC ID of the module cannot be used on the final product.
Wireless-Tag Technology Co., Ltd. V1.0.0 Manufacturer's Name: Wireless-Tag Technology Co., Ltd Sample Description: WIFI Module Trade Mark: wireless-tag Model number: WT32-S2-WROVER This device was tested for operations. To comply with RF exposure requirements, a minimum separation distance of 20cm must be maintained between the user’s body and the product, including the antenna . Accessories that do not meet these requirements may not comply with RF exposure requirements and should be avoided.
