Radiation Exposure Statement:

This equipment complies with FCC radiation exposure limits set forth for an uncontrolled
environment.

This transmitter must not be co-located or operating in conjunction with any other antenna
or transmitter.

The availability of some specific channels and/or operational frequency bands is country
dependent and firmware programmed at the factory to match the intended destination.

The firmware setting is not accessible by the end user.

The final end product must be labeled in a visible area with the following:

"Contains Transmitter Module 2ANDL-WRD2L"

This radio module must not be installed to co-locate and operating simultaneously with
other radios in host system, additional testing and equipment authorization may be
required to operating simultaneously with other radio.

Declaration of Conformity European notice

Hereby, Hangzhou Tuya Information Technology Co., Ltd. declares that this Wi-Fi module
product is in compliance with essential requirements and other relevant provisions of
Directive 2014/53/EC. A copy of the Declaration of conformity can be found at
