uncontrolled environment. This equipment should be installed and operated with a minimum

distance of 20cm between the radiator and any part of your body.

Label and compliance information

FCC ID label on the final system must be labeled with “Contains FCC ID:

2A54N-ESP8266” or “Contains transmitter module FCC ID: 2A54N-ESP8266”.

Information on test modes and additional testing requirements

Contact Shenzhen HiLetgo E-Commerce Co., Ltd will provide stand-alone modular

transmitter test mode. Additional testing and certification may be necessary when multiple

modules are used in a host.

Additional testing, Part 15 Subpart B disclaimer

To ensure compliance with all non-transmitter functions the host manufacturer is

responsible for ensuring compliance with the module(s) installed and fully operational. For

example, if a host was previously authorized as an unintentional radiator under the Supplier’s

Declaration of Conformity procedure without a transmitter certified module and a module is

added, the host manufacturer is responsible for ensuring that the after the module is installed

and operational the host continues to be compliant with the Part 15B unintentional radiator

requirements. Since this may depend on the details of how the module is integrated with the

host, Shenzhen HiLetgo E-Commerce Co., Ltd shall provide guidance to the host

manufacturer for compliance with the Part 15B requirements.
