List of applicable FCC rules
FCC Part 15.247
RF exposure considerations
This equipment complies with the FCC RF radiation exposure limits set forth for an 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- ESP32” or “Contains transmitter module FCC ID: 2A54N-ESP32”.
Information on test modes and additional testing requirements
Contact Shenzhen HiLetgo E-Commerce Co., Ltd will provide a 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.
FCC Warning
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.
NOTE 1: Any changes or modifications to this unit not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment.
FCC Radiation Exposure Statement:
This equipment complies with FCC radiation exposure limits set forth for an
uncontrolled environment. End-users must follow the specific operating
instructions for satisfying RF exposure compliance.
Note 1: This module is certified that complies with RF exposure
requirements under mobile or fixed conditions, this module is to be installed
only in mobile or fixed applications.
A mobile device is defined as a transmitting device designed to be used in
other than fixed locations and to generally be used in such a way that a
separation distance of at least 20 centimeters is normally maintained between
the transmitter’s radiating structure(s) and the body of the user or nearby
persons. Transmitting devices designed to be used by consumers or workers that
can be easily re-located, such as wireless devices associated with a personal
computer, are considered to be mobile devices if they meet the 20-centimeter
separation requirement.
A fixed device is defined as a device that is physically secured at one
location and is not able to be easily moved to another location.
Note 2: Any modifications made to the module will void the Grant of
Certification, this module is limited to OEM installation only and must not be
sold to end-users, end-user have no manual instructions to remove or install
the device, only software or operating procedure shall be placed in the end-
user operating manual of final products.
Note 3: The module may be operated only with the antenna with which it is
authorized. Any antenna that is of the same type and of equal or less
directional gain as an antenna that is authorized with the intentional
radiator may be marketed with and used with, that intentional radiator.
Note 4: For all products markets in the US, OEM has to limit the
operation channels in CH1 to CH11 for the 2.4G band by supplied firmware
programming tool. OEM shall not supply any tool or info to the end-user
regarding Regulatory Domain change.
