Application Scenarios
- Support all kinds of intelligent lamps and sockets
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:
- this device may not cause harmful interference, and
- this device must accept any interference received, including interference that may cause undesired operation.
Any changes or modifications not expressly approved by the party responsible
for compliance could void the user’s authority to operate the equipment.
Please notice that if the FCC identification number is not visible when the
module is installed inside another device, then the outside of the device into
which the module is installed must also display a label referring to the
enclosed module. This exterior label can use wording such as the following:
“Contains FCC ID:2AXJE-LA-WE2S” any similar wording that expresses the same
meaning may be used.
This equipment complies with FCC 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 & your body. This transmitter
must not be co-located or operating in conjunction with any other antenna or
transmitter. The module is limited to OEM installation ONLY.
The OEM integrator is responsible for ensuring that the end-user has no manual
instruction to remove or install module.
A separate approval is required for all other operating configurations,
including portable configurations with respect to Part 2.1093 and difference
antenna configurations.
There is requirement that the grantee provide guidance to the host
manufacturer for compliance with Part 15B requirements.
The OEM integrator is responsible for ensuring that the end-user has no manual
instructions to rem-ove or install module.
