Regulatory Information
The devices must be installed and used in strict accordance with the instructions as described in
the user documentation that comes with the product.
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 Transmitter Module FCC ID: A5LRTL8188EUS”
When the module is installed inside another device, the user manual of this device must contain
below warning statements:
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.
Changes or modifications not expressly approved by the party responsible for compliance could
void the user's authority to operate the equipment.
This modular could be installed in the fix or mobile devices only, installed in the portable device,
like USB dongle is forbidden. This modular complies with FCC RF 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. This modular must be installed and operated
with a minimum distance of 20 cm between the radiator and user body.
For manufacturer:
The end product into which the module will be installed should be the fix or mobile devices only,
the portable device, like USB dongle is forbidden.
The end product into which the module will be installed should be installed and operated with a
minimum distance of 20 cm between the radiator and user body.
