FCC Statement
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.
Any Changes or modifications not expressly approved by the party responsible for compliance could void the user's
authority to operate the equipment.
Note: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part
15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a
residential installation. This equipment generates, uses and can radiate radio
used in accordance with the instructions, may cause harmful interference to radio communications. However, there is
no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful
interference to radio or television reception, which can be determined by turning the equipment off and on, the user is
encouraged to try to correct the interference by one or more of the following measures:
—Reorient or relocate the receiving antenna.
—Increase the separation between the equipment and receiver.
—Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
—Consult the dealer or an experienced radio/TV technician for help.
FCC Radiation Exposure Statement
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.
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: BRWWACO1T Or
Contains FCC ID: BRWWACO1T”
When the module is installed inside another device, the user manual of the host must contain below warning
statements;
1. 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.
(2) This device must accept any interference received, including interference that may cause undesired operation.
Note: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part
15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a
residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and
used in accordance with the instructions, may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause
harmful interference to radio or television reception, which can be determined by turning the equipment off
and on, the user is encouraged to try to correct the interference by one or more of the following measures:

Changes or modifications not expressly approved by the party responsible for compliance could void the user's
authority to operate the equipment.
The devices must be installed and used in strict accordance with the manufacturer's instructions as described in the user
documentation that comes with the product.
Any company of the host device which install this modular with limit modular approval should perform the test of
radiated & conducted emission and spurious emission,etc. according to FCC part 15C : 15.249 and 15.209 &
15.207 ,15B Class B requirement, Only if the test result comply with FCC part 15C : 15.249 and 15.209 &
15.207 ,15B Class B requirement，then the host can be sold legally.
