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:
—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.
We will retain control over the final installation of the modular such that compliance of the end product is
assured. In such cases, an operating condition on the limit modular approval for the module must be only
approved for use when installed in devices produced by a specific manufacturer. If any hardware modify or
RF control software modify will be made by host manufacturer,C2PC or new certificate should be apply to
get approval,if those change and modification made by host manufacturer not expressly approved by the
party responsible for compliance ,then it is illegal.
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:
2ABN2-RSBRS02ABR Or Contains FCC ID: 2ABN2-RSBRS02ABR”
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:
—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.
2. 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 : 15.247 and
15.209 & 15.207 ,15B Class B requirement, Only if the test result comply with FCC part 15C : 15.247 and
15.209 & 15.207 ,15B Class B requirement，then the host can be sold legally.
