FCC Statement
FCC standards: FCC CFR Title 47 Part 15 Subpart C Section 15.247 PCB antenna
with antenna gain 0.49dBi
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
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: ZWY3008X Or Contains FCC ID: ZWY3008X”
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.

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 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 requirementthen the host can be sold legally.
