FCC STATEMENT
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.
Warning: 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.
FCC Radiation Exposure Statement:
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This
equipment should be installed and operated with minimum distance 20cm between the radiator & your body.
Integration instructions for host product manufacturers according to KDB 996369 D03 OEM
Manual v01
2.2 List of applicable FCC rules
FCC Part 15 Subpart C 15.247 & 15.207 & 15.209
2.3 Specific operational use conditions
Operation Frequency: BLE: 2402~2480MHz
WiFi 2.4G: 2412~2462MHz for 802.11b/g/n(HT20)
Number of Channel: BLE: 40 Channels
WiFi 2.4G: 11 Channels for 802.11b/g/n(HT20)
Modulation Type: BLE: GFSK
WiFi 2.4G: CCK, DQPSK, DBPSK for DSSS;
64QAM, 16QAM, QPSK, BPSK for OFDM
Antenna Type: BLE&WiFi 2.4G: PCB Antenna
Antenna Gain(Peak): BLE/ WiFi 2.4G: 2 dBi (Provided by customer)
The module can be used for mobile or portable applications with a maximum 2dBi antenna. The host
manufacturer installing this module into their product must ensure that the final composit product
complies with the FCC requirements by a technical assessment or evaluation to the FCC rules,
including the transmitter operaition. The host manufacturer has to be aware not to provide information
to the end user regarding how to install or remove this RF module in the user's manual of the end
product which integrates this module. The end user manual shall include all required regulatory
information/warning as show in this manual.
2.4 Limited module procedures
Not applicable. The module is a Single module and complies with the requirement of FCC Part 15.212.

2.5 Trace antenna designs
Not applicable. The module has its own antenna, and doesn’t need a host’s printed board microstrip
trace antenna etc.
2.6 RF exposure considerations
The module must be installed in the host equipment such that at least 20cm is maintained between the
antenna and users’ body; and if RF exposure statement or module layout is changed, then the host
product manufacturer required to take responsibility of the module through a change in FCC ID or new
application. The FCC ID of the module cannot be used on the final product. In these circumstances,
the host manufacturer will be responsible for re-evaluating the end product (including the transmitter)
and obtaining a separate FCC authorization.
2.7 Antennas
Antenna Specification are as follows:
Antenna Type:PCB Antenna
Antenna Gain(Peak):2 dBi (Provided by customer)
This device is intended only for host manufacturers under the following conditions:
The transmitter module may not be co-located with any other transmitter or antenna;
The module shall be only used with the External antenna(s) that has been originally tested and
certified with this module. The antenna must be either permanently attached or employ a ‘unique’
antenna coupler.
As long as the conditions above are met, further transmitter test will not be required. However, the
host manufacturer is still responsible for testing their end-product for any additional compliance
requirements required with this module installed (for example, digital device emissions, PC peripheral
requirements, etc.).

2.8 Label and compliance information
Host product manufacturers need to provide a physical or e-label stating “Contains FCC ID
VYV-TGW206-11P With their finished product.
2.9 Information on test modes and additional testing requirements
Operation Frequency: BLE: 2402~2480MHz
WiFi 2.4G: 2412~2462MHz for 802.11b/g/n(HT20)
Number of Channel: BLE: 40 Channels
WiFi 2.4G: 11 Channels for 802.11b/g/n(HT20)
Modulation Type: BLE: GFSK
WiFi 2.4G: CCK, DQPSK, DBPSK for DSSS;
64QAM, 16QAM, QPSK, BPSK for OFDM
Antenna Type: BLE&WiFi 2.4G: PCB Antenna
Antenna Gain(Peak): BLE/ WiFi 2.4G: 2 dBi (Provided by customer)
Host manufacturer must perfom test of radiated & conducted emission and spurious emission, etc
according to the actual test modes for a stand-alone modular transmitter in a host, as well as for
multiple simultaneously transmitting modules or other transmitters in a host product.
Only when all the test results of test modes comply with FCC requirements, then the end product can
be sold legally.
2.10 Additional testing, Part 15 Subpart B disclaimer
The modular transmitter is only FCC authorized for FCC Part 15 Subpart C 15.247 & 15.207 & 15.209
and that the host product manufacturer is responsible for compliance to any other FCC rules that apply
to the host not covered by the modular transmitter grant of certification. If the grantee markets their
product as being Part 15 Subpart B compliant (when it also contains unintentional-radiator digital
circuity), then the grantee shall provide a notice stating that the final host product still requires Part 15
Subpart B compliance testing with the modular transmitter installed.
