FCC Statement: 
Federal Communication Commission Interference Statement 
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 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 Caution: Any changes or modifications not expressly approved by the party responsible 
for compliance could void the user’s authority to operate this equipment. 
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. 
For product available in the USA/Canada market, only channel 1~11 can be operated. 
Selection of other channels is not possible. 
This device and its antenna(s) must not be co•located with any other transmitters except in 
accordance with FCC multi•transmitter product procedures. 
Refering to the multi•transmitter policy, multiple•transmitter(s) and module(s) can be 
operated simultaneously without C2PC. 
 IMPORTANT NOTE: 
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 20 cm 
between the radiator & your body. 

Page 4/12
IMPORTANT NOTE: 
This module is intended for OEM integrator. The OEM integrator is responsible for the 
compliance to all the rules that apply to the product into which this certified RF module is 
integrated. 
Additional testing and certification may be necessary when multiple modules are used. 
20 cm minimum distance has to be able to be maintained between the antenna and the users 
for the host this module is integrated into. Under such configuration, the FCC radiation 
exposure limits set forth for an population/uncontrolled environment can be satisfied. 
Any changes or modifications not expressly approved by the manufacturer could void the 
user's authority to operate this equipment. 
 USERS MANUAL OF THE END PRODUCT: 
In the users manual of the end product, the end user has to be informed to keep at least 20 cm 
separation with the antenna while this end product is installed and operated. The end user has 
to be informed that the FCC radio•frequency exposure guidelines for an uncontrolled 
environment can be satisfied. The end user has to also be informed that any changes or 
modifications not expressly approved by the 
manufacturer could void the user's authority to operate this equipment. If the size of the end 
product is smaller than 8x10cm, then additional FCC part 15.19 statement is required to be 
available in the users manual: This device complies with Part 15 of 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. 
 LABEL OF THE END PRODUCT: 
The final end product must be labeled in a visible area with the following " Contains TX FCC 
ID: AK8WN4645R ". If the size of the end product is larger than 8x10cm, then the following 
FCC part 15.19 statement has to also be available on the label: This device complies with Part 
15 of 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.

OEM Integrator Checklist 
The party below will implement the LITE-ON Module in host systems in accordance with the 
instructions specified in this document and the documents referenced herein. 
1. The OEM integrator will ensure the Module is integrated in a host systems using only the 
approved antenna model(s) described in this document. 
2. The OEM integrator will ensure the antenna placement inside the host system will maintain 
the required spacing to end user for RF Exposure compliance, as specified in this 
document. 
3. If other radios are integrated inside the host with the LITE-ON Module, the OEM integrator 
will contact its test lab, TCB or LITE-ON to determine if additional FCC compliance 
evaluation is required to meet FCC collocation rules. 
4. The OEM integrator will ensure end user documentation will contain the specified 
regulatory wording and ensure the host system and the Module itself are labeled as 
specified in this document. 
5. The OEM integrator will ensure the Module is programmed in the factory with compliant 
transmit power not exceeding the levels specified in this document. 
LITE-ON requests that the OEM integrator acknowledge its receipt of this document and the 
above instructions. You may contact LITE-ON with any questions concerning this document 
or the responsibilities of the OEM integrator. 
IC Statement: 
This device complies with Industry Canada license exempt RSS standard(s). Operation is 
subject to the following two conditions: (1) this device may not cause interference, and (2) 
this device must accept any interference, including interference that may cause undesired 
operation of the device. 
Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils radio 
exempts de licence. L'exploitation est autorisée aux deux conditions suivantes : (1) l'appareil 
ne doit pas produire de brouillage, et (2) l'utilisateur de l'appareil doit accepter tout brouillage 
radioélectrique subi, même si le brouillage est susceptible d'en compromettre le 
fonctionnement. 
For product available in the USA/Canada market, only channel 1~11 can be operated.
