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 3/12
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 i s
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.
Selection of other channels is not possible.
Pour les produits disponibles aux États Uni s / Canada du marché, seul le canal 1 à 11
peuvent être exploités. Sélection d'autres canaux n'est pas possible.
Page 5/12
This device and its antenna(s) must not be co located with any other transmitters except in
accordance with IC multi transmitter product proced ures.
Refering to the multi transmitter policy, multiple transmitter(s) and module(s) can be
operated simultaneously without reassessment permissive change.
Cet appareil et son antenne (s) ne doit pas être co localisés ou fonctionnement en association
avec une autre antenne ou transmetteur.
IMPORTANT NOTE:
IC Radiation Exposure Statement:
This equipment complies with IC RSS 102 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.
Cet équipement est conforme aux limites d'exposition aux rayonnements IC établies pour un
environnement non contrôlé. Cet équipement doit être installé et utilisé avec un minimum de
