WARNING STATEMENTS
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. Referring
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.
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.

Page 4/9 2020/6/15
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 user’s 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 user’s 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 FCC ID:
PPQ-WCBN4606L ". 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 willmaintain 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

Page 5/9 2020/6/15
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
