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.
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. This device and its antenna(s) must not be co-located or
operation in conjunction with any other antenna or transmitter.
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 20cm
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 FCC ID:
A3LWLM100A ". 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.
IC Statement
This Class B digital apparatus complies with Canadian ICES-003.
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.
Cet appareil numérique de la classe B est conforme á la norme NMB-003 du Canada.
For product available in the USA/Canada market, only channel 1~11 can be operated.
Selection of other channels is not possible.
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 20cm between the radiator & your body.
This device and its antenna(s) must not be co-located or operation in conjunction with any
other antenna or transmitter.
IMPORTANT NOTE:
This module is intended for OEM integrator. The OEM integrator is still responsible for the IC
compliance requirement of the end product, which integrates this module.
20cm 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 IC RSS-102 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.
LABEL OF THE END PRODUCT: The final end product must be labeled in a visible area with
the following " Contains IC : 649E-WLM100A ".
