FCC Regulations:
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.
This device 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 radiated 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.
Caution: Changes or modifications not expressly approved by the party responsible
for compliance could void the user‘s authority to operate the equipment.
RF Exposure Information
This device complies with FCC radiation exposure limits set forth for an uncontrolled
environment. In order to avoid the possibility of exceeding the FCC radio frequency
exposure limits, human proximity to the antenna shall not be less than 20cm (8
inches) during normal operation.
Standalone Condition:
。8 dBi in 700 MHz Band
。5 dBi in 1700 MHz Band
。5 dBi in 1900 MHz Band
Assuming collocated with a WLAN transmitter with maximum 20 dBm average EIRP power

。4 dBi in 1900 MHz Band
ISED Notice
This device complies with Innovation, Science and Economic Development
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 Innovation, Sciences et Développement
économique 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

Label:
CAN ICES-3 (B)/NMB-3(B)
This Class B digital apparatus complies with Canadian ICES-003.
Cet appareil numérique de la classe B est conforme à la norme NMB-003 du Canada.
ISED Radiation Exposure Statement
This device complies with RSS-102 radiation exposure limits set forth for an
uncontrolled environment. In order to avoid the possibility of exceeding the ISED
radio frequency exposure limits, human proximity to the antenna shall not be less
than 20cm (8 inches) during normal operation.
Cet appareil est conforme aux limites d'exposition aux rayonnements de la CNR-102
définies pour un environnement non contrôlé. Afin d'éviter la possibilité de dépasser
les limites d'exposition aux fréquences radio de la CNR-102, la proximité humaine à
l'antenne ne doit pas être inférieure à 20 cm (8 pouces) pendant le fonctionnement
normal.

IMPORTANT NOTE:
This module is intended for OEM integrator. The OEM integrator is still responsible
for the FCC 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
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 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
Transmitter Module FCC ID: NKRIMA2A". 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.
The Innovation, Science and Economic Development Canada certification label of a
module shall be clearly visible at all times when installed in the host device;
otherwise, the host device must be labeled to display the Innovation, Science and
Economic Development Canada certification number for the module, preceded by the
words “Contains transmitter module IC:4441A-IMA2A”.
