4. Statement
The NAD has been certified for integration into the host products under the following condition:
• Antenna installation requirement
The antennas for NAD must be installed a minimum separation distance from the human body
- External Antenna (Shark fin type, MIMO1/MIMO2): 200mm
- Internal Antenna (BUA): 200mm
• Co-location restrictions
Any additional transmitter module could not be co-operated with any other antenna except in accordance with
FCC multi-transmitter product procedures.
<FCC>
CAUTION:
Any changes or modifications not expressly approved by the grantee of this device could void the user's
authority to operate the equipment.
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.
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 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.
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: HFS-
QV28NUS ".
RF Exposure warning
This equipment must be installed and operated in accordance with provided instructions and the antenna(s)
used for this transmitter must be installed to provide a separation distance of at least 20 cm from all persons
and must not be co-located or operating in conjunction with any other antenna or transmitter. End-users and
installers must be provide with antenna installation instructions and transmitter operating conditions for
satisfying RF exposure compliance.

Canada, Industry Canada (IC) Notices
This device contains licence-exempt transmitter(s)/receiver(s) that comply with Innovation, Science and
Economic Development Canada’s licence-exempt RSS(s). Operation is subject to the following two
conditions:
1. This device may not cause interference.
2. This device must accept any interference, including interference that may cause undesired
operation of the device.
Canada, avis d'Industry Canada (IC)
Cet appareil contient un ou des émetteurs/récepteurs exempts de licence conformes aux RSS exempts de
licence d'Innovation, Sciences et Développement économique Canada. Le fonctionnement est soumis aux

Radio Frequency (RF) Exposure Information
The radiated output power of the Wireless Device is below the Innovation, Science and Economic
Development Canada (ISED) radio frequency exposure limits. The Wireless Device should be used in such a
manner such that the potential for human contact during normal operation is minimized.
This device has also been evaluated and shown compliant with the IC RF Exposure limits under mobile
exposure conditions. (Antennas are greater than 20cm from a person's body).
Informations concernant l'exposition aux fréquences radio (RF)
La puissance de sortie rayonnée de l'appareil sans fil est inférieure aux limites d'exposition aux
radiofréquences d'Innovation, Sciences et Développement économique Canada (ISDE). L'Appareil sans fil
doit être utilisé de telle manière que le potentiel de contact humain pendant le fonctionnement normal soit
minimisé.
Cet appareil a également été évalué et démontré conforme aux limites d'exposition RF IC dans des conditions
d'exposition mobile. (Les antennes sont à plus de 20 cm du corps d'une personne).
End Product Labeling
The module is labeled with its own ISED Certification number. If the ISED Certification number are not visible
when the module is installed inside another device, then the outside of the device into which the module is
installed must also display a label referring to the enclosed module. In that case, the final end product must be
labeled in a visible area with the following:
Contains IC: 1787B-QV28NUS
L’étiquette d’homologation d’un module d’Innovation, Sciences et Développement économique Canada devra
être posée sur le produit hôte à un endroit bien en vue, en tout temps. En l’absence d’étiquette, le produit hôte
doit porter une étiquette sur laquelle figure le numéro d’homologation du module d’Innovation, Sciences et
Développement économique Canada, précédé du mot « contient », ou d’une formulation similaire allant dans
le même sens et qui va comme suit:
Contient IC: 1787B-QV28NUS est le numéro d’homologation du module.
