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 Part15 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.
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 20cm between the radiator & your body. This transmitter must
not be co-located or operating in conjunction with any other antenna or transmitter. The availability of some specific
channels and/or operational frequency bands are country dependent and are firmware programmed at the factory to match
the intended destination. The firmware setting is not accessible by the end user.
Wireless 5 GHz Band Statements:
As the Access Point can operate in the 5150-5250 MHz frequency band it is limited by the FCC to indoor use only so as
to reduce the potential for harmful interference to co-channel Mobile Satellite systems.
High power radars are allocated as primary users (meaning they have priority) of the 5250-5350 MHz and 5650-5850
MHz bands. These radars could cause interference and /or damage to the access point when used in Canada.
IMPORTANT NOTE:
In the event that these conditions can not be met (for example certain laptop configurations or co-location with another
transmitter), then the FCC authorization is no longer considered valid and the FCC ID can not be used on the final
product. In these circumstances, the OEM integrator will be responsible for re-evaluating the end product (including the

3
transmitter) and obtaining a separate FCC authorization.
End Product Labeling
This transmitter module is authorized only for use in device where the antenna may be installed such that 20 cm may be
maintained between the antenna and users. The final end product must be labeled in a visible area with the following:
“Contains FCC ID: NKR-DCMA86＂.
Manual Information To the End User
The OEM integrator has to be aware not to provide information to the end user regarding how to
install or remove this RF module in the user＇ s manual of the end product which integrates this
module. The end user manual shall include all required regulatory information/warning as show in this manual.
