Caution
Any changes or modifications NOT explicitly APPROVED by Samsung Electronics Co.,
Ltd. could cause the ML-NWA65L(ML-NWA65L/XRX) module to cease to comply with
FCC rules part 15, and thus void the user's authority to operate the equipment.
RF-exposure statement
These modular transmitters, ML-NWA65L(ML-NWA65L/XRX), comply with FCC
radiation exposure limits set forth for an uncontrolled environment. The ML-
NWA65L(ML-NWA65L/XRX) should be installed and operated with minimum distance
20cm between the antenna and the body of the user or nearby persons. 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 users manual of the end product which integrate
this module.
This device is intended only for OEM integrators under the following conditions:
1) The antenna must be installed such that 20 cm is maintained between the antenna
and users, and 2) The transmitter module may not be co-located with any other
transmitter or antenna.
As long as the 2 conditions above are met, further transmitter testing will not be required.
However, the OEM integrator is still responsible for testing their end product for any
additional compliance requirements required with this module installed (for example,
digital device emissions, PC peripheral requirements, etc.).
IMPORTANT NOTE: In the event that these conditions cannot 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 cannot be used on the final
product. In these circumstances, the OEM integrator will be responsible for re-
evaluating the end product (including the transmitter) and obtaining a separate FCC
authorization.
Antenna
These modular transmitters are for OEM integrations only. The end-user product will be
installed in such a manner that only the authorized antennas are used.
Label and manual requirements for the End Product
For an end product using the ML-NWA65L(ML-NWA65L/XRX) there must be a label
containing, at least, the following information:
FCC ID for model ML-NWA65L(ML-NWA65L/XRX)
User Manual
REV 0.1 Samsung Electronics Proprietary and Confidential 14/21
The label must be affixed on an exterior surface of the end product such that it will be
visible upon inspection in compliance with the modular approval guidelines developed
by the FCC.
Where the ML-NWA65L(ML-NWA65L/XRX) will be installed in final products larger than
8cm x 10cm following statements has to be placed ONTO the device.
"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."
In case where the final product will be installed in locations where the end consumer is
not able to see the FCC ID and/or this statement, the FCC ID and the statement shall
also be included in the end-product manual.
The users manual for end users must include the following information in a prominent
location "IMPORTANT NOTE: To comply with FCC RF exposure compliance
requirements, the antenna 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
