REGULATORY INFORMATION
4.1
FCC AND IC COMPLIANCE
● Compliance Statement
This device complies with Part 15 of the FCC Rules, and Industry Canada RSS-210.
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.
● Caution
Any changes or modifications NOT explicitly APPROVED by SAMSUNG ELECTRONICS CO., LTD. could cause
the CLX-NWA20L module to cease to comply with FCC rules part 15 and Industry Canada RSS-210, and thus void
the user's authority to operate the equipment.
● RF-exposure statement
These modular transmitters, CLX-NWA20L, comply with FCC and IC radiation exposure limits set forth for an
uncontrolled environment. The CLX-NWA20L 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 and/or IC authorization is no longer
considered valid and the FCC ID and/or IC certification number 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 and/or IC equipment 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.
REV 0.1
Samsung Electro-Mechanics Proprietary and Confidential
13/14
SWL-2920U Datasheet
● Label and manual requirements for the End Product
For an end product using the CLX-NWA20L there must be a label containing, at least, the following information:
FCC ID and IC certification number for model CLX-NWA20L
This device contains
FCC ID : A3LSWL-2920U
This device contains
IC : 649E-SWL2920U
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 and/or Industry Canada.
Where the CLX-NWA20L will be installed in final products larger than 8cm x 10cm following statements has to be
placed ONTO the device.
"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,
IC certification number, and/or this statement, the FCC ID, IC certification number, 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 operating in conjunction with any other antenna or transmitter."
