4. Notice
_ FCC Statement
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 cause undesired
operation.
_ Warning
Any changes or modifications NOT explicitly APPROVED by Samsung Electronics Co.,
Ltd. could cause the WSNFM400A00 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, WSNFM400A00, comply with FCC radiation exposure limits
set forth for an uncontrolled environment. The WSNFM400A00 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 and IC 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).
_ 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.

FCC approval
This device complies with Part 15 of the FCC`s 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 undesirable operation.
To satisfy FCC exterior labeling requirements, the following text must be placed on the exterior of the end product.
Contains Transmitter module FCC ID: A3LWSNFM400A00
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 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.
IC approval
This device complies with Industry 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.
Cet appareil est conforme avec Industrie Canada exempts de licence standard RSS (s). L'opération est soumise aux deux
conditions
suivantes: (1) cet appareil ne peut causer d'interférences, et (2) cet appareil doit accepter toute interférence, y compris les
interférences qui
peuvent causer un mauvais fonctionnement de l'appareil.
The host device must be labeled to display the Industry Canada certification number of the module.
Contains transmitter module IC: 649E-WSNFM400A00
Le dispositif d'accueil doivent être étiquetés pour afficher le numéro de certification d'Industrie Canada du module.
Contient module émetteur IC : 649E-WSNFM400A00
User information
Caution: Any changed or modifications not expressly approved by the party responsible for compliance could void the user`s
authority to operate this equipment.

IMPORTANT NOTE
This device complies with FCC & IC radiation exposure limits set forth for an uncontrolled environment. This device should
be installed and
must not be co-located or operating in conjunction with any other antenna or transmitter.
This device is intended only for OEM integrators under the following conditions:
1) This module may not be co-located with any other transmitters or antennas.
As long as 2 conditions above are met, further transmitter test will not be required. However, the OEM integrator is still
responsible for
testing their end-product for any additional compliance requirements with this module installed.
In the event that these conditions cannot be met, then the FCC & IC authorizations are 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 this
module and obtaining separate FCC & IC authorizations.

NOTE IMPORTANTE
Cet appareil est conforme aux limites de la FCC et IC exposition aux radiations dans un environnement non contrôlé. Cet
appareil doit être
installé et ne doit pas être co-localisées ou opérant en conjonction avec une autre antenne ou un autre émetteur.
Cet appareil est conçu uniquement pour les intégrateurs OEM dans les conditions suivantes :
1) Ce module ne peut pas être co-localisés avec les autres émetteurs ou les antennes.
Aussi longtemps que deux conditions précitées sont remplies, le test du transmetteur supplémentaires ne seront pas tenus.
Toutefois,
l'intégrateur OEM est toujours responsable de tester leurs produits finis pour toutes les exigences de conformité
supplémentaires avec ce
module installé.
Dans le cas où ces conditions ne peuvent pas être remplies, alors la FCC et IC autorisations ne sont plus considérés
comme valides et l'ID
de la FCC ne peut pas être utilisé sur le produit final. Dans ces circonstances, l'intégrateur OEM sera responsable de
réévaluer le produit
final, y compris l'obtention de ce module et séparée de la FCC et IC autorisations
