FCC WARING STATEMENT

FEDERAL COMMUNICATIONS 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 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.

CAUTION:

Any changes or modifications not expressly approved by the party responsible for compliance

could void the user's authority to operate the equipment.

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.

RF exposure warning This equipment complies with FCC RF radiation exposure limits set

forth for an uncontrolled environment. This equipment must be installed and operated in

accordance with provided instructions and must not be co-located or operating in conjunction

with any other antenna or transmitter. End-users and installers must be provided with antenna

installation instructions and transmitter operating conditions for satisfying RF exposure

compliance.

This equipment should be installed and operated with minimum distance 20cm between

the radiator & your body.

This device is restricted to indoor use.

IMPORTANT NOTE:

This module is intended for OEM integrator.

The OEM integrator is still responsible for

1. ensuring that the end-user has no manual instructions to remove or install module

2. the FCC compliance requirement of the end product, which integrates this

module.

3. Appropriate measurements (e.g. 15 B compliance) and if applicable additional

equipment authorizations (e.g. Verification, Doc) of the host device to be

addressed by the integrator/manufacturer.

4. The separate approval is required for all other operating configurations, including

portable configurations with respect to Part 2.1093 and different antenna

configurations

USERS MANUAL OF THE END PRODUCT:

The module is limited to installation in mobile or fixed applications

In the users 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. If the size of

the end product is smaller than the palm of the hand, then additional FCC part 15.19

statement is required to be available in the users manual: This device complies with

Part 15 of 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.

High Power Radars: High power radars are allocated as primary users (meaning they

have priority) in the 5250MHz to 5350MHz and 5650MHz to 5850MHz bands. These

radars could cause interference and/or damage to Wireless LAN devices used in

Canada.

Les utilisateurs de radars de haute puissance sont désignés utilisateurs principaux (c.-à-d.,

qu'ils ont la priorité) pour les bandes 5250 - 5350 MHz et 5650 - 5850 MHz. Ces radars

pourraient causer du brouillage et/ou des dommages aux dispositifs LAN-EL.

IC Radiation Exposure Statement:

This equipment complies with IC RSS-102 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.

Cet équipement est conforme aux limites d’exposition aux rayonnements IC établies

pour un environnement non contrôlé. Cet équipement doit être installé et utilisé avec

un minimum de 20cm de distance entre la source de rayonnement et votre corps
