FCC Notice
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 the receiver.
- Connect the equipment to 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.
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 of the device.
Any changes or modifications in construction of this device which are not expressly approved by the
party responsible for compliance could void the user’s authority to operate the equipment.
FCC RF Radiation Exposure Statement
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment.
This transmitter must not be co-located or operating in conjunction with any other antenna or
transmitter.
This equipment should be installed and operated with a minimum distance of 20 cm (7.8 inches) between
the antenna and your body. Users must follow the specific operating instructions for satisfying RF
exposure compliance.

Industry Canada Statement
This device complies with Industry Canada’s applicable licence-exempt RSSs. Operation is subject to the
following two conditions:
(1) This device may not cause interference; and

REMARQUE : LE FABRICANT N’EST PAS RESPONSABLE DES INTERFÉRENCES
RADIOÉLECTRIQUES CAUSÉES PAR DES MODIFICATIONS NON AUTORISÉES APPORTÉES À CET APPAREIL.
DE TELLES MODIFICATIONS POURRAIENT ANNULER L’AUTORISATION ACCORDÉE À L’UTILISATEUR DE
FAIRE FONCTIONNER L’APPAREIL.

OEM Responsibilities to comply with FCC and Industry Canada Regulations
The module has been certified for integration into products only by OEM integrators under the
following condition:
-The antenna(s) must be installed such that a minimum separation distance of at least 20 cm is
maintained between the radiator (antenna) and all persons at all times.
-The transmitter module must not be co-located or operating in conjunction with any other antenna
or transmitter except in accordance with FCC multi-transmitter product procedures.
As long as the two condition above is 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.).
End Product Labeling
The module is labeled with its own FCC ID and IC Certification Number. If the FCC ID and IC
Certification Number are not visible when the module is installed inside another device, then the
outside of the device into which the module is installed must also display a label referring to the
enclosed module. In that case, the final end product must be labeled in a visible area with the
following:
“Contains FCC ID: BEJ-EBR81777301
“Contains IC: 2703N-EBR81777301”
Étiquetagedu produitfinal (IC)
Le module BT111 est étiqueté avec sa proper identification FCC et son proper numéro de
certification IC. Si l’identification FCC et le numéro de certification IC ne sont pas visibles lorsque
le module est installé à l’intérieur d’un autre dispositif, la partie externe du dispositif dans lequel
le module est installé devra également presenter une etiquette faisant reference au module inclus.
Dans ce cas, le produit final devra être étiqueté sur une zone visible avec les informations
suivantes:
« Contient module émetteur identification FCC ID : BEJ-EBR81777301
« Contient module émetteur IC : 2703N-EBR81777301”
