17. Warning Statements
<FCC Warning Statements>
FCC Part 15.19 Statements:
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.
FCC Part 15.105 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.
FCC Part 15.21 statement
Any changes or modifications not expressly approved by the party responsible for compliance could void the user's
authority to operate this equipment.
RF Exposure Statement
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. This device must not be co-located or
operating in conjunction with any other antenna or transmitter.
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: 2AKMF-WD-MSO”
“Contains IC: 22266-WDMSO”
RSS-GEN, Sec. 8.4– (licence-exempt radio apparatus)
This device complies with Industry Canada licence-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.
Le présent appareil est conforme aux CNR d’Industrie Canada applicables aux appareils radio exempts de licence.
L’exploitation est autorisée aux deux conditions suivantes :
(1) l’appareil ne doit pas produire de brouillage, et
(2) l’utilisateur de l’appareil doit accepter tout brouillage radioélectrique subi, même si le brouillage est susceptible
d’en compromettre le fonctionnement.
RF Exposure
The antenna (or antennas) must be installed so as to maintain at all times a distance minimum of at least 20 cm
between the radiation source (antenna) and any individual. This device may not be installed or used in conjunction
with any other antenna or transmitter.
l'exposition aux RF
L’antenne (ou les antennes) doit être installée de façon à maintenir à tout instant une distance minimum de au moins
20 cm entre la source de radiation (l’antenne) et toute personne physique.
Étiquetage du produit final (IC)
Le module BT111 est étiqueté avec sa propre identification FCC et son propre 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 présenter une étiquette faisant référence 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 : 2AKMF-WD-MSO
« Contient module émetteur IC : 22266-WDMSO
