WARNINGS
FCC Statement:
Federal Communication 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 inter fe ren ce in a residenti al in stall at ion. This equipment generates,
uses and can radiate radio frequency energy and, if not installed and used in accordance with
the instructions, may cause harm ful interf eren ce to rad io 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 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 Caution: Any changes or modifications not expressly approved by the party responsible
for
compliance could void the user’s authority to operate this 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.
For product available in the USA/Canada market, only channel 1~11 can be operated.
Selection of other channels is not possible.
This device and its antenna(s) must not be co-located with any other transmit ter s excep t in
accordance with FCC multi-transmitter product procedures.
Refering to the multi-transmitter policy, multiple-transmitter(s) and module(s) can be
operated simultaneously without C2P.
This device is restricted for indoor use.
This device and its antenna(s) must not be co-located or operating in
conjunction with any other antenna or transmitter
Page 9/15
IMPORTANT NOTE:

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 8x10cm, 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.

following FCC part 15.19 statement has to also be available on the label: This device
Page 10/15
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.
IC Statement:
This device contains licence-exempt transmitter(s)/receiver(s) that comply
with Innovation, Science and Economic Development Canada’s
licence-exempt RSS(s). Operation is subject to the following two conditions:
1. This device may not cause interference.
2. This device must accept any interference, including interference that may
cause undesired operation of the device.
L’émetteur/récepteur exempt de licence contenu dans le présent appareil est
conforme aux CNR d’Innovation, Sciences et Développement économique
Canada applicables aux appareils radio exempts de licence. L’exploitation est
autorisée aux deux conditions suivantes :
1. L ’ appar eil ne doi t pas pr oduir e de br oui l lage;
L’appareil doit accepter tout brouillage radioélectrique subi, même si le
brouillage est susceptible d’en compromettre le fonctionnement.
For product available in the USA/Canada market, only channel 1~11 can be operated.
Selection of other channels is not possible.
Pour les produits disponibles aux États-Unis / Canada du marché, seul le canal 1 à 11 peuvent
être exploités. Sélection d'autres canaux n'est pas possible.
This device and its antenna(s) must not be co-located with any other transmitters except in
accordance with IC multi-transmitter product procedures.
Refering to the multi-transmitter policy, multiple-transmitter(s) and module(s) can be
operated simultaneously without reassessment permissive change.
Cet appareil et son antenne (s) ne doit pas être co-localisés ou fonctionnement en association
avec une autre antenne ou transmetteur.
The device for operation in the band 5150–5250 MHz is only for indoor use to reduce the
potential for harmful interference to co-channel mobile satellite systems.
les dispositifs fonctionnant dans la bande 5150-5250 MHz sont réservés uniquement pour une
utilisation à l’intérieur afin de rédui re les risque s de br ouillag e pré jud iciab le aux systèmes de
satellites mobiles utilisant les mêmes canaux.
