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.
Note: This product 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 product 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 product 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.
Please take attention that changes or modification not expressly approved by the party
responsible for compliance could void the user’s authority to operate the equipment.
This equipment complies with FCC &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.
2.2 List of applicable FCC rules
FCC Part 15.247
2.6 RF exposure considerations
This equipment complies with the FCC RF radiation exposure limits set forth for an uncontrolled
environment. This equipment should be installed and operated with a minimum distance of 20cm
between the radiator and any part of your body.
2.8 Label and compliance information
FCC ID label on the final system must be labeled with “Contains FCC ID:
2ATEV-BL3390-I” or “Contains transmitter module FCC ID: 2ATEV-BL3390-I”.
2.9 Information on test modes and additional testing requirements
Contact Hangzhou BroadLink Technology Co., Ltd. will provide stand-alone modular transmitter
test mode. Additional testing and certification may be necessary when multiple modules are used
in a host.
2.10 Additional testing, Part 15 Subpart B disclaimer
To ensure compliance with all non-transmitter functions the host manufacturer is
responsible for ensuring compliance with the module(s) installed and fully operational. For
example, if a host was previously authorized as an unintentional radiator under the Supplier’s
Declaration of Conformity procedure without a transmitter certified module and a module is
added, the host manufacturer is responsible for ensuring that the after the module is installed
and operational the host continues to be compliant with the Part 15B unintentional radiator
requirements. Since this may depend on the details of how the module is integrated with the
host, Hangzhou BroadLink Technology Co., Ltd.shall provide guidance to the host manufacturer
for compliance with the Part 15B requirements.
Note 1: This module certified that complies with RF exposure requirement under mobile or fixed
condition, this module is to be installed only in mobile or fixed applications.
A separate approval is required for all other operating configurations, including portable
configurations with respect to Part 2.1093 and difference antenna configurations.
This transmitter must not be co-located or operating in conjunction with any other antenna or
transmitter.
Note 2: Any modifications made to the module will void the Grant of Certification, this module is
limited to OEM installation only and must not be sold to end-users, end-user has no manual
instructions to remove or install the device, only software or operating procedure shall be placed
in the end-user operating manual of final products.
Note 3: Additional testing and certification may be necessary when multiple modules are used.
Note 4: The module may be operated only with the antenna with which it is authorized. Any
antenna that is of the same type and of equal or less directional gain as an antenna that is
authorized with the intentional radiator may be marketed with, and used with, that intentional
radiator.
This product must be professionally installed to ensure that no antenna other than that
furnished by the responsible party shall be used with the device
- 16 -
- 17 -
This device and its antenna(s) must not be co-located with any other transmitters except in
accordance with IC multi-transmitter product procedures. Referring to the multi-transmitter
policy, multiple-transmitter(s) and module(s) can be operated simultaneously without
reassessment permissive change.
The host product shall be properly labelled to identify the modules within the host product.
The ISED certification label of a module shall be clearly visible at all times when installed in the
host product; otherwise, the host product must be labelled to display the ISED certification
number for the module, preceded by the word "contains" or similar wording expressing the same
meaning, as follows:
Contains IC: 25062-BL3390I
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
radioexempts 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.
Under Industry Canada regulations, this radio transmitter may only operate using an
antenna of a type and maximum (or lesser) gain approved for the transmitter by
Industry Canada. To reduce potential radio interference to other users, the antenna
type and its gain should be so chosen that the equivalent isotropically radiated power
(e.i.r.p.) is not more than that necessary for successful communication.
Conformément à la réglementation d'Industrie Canada, le présent émetteur radio
peut fonctionner avec une antenne d'un type et d'un gain maximal (ou inférieur)
approuvé pour l'émetteur par Industrie Canada. Dans le but de réduire les risques de
brouillage radioélectrique à l'intention des autres utilisateurs, il faut choisir le type
d'antenne et son gain de sorte que la puissance isotrope rayonnée équivalente
(p.i.r.e.) ne dépasse pas l'intensité nécessaire à l'établissement d'une communication
satisfaisante.
This equipment complies with FCC/IC RSS-102 radiation exposure limits set forth
for an uncontrolled environment. This eqipment should be installed and operated
with minimum distance 20cm between the radiator & your body.
