FCC approval
This device complies with Part 15 of the FCC`s Rules. Operation is subject to the following two conditions:
- This device may not cause harmful interference, and
- This device must accept any interference received, including interference that may cause undesirable operation.
To satisfy FCC exterior labeling requirements, the following text must be
placed on the exterior of the end product.
Contains Transmitter Module FCC ID: A3LWCB940M
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.
-The OEM integrator is responsible for ensuring the end-user has no manual instruction to remove or install-module.
-The module is limited to installation in mobile or fixed applications.
IC approval
This device contains license-exempt transmitter(s)/receiver(s) that comply
with Innovation, Science, and Economic Development Canada’s license-exempt
RSS(s). Operation is subject to the following two conditions:
- This device may not cause interference.
- This device must accept any interference, including interference that may cause undesired operation of the device.
The host device must be labeled to display the Industry Canada certification
number of the module.
Contains transmitter module IC:649E-WCB940M
IMPORTANT NOTE
This device complies with FCC & IC radiation exposure limits set forth for an
uncontrolled environment. This device should be installed and must not be co-
located or operating in conjunction with any other antenna or transmitter.
This device is intended only for OEM integrators under the following
conditions:
- This module may not be co-located with any other transmitters or antennas.
- The antenna must be installed such that 20cm is maintained between the antenna and users.
As long as the 2 conditions above are met, further transmitter test will not
be required. However, the OEM integrator is still responsible for testing
their end-product for any additional compliance requirements with this module
installed.
In the event that these conditions cannot be met, then the FCC & IC
authorizations are no longer considered valid and the FCC ID cannot be used on
the final product. In these circumstances, the OEM integrator will be
responsible for re-evaluating the end product including this module and
obtaining separate FCC & IC authorizations.
FCC regulations restrict the operation of this device to indoor use only. The
operation of this device is prohibited on oil platforms, cars, trains, boats,
and aircraft, except that operation of this device, is permitted in large
aircraft while flying above 10,000 feet.
Operation of transmitters in the 5.925-7.125 GHz band is prohibited for
control of or communications with unmanned aircraft systems.
User Information
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 is restricted to indoor use only within the 5.15 ~ 5.25GHz Band. (Canada)
-User should also be advised that high-power radars are allocated as primary users (i.e. priority users) of the bands 5250-5350 MHz and 5650-5850 MHz and that these radars could cause interference and/or damage to LE-LAN devices.
