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 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 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
transmitters This device and its antenna(s) must not be co-located or
operating in conjunction with any other antenna or transmitter
IMPORTANT NOTE:
FCC Radiation Exposure Statement:
This equipment complies with FCC radiation exposure limits set forth for an
uncontrolled environment. This equipment should be installed and operated with
minimum distance 20 cm between the radiator & your body.
This module is intended for OEM integrator. The OEM integrator is responsible
for compliance to all the rules that apply to the product into which this
certified RF module is integrated.
Additional testing and certification may be necessary when multiple modules
are used.
20 cm minimum distance has to be able to be maintained between the antenna and
the users for the host this module is integrated into. Under such
configuration, the
FCC radiation exposure limits set forth for an population/uncontrolled
environment can be satisfied.
Any changes or modifications not expressly approved by the manufacturer could
void the user’s authority to operate this equipment.
This module has been approved to operate with the antenna types listed below,
with the maximum permissible gain indicated.
| Antenna Type | Model Number | Gain(dBi) |
|---|---|---|

The end product shall bear the following 15.19 statement: 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.
This module has been approved under stand-alone configuration.
OEM integrator has be limited the operation channels in channel 1-11 for
2.4GHz band.
The separate approval is required for all other operating configurations,
including portable configurations with respect to Part 2.1093 and different
antenna configurations
The information on how to configure test modes for host product evaluation for
different operational conditions for a stand-alone modular transmitter in a
host, versus with multiple, simultaneously transmitting modules or other
transmitters in a host can be found at KDB Publication 996369 D04
Appropriate measurements (e.g. 15 B compliance) and if applicable additional
equipment authorizations (e.g. SDoC) of the host product to be addressed by
the integrator/manufacturer.
This module is only FCC authorized for the specific rule parts 15.247, 15.407
listed on the grant, and the host product manufacturer is responsible for
compliance to any
other FCC rules that apply to the host product as being Part 15 Subpart B
compliant.
