Regulatory Statement (FCC)
•Part 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.
•Part 15.105 Statement (Class B)
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.
•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. This device
must not be co-located or operating in conjunction with any other antenna or
transmitter.

Regulatory Statement (FCC)
Regulatory notice to host manufacturer according to KDB 996369 D03 OEM
Manual v01
List of applicable FCC rules
This module has been granted modular approval as below listed FCC rule parts.
- FCC Rule parts 15C(15.247,15.407)
Summarize the specific operational use conditions
The OEM integrator should use equivalent antennas which is the same type and equal
or less gain then an antenna listed in this instruction manual.
RF exposure considerations
The module has been certified for integration into products only by OEM integrators
under the following condition:
-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.
-The transmitter module must not be co-located or operating in conjunction with any
other antenna or transmitter except in accordance with FCC multi-transmitter product
procedures.
-Mobile use
As long as the three conditions above are met, further transmitter testing will not be
required.
OEM integrators should provide the minimum separation distance to end users in their
end-product manuals.

•Label and compliance information
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
