FCC Statement
This device complies with part 15 of the FCC rules. Operation is subject to the following two conditions: (1) thi
s device may not cause harmful interference, and (2) this device must accept any interference received, incl
uding interference that may cause undesired operation.
Changes or modifications not expressly approved by the party responsible for compliance could void the user’
s authority to operate the equipment.
NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursua
nt to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful inte
rference in a residential installation. This equipment generates uses and can radiate radio frequency energy a
nd, if not installed and used in accordance with the instructions, may cause harmful interference to radio com
munications. 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 turn
ing 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 important announcement
Important Note:
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 20cm between the radiator and your
body.
This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.
Country Code selection feature to be disabled for products marketed to the US/Canada.
This device is intended only for OEM integrators under the following conditions:
1. The antenna must be installed such that 20 cm is maintained between the antenna and users, and
2. The transmitter module may not be co-located with any other transmitter or antenna,
3. For all products market in US, OEM has to limit the operation channels in CH1 to CH11 for 2.4G band
by supplied firmware programming tool. OEM shall not supply any tool or info to the end-user
regarding to Regulatory Domain change. (if modular only test Channel 1-11)
As long as the three conditions above are met, further transmitter testing will not be required. However, the
OEM integrator is still responsible for testing their end-product for any additional compliance requirements
required with this module installed.
Important Note:
In the event that these conditions cannot be met (for example certain laptop configurations or co-location
with another transmitter), then the FCC authorization is 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 the transmitter) and obtaining a separate FCC authorization.
End Product Labeling
The final end product must be labeled in a visible area with the following" Contains FCC ID: 2AL6KBLM7603NU4 ".
Manual Information to the End User
The OEM integrator has to be aware not to provide information to the end user regarding how to install or
remove this RF module in the user’s manual of the end product which integrates this module.
The end user manual shall include all required regulatory information/warning as show in this manual.
Integration instructions for host product manufacturers according to KDB 996369 D03 OEM
Manual v01
2.2 List of applicable FCC rules
CFR 47 FCC PART 15 SUBPART C has been investigated. It is applicable to the modular transmitter
2.3 Specific operational use conditions
This module is stand-alone modular. If the end product will involve the Multiple simultaneously transmitting condition or different
operational conditions for a stand-alone modular transmitter in a host, host manufacturer have to consult with module manufacturer
for the installation method in end system.
2.4 Limited module procedures
This module is Limited single modular without shielding, host manufacturer have to consult with module manufacturer for the
module limiting conditions when integrate the module in the host. module manufacturer should reviews detailed test data or host
designs prior to giving the host manufacturer approval.
2.5 Trace antenna designs
Not applicable
2.6 RF exposure considerations
This equipment complies with FCC 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.
2.7 Antennas
antenna types listed below, with the maximum permissible gain indicated. Antenna types not included in this list that have a
gain greater than the maximum gain indicated for any type listed are strictly prohibited for use with this device.

2.8 Label and compliance information
The final end product must be labeled in a visible area with the following" Contains FCC ID:2AL6KBL-M7603NU4".
2.9 Information on test modes and additional testing requirements
Host manufacturer which install this modular with limit modular approval should perform the test of
radiated emission and spurious emission according to FCC part 15C:15.247 and 15.209 requirement, only
if the test result comply with FCC part 15.247 and 15.209 requirement, then the host can be sold legally.
