Professional Installation Instruction
Federal Communication Commission Interference Statement
This device complies with Part 15 of the FCC 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 undesired operation.
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 transmitter must not be co-located or operating in conjunction with any other antenna or transmitter
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 & your body.This module is intended
for OEM integrators only. Per FCC KDB 996369 D03 OEM Manual v01 guidance, the
following conditions must be strictly followed when using this certified
module:
KDB 996369 D03 OEM Manual v01 rule sections:
-
List of applicable FCC rules
This module has been tested for compliance to FCC Part 15. -
Summarize the specific operational use conditions
The module is tested for standalone mobile RF exposure use condition. Any other usage conditions such as co-location with other transmitter(s) or being used in a portable condition will need a separate reassessment through a class II permissive change application or new certification. -
Limited module procedures
Not applicable. -
Trace antenna designs
Not applicable. -
RF exposure considerations
This equipment complies with FCC mobile 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 & your body.If the module is installed in a portable host, a separate SAR evaluation is required to confirm compliance with relevant FCC portable RF exposure rules. -
Antennas
The following antennas have been certified for use with this module; antennas of the same type with equal or lower gain may also be used with this module. The antenna must be installed such that 20 cm can be maintained between the antenna and users.
-
Label and compliance information
The final end product must be labeled in a visible area with the following: “Contains FCC ID: 2ADWC-EK-ST50H”.
The grantee’s FCC ID can be used only when all FCC compliance requirements are met. -
Information on test modes and additional testing requirements
This transmitter is tested in a standalone mobile RF exposure condition and any co-located or simultaneous transmission with other transmitter(s) or portable use will require a separate class II permissive change re-evaluation or new certification. -
Additional testing, Part 15 Subpart B disclaimer
This transmitter module is tested as a subsystem and its certification does not cover the FCC Part 15 Subpart B (unintentional radiator) rule requirement applicable to the final host. The final host will still need to be reassessed for compliance to this portion of rule requirements if applicable. As long as all 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 required with this module installed.
IMPORTANT NOTE:
In the event that these conditions can not 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 can not 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.
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.
OEM/Host manufacturer responsibilities
OEM/Host manufacturers are ultimately responsible for the compliance of the
Host and Module. The final product must be reassessed against all the
essential requirements of the FCC rule such as FCC Part 15 Subpart B before it
can be placed on the US market. This includes reassessing the transmitter
module for compliance with the Radio and EMF essential requirements of the FCC
rules. This module must not be incorporated into any other device or system
without retesting for compliance as multi-radio and combined equipment.
