Information for Host Integrators
This module is intended to be integrated into enclosures which can be mounted onto
head-worn equipment such as hard hats. The guidelines described within this
document are provided to the host integrators which manufacture and market these
enclosures and / or the final head-worn equipment. In order to meet the conditions of
compliance with FCC and ISED rules, including RF exposure, the following guidelines
should be adhered to. If these guidelines are followed, the host integrator may
incorporate this device into their head-worn equipment and market it with no further
restrictions. If the guidelines are not adhered to, it may be necessary for the host
integrator to perform additional testing and/or obtain additional approvals.
Antennas
The module is designed and tested to be used with the built-in antennas only. The
built-in antennas cannot be replaced or augmented in any way without requiring
additional authorization for operation.
Rear Enclosure Placement within the Host Enclosure
In order to ensure RF exposure compliance, the rear enclosure of the module should
be oriented as shown below. The inner curved surface of the module should be
oriented to face the back of the user’s head as shown in the diagram. This will ensure
that the rear enclosure remains at least 0mm from the end user as they were in RF
exposure regulatory testing. If the rear enclosure is oriented in some other way, RF
exposure compliance cannot be ensured without additional testing and the host
product would require additional regulatory approvals. Addition of metallic
components in or near the rear enclosure may also require additional RF exposure
testing.

Simultaneous Transmission with Transmitters Added by Host
Integrator
If the host integrator adds any additional transmitters to their integration enclosure
other than those included in the module, they are responsible to re-evaluate RF
exposure compliance for simultaneous transmission scenarios. This can be done
according to FCC KDB 447498 or other applicable regulatory standards. It may require
further RF exposure testing and/or regulatory submittals which would be the
responsibility of the host integrator.
Orientation of Rear Enclosure Relative to the User’s Head

Information to be Supplied to the End User by the Host
Integrator
The host integration enclosure must be labeled with “Contains FCC ID:C3K1925” and
“Contains IC: 3048A-1855” if the module labels are not visible to the end user at the
time of purchase of the end product.
The module must be installed into the integration enclosure and operated in
accordance with the instructions and documentation provided by Microsoft. Microsoft
is not responsible for any radio interference caused by modification of the module
outside the scope of these instructions and documentation. Microsoft may be
contacted for information on specific test modes for evaluation of host product in
different operational conditions (stand-alone modular transmitter in a host or
multiple, simultaneously transmitting modules or other transmitters in a host).
Additional guidance for testing host products is given in KDB 996369 D04 Module
Integration Guide.
This modular transmitter is authorized for FCC / ISED Canada for the specific rule parts
detailed in this document (RSS 247 for Canada, Part 15C (15.247) and 15E for USA).
The host product manufacturer is responsible for compliance to any other rules that
apply to the host not covered by the modular transmitter grant of certification such as
Part 15 Subpart B and ICES-003 for digital circuity.

Disposal of Waste Batteries and Electrical & Electronic Equipment
This symbol on the product or its batteries or its packaging means that this
product and any batteries it contains must not be disposed of with your
household waste. Instead, it is your responsibility to hand this over to an
applicable collection point for the recycling of batteries and electrical and
electronic equipment. This separate collection and recycling will help to conserve
natural resources and prevent potential negative consequences for human health and
the environment due to the possible presence of hazardous substances in batteries
and electrical and electronic equipment, which could be caused by inappropriate
disposal. For more information about where to drop off your batteries and electrical
and electronic waste, please contact your local city/municipality office, your
household waste disposal service, or the shop where you purchased this product.

This Class B digital apparatus complies with Part 15 of the U.S. Federal
Communications Commission (FCC) rules, Innovation, Science and Economic
Development (ISED) Canada licence-exempt RSS standards. Operation is subject to
the following two conditions: (1) this device may not cause interference, and (2) this
device must accept any interference received, including interference that may cause
undesired operation.
Any changes or modifications to this device not expressly approved by Microsoft
could void the user’s authority to operate the device.
Radio and TV Interference Regulations

Microsoft hardware device(s) can radiate radio frequency (RF) energy. If not installed
and used in strict accordance with the instructions given in the printed documentation
and/or onscreen help files, the device may cause harmful interference with other
radio-communications devices (for example AM/FM radios, televisions, baby monitors,
cordless phones, etc.). There is, however, no guarantee that RF interference will not
occur in a particular installation. To determine if your hardware device is causing
interference to other radio-communications devices, turn off and unplug the device
from any external power source. If the interference stops, it was probably caused by
the device. If this hardware device does cause interference, try the following measures
to correct it:
•Relocate the antenna of the other radio-communications device (for example
AM/FM Radios, televisions, baby monitors, cordless phones, etc.) until the
interference stops.
•Move the hardware device farther away from the radio or TV, or move it to one
side or the other of the radio or TV.
•Plug the device into a different power outlet so that the hardware device and
radio or TV are on different circuits controlled by different circuit breakers or
fuses.
•If necessary, ask your device dealer or an experienced radio-TV technician for
more suggestions.
For more information about interference issues, go to the FCC Web site at:
http://www.fcc.gov/cgb/consumerfacts/ interference.html. You can also call the FCC at
1-888-CALL FCC to request Interference and Telephone Interference fact sheets.
