FCC Regulatory Compliance
Important Notice to OEM integrators
1. This module is limited to OEM installation ONLY.
2. This module is limited to installation in mobile or fixed applications, according to Part 2.1091(b).
3. The separate approval is required for all other operating configurations, including portable
configurations with respect to Part 2.1093 and different antenna configurations.
4. For FCC Part 15.31 (h) and (k): The host manufacturer is responsible for additional testing to verify
compliance as a composite system. When testing the host device for compliance with Part 15
Subpart B, the host manufacturer is required to show compliance with Part 15 Subpart B while the
transmitter module(s) are installed and operating. The modules should be transmitting, and the
evaluation should confirm that the module's intentional emissions are compliant (i.e. fundamental
and out of band emissions). The host manufacturer must verify that there are no additional
unintentional emissions other than what is permitted in Part 15 Subpart B or emissions are complaint
with the transmitter(s) rule(s). The Grantee will provide guidance to the host manufacturer for Part 15
B requirements if needed.
Important Note
Notice that any deviation(s) from the defined parameters of the antenna trace, as described by the
instructions, require that the host product manufacturer must notify to Fibocom wires Inc. that they
wish to change the antenna trace design. In this case, a Class II permissive change application is
required to be filed by the USI, or the host manufacturer can take responsibility through the change in
FCC ID (new application) procedure followed by a Class II permissive change application.

End Product Labeling
When the module is installed in the host device, the FCC/IC ID label must be visible through a
window on the final device or it must be visible when an access panel, door or cover is easily
re-moved. If not, a second label must be placed on the outside of the final device that contains the
following text: “Contains FCC ID: ZMOSU806LA”.
The FCC ID can be used only when all FCC compliance requirements are met.
Antenna Installation
(1) The antenna must be installed such that 20 cm is maintained between the antenna and users,
(2) The transmitter module may not be co-located with any other transmitter or antenna.
(3) Only antennas of the same type and with equal or less gains as shown below may be used with
this module. Other types of antennas and/or higher gain antennas may require additional
authorization for operation.
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 ZMOSU806LA 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.
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.
Federal Communication Commission Interference 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 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.
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.

List of applicable FCC rules
This module has been tested and found to comply with part 15C, part 22, part 24, part 27, part 90
requirements for Modular Approval.
The modular transmitter is only FCC authorized for the specific rule parts (i.e., FCC transmitter rules)
listed on the grant, and that the host product manufacturer is responsible for compliance to any other
FCC rules that apply to the host not covered by the modular transmitter grant of certification. If the
grantee markets their product as being Part 15 Subpart B compliant (when it also contains
unintentional-radiator digital circuity), then the grantee shall provide a notice stating that the final host
product still requires Part 15 Subpart B compliance testing with the modular transmitter installed.
This device is intended only for OEM integrators under the following conditions: (For
module device use)
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.
As long as 2 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.
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.
