Data Sheet

11.3 FCC
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 undesirable operation.
Any changes or modifications not expressly approved by Silicon Labs could void the user’s authority to operate the equipment.
FCC RF Radiation Exposure Statement:
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. End users must follow the specif-
ic operating instructions for satisfying RF exposure compliance. This transmitter meets both portable and mobile requirements in ac-
cordance to the limits exposed in the RF Exposure Analysis. This transmitter must not be co-located or operating in conjunction with
any other antenna or transmitter except in accordance with FCC multi-transmitter product procedures.
OEM Responsibilities to comply with FCC Regulations:
OEM integrator is responsible for testing their end-product for any additional compliance requirements needed with this module instal-
led (for example, digital device emissions, PC peripheral requirements, etc.). Additionally, investigative measurements and spot check-
ing are strongly recommended to verify that the full system compliance is maintained when the module is integrated, in accordance to
the "Host Product Testing Guidance" in FCC's KDB 996369 D04 Module Integration Guide V01.
• In the typical case when the integral antenna of the WGM160P22A is used, a minimum separation distance of 40 mm must be main-
tained at all times between the human body and the radiator (antenna) to meet the SAR exemption for portable conditions. When the
WGM160P22N is used instead, the minimum separation distance is also 40 mm, unless only the RF port 2 is used with a dipole
antenna, in which case the minimum distance is 37 mm.
• The transmitter module must not be co-located or operating in conjunction with any other antenna or transmitter except in accord-
ance with FCC multi-transmitter product procedures.
Important Note:
In the event that these conditions cannot be met, then for the FCC authorization to remain valid the final product will have to undergo
additional testing to evaluate the RF exposure, and a permissive change will have to be applied with the help of the customer's own
Telecommunication Certification Body.
End Product Labeling
The variants of WGM160P Modules are labeled with their own FCC ID. If the FCC ID is 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 be labeled in a visible area with the following:
"Contains Transmitter Module FCC ID: QOQWGM160P"
Or
"Contains FCC ID: QOQWGM160P"
The OEM integrator has to be aware not to provide information to the end user regarding how to install or remove this RF module or
change RF related parameters in the user manual of the end product.
Class B Device Notice
Note: 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 equip-
ment 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 in-
stallation. 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
