CE
The GL-EFR32H modules are in conformity with the essential requirements and other relevant
requirements of the Radio Equipment Directive (RED). Please note that every application using the
GL-EFR32H will need to perform the radio EMC tests on the end product according to EN 301 489-17.
Separate RF testing is not required provided that the customer follows the module manufacturer's
recommendations and instructions and does not make modifications, e.g. to the provided antenna
solutions or requirements.

GL-EFR32H module is inconformity with the essential requirements and other relevant requirements of
the Radio Equipment Directive (RED) at nominal 10 dBm transmit power.

The transmit power of the module is not limited and when an end product is using GL-EFR32H, the end
product manufacturer is responsible that the end product is in inconformity of all relevant requirements of
the RED.

FCC 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.
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,
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
9 / 10

interference by one or more of the following measures:
● Reorient of relocate the receiving antenna.
● Increase the separation between the equipment and receiver.
● Connect the equipment into an outlet on a circuit difference from that to which the receiver is connected.
● Consult the dealer or an experienced radio/TV technician for help.

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 20 cm 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.
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 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:
2AFIW-SH32BZ”
If the FCC identification number 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. This exterior label can use wording such as the following; Contains Transmitter Module FCC ID:
2AFIW-SH32BZ.

Manual Information to the End User:
The OEM integrator has to be aware not 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.
When the module is installed inside another device, the user manual of this device must contain below
warning statements;
1. 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,

10 / 10

2) this device must accept any interference received, including interference that
may cause undesired operation.
2. Changes or modifications not expressly approved by the party responsible for compliance could
void the user’s authority to operate the equipment. The devices must be installed and used in
strict accordance with the manufacturer’s instructions as described in the user documentation that
comes with the product.
