Preliminary

2.1 United States

The WFI32E01 modules have received Federal Communications Commission (FCC) CFR47

Telecommunications, Part 15 Subpart C “Intentional Radiators” single-modular approval in accordance

with Part 15.212 Modular Transmitter approval. Single modular transmitter approval is defined as a

complete RF transmission sub-assembly, designed to be incorporated into another device, that must

demonstrate compliance with FCC rules and policies independent of any host. A transmitter with a

modular grant can be installed in different end-use products (referred to as a host, host product, or host

device) by the grantee or other equipment manufacturer, then the host product may not require additional

testing or equipment authorization for the transmitter function provided by that specific module or limited

module device.

The user must comply with all of the instructions provided by the Grantee, which indicate installation

and/or operating conditions necessary for compliance.

A host product itself is required to comply with all other applicable FCC equipment authorization

regulations, requirements, and equipment functions that are not associated with the transmitter module

portion. For example, compliance must be demonstrated: to regulations for other transmitter components

within a host product; to requirements for unintentional radiators (Part 15 Subpart B), such as digital

devices, computer peripherals, radio receivers, etc.; and to additional authorization requirements for the

non-transmitter functions on the transmitter module (i.e., SDoC or Certification) as appropriate (e.g.,

Bluetooth and Wi-Fi transmitter modules may also contain digital logic functions).

2.1.1 Labeling and User Information Requirements

The WFI32E01 module has been labeled with its own FCC ID number. If the FCC ID is not visible when

the module is installed inside another device, then the outside of the finished product into which the

module is installed must display a label referring to the enclosed module. This exterior label can use

wording as follows:

For the WFI32E01PE, WFI32E01UE, WFI32E01PC, WFI32E01UC:

Contains Transmitter Module FCC ID: 2ADHKWFI32E01

Contains FCC ID: 2ADHKWFI32E01

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.

A user's manual for the finished product should include the following statement:

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 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 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
