2 WLR089U0/WLR089UC Usage Instructions under Modular Approval

The WLR089U0 module has received regulatory approval for the following countries:

– United States/FCC ID: 2ADHKR34M

– Canada/ISED:

• IC: 20266-R34M

• HVIN: WLR089U0

• PMN: WLR089U

The WLR089UC module has received regulatory approval for the following countries:

– United States/FCC ID: 2ADHKR34M

– Canada/ISED:

• IC: 20266-R34M

• HVIN: WLR089UC

• PMN: WLR089U

2.1 United States

The WLR089U0/WLR089UC module has received Federal Communications Commission (FCC) CFR47

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

Part15.212 Modular Transmitter approval. Single-modular transmitter approval is defined as a complete RF trans-

mission 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.

The host product itself is required to comply with all other applicable FCC equipment authorizations 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., Suppliers Declaration of Conformity (SDoC) or certification) as appropriate (for example, Bluetooth

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

2.1.1 LABELING AND USER INFORMATION REQUIREMENTS

The WLR089U0/WLR089UC module has been labeled with its own FCC ID number, and 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 also display a label referring to the enclosed module.

This exterior label can use wordings follows:
