1.1 United States
The WBZ451 module has 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., Suppliers Declaration of Conformity (SDoC) or certification) as appropriate (e.g., Bluetooth and Wi-Fi
transmitter modules may also contain digital logic functions).
1.1.1 Labeling and User Information Requirements
The WBZ451 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
display a label referring to the enclosed module. This exterior label must use the following wording:
The user's manual for the finished product must include the following statement:
