- If the end-product using the Module is designed to have an antenna port that is accessible to the end-user then a unique antenna connector (as permissible by FCC) must be used (e.g. RP (Reverse Polarity)-SMA socket).
- If an RF coaxial cable is used between the module RF output and the enclosure, then a unique antenna connector must be used in the enclosure wall for interface with antenna.

The host product manufacturer must ensure that the RF behavior adheres to the
certification (e.g. FCC, ISED) requirements when the module is installed in
the final host product.
The availability of some specific channels and/or operational frequency bands
are country dependent and should be programmed at the Host product factory to
match the intended destination. Regulatory bodies prohibit exposing the
settings to the end user. This requirement needs to be taken care of via Host
implementation.
The Host product manufacturer must ensure that the RF behavior adheres to the
certification (e.g. FCC, ISED) requirements when the module is installed in
the final Host product.
Host Board Top Layer Instructions
The top layer (underneath the module) of the host PCB must be ground with as many GND vias as possible.
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
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).
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:
For the WLR089U0/WLR089UC
Contains Transmitter Module
FCC ID: 2ADHKR34M
Contains FCC ID: 2ADHKR34M
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 product must 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 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 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
Additional information on labeling and user information requirements for Part 15 devices can be found in KDB Publication 784748, which is available at the FCC Office of Engineering and Technology (OET) Laboratory Division Knowledge Database (KDB) https://apps.fcc.gov/oetcf/kdb/index.cfm
RF EXPOSURE
All transmitters regulated by FCC must comply with RF exposure requirements.
KDB 447498 General RF Exposure Guidance provides guidance in determining
whether proposed or existing transmitting facilities, operations or devices
comply with limits for human exposure to Radio Frequency (RF) fields adopted
by the Federal Communications Commission (FCC).
From the FCC Grant: Output power is conducted. This grant is valid only when
the module is sold to OEM integrators and must be installed by the OEM or OEM
integrators. This transmitter is restricted for use with the specific
antenna(s) tested in this application for Certification. The antenna(s) used
with this transmitter must be installed to provide a separation distance of at
least 20 mm from all persons and must not be co-located or operating in
conjunction with any other antenna or transmitter.
APPROVED EXTERNAL ANTENNAS
To maintain modular approval in the United States, only the antenna types that
have been tested shall be used. It is permissible to use different antenna,
provided the same antenna type, antenna gain
(equal to or less than), with similar in-band and out of band characteristics
(refer to specification sheet for cutoff frequencies).
For WLR089U0/WLR089UC, Testing was performed with the antenna types listed in
table mentioned in the Table 1-1.
MODULE INTEGRATION IN THE HOST PRODUCT
Host products are to ensure continued compliance as per KDB 996369 Module
Integration Guide.
