RSS-247 Digital Transmission Systems (DTSs), Frequency Hopping Systems (FHSs) and Licence-Exempt Local Area Network (LE-LAN) Devices FCC Part 15, Class B 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:

Increase the separation between the equipment and receiver. Reorient or relocate the receiving antenna. 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. CAT3 Communications Module ISED RSS-Gen Notice This device complies with Industry Canadas licence-exempt RSSs. Operation is subject to the following two conditions:

(1) This device may not cause interference; and (2) This device must accept any interference, including interference that may cause undesired operation of the device. Le prsent appareil est conforme aux CNR dIndustrie Canada applicables aux appareils radio exempts de licence. Lexploitation est autorise aux deux conditions suivantes :

ISED Canada ICES-003 Compliance CAN ICES-3 (B)/NMB-3(B) Additional testing, Part 15 Subpart B disclaimer The Itron CAT3 modular transmitter is only FCC authorized for the specific rule parts (i.e., FCC transmitter rules) listed on the grant, and that the host product manufacturer is responsible for compliance to any other FCC rules that apply to the host not covered by the modular transmitter grant of certification. If the grantee markets their product as being Part 15 Subpart B compliant (when it also contains unintentional-radiator digital circuity), then the grantee shall provide a notice stating that the final host product still requires Part 15 Subpart B compliance testing with the modular transmitter installed. Changes or modifications to this device not expressly approved by Itron, Inc. could void the users authority to operate the equipment. RF Exposure (FCC/ISED) The users manual for any product that contains this module will contain the following text:

This equipment complies with radiation exposure limits set forth as a mobile classification 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. In order to comply with FCC / ISED RF Exposure requirements, this device must be installed to provide at least 20 cm separation from the human body at all times. Afin de se conformer aux exigences d'exposition RF FCC / ISED, cet appareil doit tre install pour fournir au moins 20 cm de sparation du corps humain en tout temps.

(The CAT3 module has been evaluated within the OW CAT-M1 host for RF exposure compliance) CAT3 Communications Module Miscellaneous The users manual for any product that contains this module will contain the following text:

Professional Installation This module is intended for professional installation by the integrator. The OEM integrator is still responsible for the FCC/ISED compliance requirement of the end product, which integrates this module. Limited Modular Procedures The Itron CAT3 is approved as a module, and Itron as the module manufacturer is responsible for approving the host environment that the limited module is used with. The host for the Itron CAT3 module is the Itron OW CAT-M1 electricity meter. Itron has full control over the manufacture of the module as well as the OW CAT-M1 meter. As a module the fully operational CAT3 has been tested and has shown compliance within the host (OW CAT-M1). Antennas There are no external antenna types approved for use with the Itron CAT3 module installed in the OW CAT-M1. Below are the antennas associated with the CAT3 module. PCB embedded inverted F, -4.21 dBi max gain (900 MHz to 925 MHz) PCB mounted inverted F, 2.58 dBi max gain (746 MHz to 2.155 GHz) For situations where the host manufacturer is responsible for an external connector, the integration instructions shall inform the installer that a unique antenna connector must be used on the Part 15 authorized transmitters used in the host product. Modification and Repairs To ensure FCC compliance and system performance, this device, antenna and/or coaxial assembly shall not be changed or modified without the express written approval of Itron. Any unauthorized modification will void the users authority to operate the equipment. WARNING! This device contains no user serviceable parts. Attempts to repair this device by unauthorized personnel may subject the person to shock hazard if removal of protective covers is attempted. Unauthorized repair will void the warranty and/or maintenance contract with your company. Operational Description The Itron CAT3 is a communications module which utilizes a 900 MHz plus a cellular modem. This module operates within a host unit which is part of a utility network system designed to communicate with other devices in this network such as electricity meters and routers. The module operates on AC voltage which is supplied by the host device. Test Modes Itron uses various test mode programs for test set up which operate separate from production firmware. Host integrators should contact Itron for assistance with test modes needed for module/host compliance test requirements. Recycling Information The product you have purchased contains circuit boards. At the end of the modules useful life, under various state and local laws, it may be illegal to dispose of certain components into the municipal waste system. Check with your local solid waste officials for details about recycling options or proper disposal.

These items are considered as Trade Secrets and therefore public access to the proprietary material could possibly result in duplication of equipment that could severely damage the companys business advantage. I appreciate your assistance in this matter. Sincerely, Chris O'Steen Regulatory Engineer

TUV SUD America, 5945 Cabot Parkway, Suite 100, Alpharetta GA 30005 Date: October 4, 2021 Federal Communications Commission Laboratory 7435 Oakland Mills Road Columbia, MD 21046 Re: FCC ID: SK9CAT3 To Whom It May Concern:

The following application is submitted on behalf of our client, Itrin Inc., for evaluation of their model CAT3 for a new certification under FCC Part 15.247. Device is a WiFi depopulated version of FCC ID: SK9CAT1 and is referencing the frequency hopping data from that filing as it is electrically identical. Spot check data is also included in this filing. I have reviewed the application and supporting documentation and have found them to comply with FCC requirements. I recommend this application for certification. Yours sincerely Jeff Woods TUV SUD Senior Engineer Document: 120780 v1 Page 1 of 1

Federal Communications Commission P.O. Box 429 Columbia, MD 21045 Date: June 15, 2021 RE: Application for Modular Approval Certification for the CAT3 communications module Dear Sir or Madam:

The following information addresses the requirements to support a modular approval as required by FCC Part 15.212, Modular Transmitters. 1. The transmitter section is shielded. Testing has been performed to assure compliance. 2. The CAT3 does not have external modulation or data inputs. The RF section is driven by an on-

board MCU which controls RF data lines and does not allow excessive modulation. 3. The modular transmitter has its own power regulation. 4. The frequency hopping antenna is permanently imbedded into the module circuit board. 5. The CAT3 module was tested in a standalone configuration. 6. The CAT3 register module will be labeled as required. The host equipment will also have the required labeling. 7. Operating requirements are included in the host technical manual. 8. MPE measurements are provided to demonstrate RF compliance. There is a cautionary statement that is included in the technical manual stipulating the 20 cm separation distance.
