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. 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. Consult Landis+Gyr or an experienced radio technician for help 6 Industry Canada (IC) Compliance Notice This device complies with Industry Canada license-exempt RSS standard(s). 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 d'Industrie Canada applicables aux appareils radio exempts de licence. L'exploitation est autorise aux deux conditions suivantes : (1) l'appareil e doit pas produire de brouillage, et (2) l'utilisateur de l'appareil doit accepter tout brouillage radiolectrique subi, mme si le brouillage est susceptible d'en compromettre le fonctionnement.. Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and maximum (or lesser) gain approved for the transmitter by Industry Canada. To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that necessary for successful communication. Conformment la rglementation d'Industrie Canada, le prsent metteur radio peut fonctionner avec une antenne d'un type et d'un gain maximal (ou infrieur) approuv pour l'metteur par Industrie Canada. Dans le but de rduire les risques de brouillage adiolectrique l'intention des autres utilisateurs, il faut choisir le type d'antenne et son gain de sorte que la puissance isotrope rayonne quivalente (p.i.r.e.) ne dpasse pas l'intensit ncessaire l'tablissement d'une communication satisfaisante. RF Exposure Information This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with a minimum distance of 20 cm between the radiator and your body. This transmitter must not be co-located or operated in conjunction with any other antenna or transmitter. Cet quipement est conforme aux limites FCC d'exposition aux radiations dfinies pour un 7 environnement non contrl. Cet quipement doit tre install et utilis une distance minimale de 20cm entre le radiateur et votre corps. Cet metteur ne doit pas tre co-

implants ou exploits en conjonction avec une autre antenne ou metteur.

File James L. Stortz M125, FCC ID: R7PER6R2S2 Modular Approval Request August 17, 2021 To:

From:

Subject:

Scope 47CFR 15.212 communicates requirements for products requesting modular approval. Eight requirements are enumerated along with a request that each of the eight be explained for any product requesting such approval. It is the purpose of this document to respond to those eight requirements regarding the Landis+Gyr product: M125. Modular Approval Requirements 1.1 RF Shielding The M125 module is self-shielding and is not dependent on any component or characteristic of the device into which it is embedded. Shielding is accomplished through a combination of metallic self-shielding components, copper planes, guards, and vias in the PCB. The result is a design that has been proven to be neither sensitive to outside influence nor capable of introducing interference into outside components. 1.2 Buffered Modulation / Data Inputs The M125 module does not have external modulation or data inputs. Rather, the RF sections are driven by an on-board microprocessor which directly controls the RF data lines and operates so as to not allow excessive modulation. 1.3 Power Supply Regulation The M125 module uses a buck/boost DC/DC converter to provide all the electronics with a supply that is fixed, even when the input voltage is varied. 1.4 Antenna Requirement The M125 module utilizes a 0dBi Inverted-F antenna. 1.5 Stand-Alone Testing All testing on the M125 module was conducted standalone. No shields or enclosures were used, other than those fully integrated into the modules themselves. No ferrites were used on data or power lines during testing. These devices are DC powered and exceed applicable conducted emission requirements. 1.6 Labeling As indicated, each M125 module will have its own FCC ID label. In addition, devices into which they are placed will have labels indicating that this module is contained within. Exact text will be as specified in 47CFR 15.212. 1.7 Specific Rules and Operating Requirements The M125 module complies with all pertinent rules for its section. 1.8 RF Exposure Requirements The M125 module complies with all exposure requirements. As a component used in the Utility industry, this product is not intended for use near human operators. This module undergoes continuous, rigorous testing to ensure that full compliance is always maintained. Sincerely, James L.
