Certification Exhibit FCC ID: QZC-REXUAINZ FCC Rule Part: 15.247 ACS Project Number: 15-0286 Manufacturer: Elster Solutions, LLC Model: REXUAI-NZ 5015 B.U. Bowman Drive Buford, GA 30518 USA Voice: 770-831-8048 Fax: 770-831-8598 Model REXUAI-NZ PCBA manual General The Model REXUAI-NZ printed circuit board assembly (PCBA) contains a frequency hopping spread spectrum radio operating in the 916.0-927.6 MHz ISM frequency band. It also contains circuitry for electricity metering. When the REXUAI-NZ module is installed in a plastic housing it forms a complete electricity meter. Installations of multiple REXUAI-NZ meters comprise part of an Advanced Metering Infrastructure (AMI) system that utilizes a proprietary network architecture and protocol devised by Elster Solutions.

It has no user-serviceable parts. USER INFORMATION (PART 15.105) 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:
If you experience trouble with this equipment, please use the Return Material Authorization (RMA) feature available at the Online Customer Services at www.elstersolutions.com. Do not attempt to repair this equipment yourself unless you are replacing the entire module. COMPLIANCE STATEMENT (FCC PART 15.19 AND INDUSTRY CANADA) This device complies with part 15 of the FCC Rules and with Industry Canada license-exempt RSS standard(s). Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and reorient or relocate the receiving antenna increase the separation between the equipment and the 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
(2) this device must accept any interference received, including interference that may cause undesired operation of the device. NONC DE CONFORMIT Cet appareil est conforme la Partie 15 des rgles de la FCC et aux CNR d'Industrie Canada applicables aux appareils radio exempts de licence. L'utilisation de cet appareil est soumise aux deux conditions suivantes : (1) Cet appareil ne doit pas provoquer d'interfrences nocives et (2) cet appareil doit accepter toutes les interfrences reues notamment celles pouvant provoquer un fonctionnement intempestif de l'appareil. ANTENNA COMPLIANCE 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 radiolectrique 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. REXUAI-NZ meter: This radio transmitter has been approved by Industry Canada to operate with the antenna types listed below with the maximum permissible gain and required antenna impedance for each antenna type indicated. Antenna types not included in this list, having a gain greater than the maximum gain indicated for that type, are strictly prohibited for use with this device. REXUAI-NZ meter: Le prsent metteur radio a t approuv par Industrie Canada pour fonctionner avec les types d'antenne numrs ci-dessous et ayant un gain admissible maximal et l'impdance requise pour chaque type d'antenne. Les types d'antenne non inclus dans cette liste, ou dont le gain est suprieur au gain maximal indiqu, sont strictement interdits pour l'exploitation de l'metteur. On Board Printed 900 MHz Slot Antenna: 4.1 dBi WARNING (PART 15.21) Changes or modifications not expressly approved by Elster could void the user's authority to operate the equipment. RF RADIATION SAFETY GUIDELINES This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated to provide a separation distance of at least 26 cm from all persons. COLLOCATION STATEMENT This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.
