General
The Model REXUA-NZ printed circuit board assembly (PCBA) contains a frequency hopping spread spectrum
radio operating in the 902.4-927.6 MHz ISM frequency band. It also contains circuitry for electricity metering.
When the REXUA-NZ module is installed in a plastic housing it forms a complete electricity meter. Installations
of multiple REXUA-NZ meters comprise part of an Advanced Metering Infrastructure (AMI) system that utilizes a
proprietary network architecture and protocol devised by Elster Solutions.

FCC and Industry Canada Compliance
The radio module is manufactured directly onto the meter main circuit board, and the module is inserted into
the electronic housing of the meter at manufacture. 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:
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
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 licence-exempt RSS standard(s).
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 of the device.
ÉNONCÉ DE CONFORMITÉ
Cet appareil est conforme à la Partie 15 des règles 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'interférences nocives et (2) cet appareil doit accepter toutes les
interférences reçues 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.
Conformément à la réglementation d'Industrie Canada, le présent émetteur radio peut fonctionner avec une
antenne d'un type et d'un gain maximal (ou inférieur) approuvé pour l'émetteur par Industrie Canada. Dans le
but de réduire les risques de brouillage radioélectrique à l'intention des autres utilisateurs, il faut choisir le
type d'antenne et son gain de sorte que la puissance isotrope rayonnée équivalente (p.i.r.e.) ne dépasse pas
l'intensité nécessaire à l'établissement d'une communication satisfaisante.
REXUA-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.
REXUA-NZ meter: Le présent émetteur radio a été approuvé par Industrie Canada pour fonctionner avec les
types d'antenne énumérés ci-dessous et ayant un gain admissible maximal et l'impédance requise pour
chaque type d'antenne. Les types d'antenne non inclus dans cette liste, ou dont le gain est supérieur au gain
maximal indiqué, sont strictement interdits pour l'exploitation de l'émetteur.
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.
DIRECTIVES DE SÉCURITÉ DE RADIOFRÉQUENCE
Cet équipement est conforme aux limites d'exposition aux radiations définies par la Commission Fédéral des
Communications (FCC) pour un environnement non contrôlé. Cet équipement doit être installé et utilisé à une
distance d'au moins 26 cm de séparation de toutes personnes
COLLOCATION STATEMENT
This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.
DÉCLARATION DE CO-LOCALISATION
Cet émetteur ne doit pas être co-localisé ou opérant en conjonction avec aucune autre antenne ou
transmetteur.
