Model RX2EA4F PCBA manual
General
The Model RX2EA4F 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 RX2EA4F module is installed in a housing and meter base, it forms a complete electricity meter.
Installations of multiple REX2 meters comprise part of an Advanced Metering Infrastructure (AMI) system that
utilizes a proprietary network architecture and protocol devised by Elster Solutions.

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.
REX2 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.
REX2 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 Inverted F Antenna: 3.5 dBi
• PCTEL (MAXRAD) MFB9150 unity gain Fiberglass omnidirectional: 2.15 dBi
• PCTEL (MAXRAD) MFB9153 3dB Fiberglass omnidirectional: 5.15 dBi
• Antenex TRA9023P(NP) (white body) or Antenex TRAB9023P(NP) (black body): 3 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 20cm from all
persons.
COLLOCATION STATEMENT
This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.
