2.4 GHz Communications Option Board
Installation Guide

1. OVERVIEW

1.1. DOCUMENT PURPOSE

This document describes the requirements for installation and use of the 2.4 GHz
Communications Option Board functions as required for FCC Certi f ication.

1.2. FCC INFORMATION TO THE USER

1.2.1. Product Information

Model ZOB FCC ID G8J ZGB1 IC: 4557C ZGB1

This device complies with Part 15 of the FCC rules and with
Industry Canada RSS-GEN. Operation of this device is subject
to the following 2 conditions: (1) This device may not cause harmful
interference, and (2) this device must accept any interference
received including any interference that may cause undesired operation.

1.2.2. General Information

Changes or modifications to the equipment not expressly approved by Elster could void the
user's authority to operate this equipment.

NOTE: 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.
—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.

A separation distance of at least 8 inches (20 cm) is to be maintained between the antenna
and the human body and must not be co-located or operated in conjunction with any other
transmitter or antenna.

The Term “IC” before the certification/registration number only signifies that the Industry
Canada technical specifications were met.

1.2.3. Labeling

If the FCC ID is not visible when the module is installed inside another device, then the
outside of the device into which the module is installed must also display a label referring to
the enclosed module. This exterior label can use wording such as the following: “Contains
Transmitter Module FCC ID: G8J ZGB1” or “Contains FCC ID: G8J ZGB1.” Any similar
wording that expresses the same meaning may be used. The Grantee may either provide
such a label, an example of which must be included in the application for equipment
authorization, or, must provide adequate instructions along with the module which explain this
requirement. In the latter case, a copy of these instructions must be included in the
application for equipment authorization.

1.2.4. RF Exposure

A separation distance of at least 20cm from the end user is required.

1.2.5. Co-Located Transmitters

Provisions have been provided on the Interface Connector such that this device will be
disabled if another co-located transmitter is required to transmit.

This device “may not” be operated as a co-located transmitter with other transmitting devices
unless certification is obtained as a new end product.

1.2.6. Additional Testing

Users incorporating this device into their product must test the complete system, with radio
module installed, against the appropriate standard for the host device.

While the applicant for a device into which an authorized module is installed is not required to
obtain a new authorization for the module, this does not preclude the possibility that some
other form of authorization or testing may be required for the device.

Installation Guide

2. INSTALLATION

This device is intended to be used as part of an automated utilities meter reading network
and uses proprietary communications and data to communicate with another host device.

2.1. INTERNAL USE

This device was designed to fit into The Elster Electricity LLC REX2 series of utilities electric
meters. Provisions in the case mechanics have been provided to accept the device as an
insert-able option card. The interface connector is designed to mate directly with the main
board in the electric meter. This device is installed when the electric meter is manufactured at
the factory.

All additional required FCC testing and control for proper operation to meet FCC
requirements as a final product have been met.

2.2. EXTERNAL USE

This device is not for sale to the general public.
Sale of this device outside of the company will be strictly controlled to ensure its compliance.

2.3. CLEARANCE

The device should be installed in a manner such that a clearance distance of 8mm will be
maintained from the front and back of the device to prevent adversely affecting the antenna
incorporated onto the Circuit Board.

Antenna testing in the intended host device did not show any significant deterioration in
performance caused by close proximity of wiring or case mechanics. Good engineeri ng
practice dictates that the antenna be kept clear of obstacles to ensure maximum
performance.
