DOCUMENT PURPOSE This document describes the requirements for installation and use of the 2.4 GHz Communications Option Board functions as required for FCC Certification. 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.

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.

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. 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 engineering practice dictates that the antenna be kept clear of obstacles to ensure maximum performance. Elster Integrated Solutions, LLC 208 South Rogers Lane Raleigh, NC 27610
