FCC Statements This device complies with Part 15 of the FCC Rules. 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. This equipment has been tested and found to comply with the limits for 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 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 nearby electrical devices, 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 CalAmp technical support for help Any changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. To comply with FCC regulations for the device, the following rules must be obeyed during and after installation Keep the cellular antenna of the Cell Module at a safe distance from your head and body while the modem is in use. Maintain a distance of at least 20 cm (8 inches) between the transmitter’s antenna and any person while in use. This device is designed for use in applications that observe the 20 cm separation distance. Consult the Cell Module installation guide for information on approved antennas. Non-Collocation for External Antenna External antenna must not be collocated or operating in conjunction with any other antenna or transmitter. Collocation is defined as any antenna or radiating element positioned within 20cm of another antenna or radiating element. The supplied internal antenna for 802.15 will insure 20cm separation from a properly mounted, vertically positioned external cellular antenna. Only FCC approved antennae can be used with the 802.15 transceiver. Consult with CalAmp, Corp. or FCC OET website, www.fcc.gov/oet/, for a list of approved antenna solutions for this device.
Safety Issues The use of cellular telephones or devices in aircraft is illegal. Use in aircraft may endanger operation and disrupt the cellular network. Failure to observe this restriction may result in suspension or denial of cellular services to the offender, legal action or both.  Do not operate in the vicinity of gasoline or diesel-fuel pumps unless use has been approved and authorized  Do not operate in locations where medical equipment that the device could interfere with may be in use  Do not operate in fuel depots, chemical plants, or blasting areas unless use has been approved and authorized  Use care if operating in the vicinity of protected personal medical devices, i.e., hearing aids and pacemakers  Operation in the presence of other electronic equipment may cause interference if equipment is incorrectly protected. Follow recommendations for installation from equipment manufacturers.

1. OVERVIEW 1.1. Advisory Symbols Warning! Improper usage or handling may cause non-compliant device operation. Warning! High voltage presents risk of injury due to electric shock. Direct Current (DC). 1.2. Module Identification The label contains the CalAmp part number, serial number, IC and FCC ID numbers. Additional labeling will be required on the end device.
1.3. General Description The CalAmp WiMetryTM Core Module is an Internet Protocol-based, bidirectional wireless data concentrator platform used for advanced metering and demand response monitoring and control applications. The platform also has other smart grid applications and facilitates real-time acquisition of critical usage and rate data from electric, gas or water meters via public wireless networks and the Internet. The WiMetryTM platform supports the latest in cellular 3G high-speed data communications and is backward compatible to existing EV-DO Rev. 0 and 1x networks. WiMetryTM takes advantage of ongoing investments made by cellular network operators to build-out, improve and maintain ubiquitous, reliable wireless networks using the latest standards, thereby enabling utility companies to focus on their core business rather than having to establish their own proprietary wireless networks. The Core Module is designed to be easily integrated into various end devices. This document describes the process and rules for integrating the core module into an end device. It includes descriptions of all external interfaces and instruction on how to communicate and power the device. This document does not cover the software functionality of the device. Refer to end product documentation for more information on the application software.

Cellular Module The Core Module contains a mini PCI express connector (P3) for connecting a 3G cell module. CalAmp will install the cell module prior to shipment. The Cell module will contain its own unique antenna connector and installation requirements. Refer to cell module manufacturer product documentation for installation rules and antenna options with regards to FCC certification. 2.8. 802.15 Antenna To insure FCC compliance, the Core Module 802.15 modular transmitter utilizes a U.FL antenna coupler and requires a unique coaxial feed assembly direct to the external antenna. Any antenna used with the module must meet certification requirements. To comply with FCC approval for the EVDO device, do not use a 2.4GHZ antenna with a gain greater than 2dBi. To comply with FCC approval for the device, do not place the 802.15 antenna within 20cm of the cellular antenna or any other antennas in the system.
3. GENERAL INSTALLATION GUIDELINES Refer to module overview images, Figures 1 and 2, for locations of mounting holes. The core module is mounted using the four mounting holes on the corners of the module using #4 screws. Although not necessary for emissions compliance, it is recommended that each mounting hole or the associated edge copper rails are electrically connected to the chassis ground of the assembly enclosure. Minimum single-shielded coax is required for emissions compliance of both cellular and 802.15 antenna feeds. Cables should route across top side of board, preferably outside of PWA perimeter. Enclosures and cable feed recommendations are shown below.
