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.

1.1. 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.

2.7. 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.
