LMU-3000 & OBD-II Extender Cable Installation Guide

Regulatory Information

Human Exposure Compliance Statement

Pursuant to 47 CFR § 24.52 of the FCC Rules and Regulations, personal communications services (PCS) equipment is subject to the radio frequency radiation exposure requirements specified in § 1.1307(b), § 2.1091 and § 2.1093, as appropriate.

CalAmp certifies that it has determined that the LMU-30xx/CVF-3030 complies with the RF hazard requirements applicable to broadband PCS equipment operating under the authority of 47 CFR Part 24, Subpart E of the FCC Rules and Regulations. This determination is dependent upon installation, operation and use of the equipment in accordance with all instructions provided.

The LMU-30xx/CVF-3030 is designed for and intended to be used in fixed and mobile applications.

“Fixed” means that the device is physically secured at one location and is not able to be easily moved to another location. “Mobile” means that the device is designed to be used in other than fixed locations and generally in such a way that a separation distance of at least 20 cm is normally maintained between the transmitter’s antenna and the body of the user or nearby persons. The LMU-26xx is not designed for or intended to be used in portable applications (within 20 cm of the body of the user) and such uses are strictly prohibited.

To ensure that the LMU-30xx/CVF-3030 complies with current FCC regulations limiting both maximum RF output power and human exposure to radio frequency radiation, a separation distance of at least 20 cm must be maintained between the unit’s antenna and the body of the user and any nearby persons at all times and in all applications and uses. Additionally, in mobile applications, maximum antenna gain must not exceed 3 dBi.

Hardware Precautions

Electrical Over-Stress (EOS): The LMU-30xx/CVF-3030 GPS receiver can be damaged if exposed to an RF level that exceeds its maximum input rating. Such exposure can happen if a nearby source transmits an RF signal at sufficiently high level to cause damage.

Storage and Shipping: One potential source of EOS is proximity of one LMU-30xx/CVF-3030 GPS Antenna to another LMU-30xx/CVF-3030 GSM Antenna. Should one of the units be in a transmit mode, the potential exists for the other unit to become damaged. Therefore, any LMU-30xx/CVF-3030 should be kept at least four inches apart from any active LMU-30xx/CVF-3030 or any other active high power RF transmitter with power greater than 1 Watt.

LMU3000 and OBD-II Extender Cable Overview

The LMU-30xx/CVF-3030 features a small size, superior GPS design, OBD-II interface, and a 3-axis accelerometer. These features enable the LMU-30xx/CVF-3030 to access vehicle diagnostic interface data, track vehicle speed and location, and operational information.

Typically, the LMU-30xx/CVF-3030 connects directly into the vehicle’s OBD-II port and requires no additional connections. For protected installations, the LMU-30xx/CVF-3030 is installed under the dash, and then is connected to an OBD-II Extender Cable (P/N 144301) that plugs directly into the vehicle’s OBD-II port. This installation couples a zip-tie secured around the device with a tamper seal applied to protect against accidental interference and to deter intentional tampering. When the tamper seal is removed, the seal self-destructs to indicate removal and leaves behind a dot-pattern residue on the device.

Suggested Tools and Materials

The following materials are required for proper installation of the LMU-30xx/CVF-3030 and OBD-II Extender Cable. No additional tools are required.

Installation

For a protected installation, the LMU-30xx/CVF-3030 device is typically installed under the vehicle dashboard on the driver side, however, another common installation location include behind the A-pillar panel on the driver side of the vehicle. This section outlines the steps in sequential order for installing the components in a typical installation

• Disassemble Vehicle Panels
• Installation of LMU-30xx/CVF-3030 Device and OBD-II Extender Cable
• Successful Installation Verification
• Reassemble Vehicle Panels

Note: Please perform the installation with the vehicle ignition on to provide the device with power during the installation process.

Disassemble Vehicle Panel

The first step of the installation requires removing the panels on the driver’s side of the vehicle. The panel you remove depends on the selected install location. The following instructions show the typical under the dashboard panel removal.

To Remove the Panels:

1. Remove the panel above the vehicle's OBD-II Port.

2. Place your hand on the panel indentation, and then gently pull down until the panel snaps out.

3. Remove the panel behind and next to the steering column.

Place your hand on the panel, and then gently pull the panel outward until the left-side of the panel snaps out.

Connect LMU3000 Device & OBD-II Extender Cable

After you have successfully removed the panels, connect the OBD-II Extender Cable and LMU-30xx.

1. Hold the OBD-II Extender Cable by the female connector.

2. Guide the OBD-II Extender Cable from below the dashboard up through the panel opening

3. Connect the LMU-30xx device to the female connector of the OBD-II Extender Cable.  To deter potential device tampering, apply a piece of tamper tape over the connection. When the tamper tape is removed, the tape self-destructs to indicate removal and leaves behind a residue on the device.

4. Place a female-side (loop-side) piece of Velcro on the non-label side of LMU-30xx device. 

5. Plug the male connector of the OBD-II Extender Cable directly into the vehicle’s OBD-II port.

Optional Security Measures

To deter potential device tampering, apply a piece of tamper tape over the connection. In addition, secure the device beneath the dash.

When the tamper tape is removed, the tape self-destructs to indicate removal and leaves behind a residue on the device.
