1 REGULATORY INFORMATION
1.1 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-26xx 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-26xx 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-26xx 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.
1.2 HARDWARE PRECAUTIONS
Electrical Over-Stress (EOS)
The LMU-26xx 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-26xx GPS Antenna to another LMU-26xx 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-26xx should be kept at least four inches apart from any active
LMU-26xx or any other active high power RF transmitter with power greater than 1 Watt.

3.1 AVAILABLE WIRING HARNESS
The LMU-26XX ships with the 5C908 wiring harness. This harness requires hard wiring of the power,
ground and ignition wire.
The 5C260 is an optional cable with multiple connectors for standard I/O devices, such as buzzer, light
and driver ID sensor. This enables hard wiring of the power, ground and ignition wire except when using
a vPOD or jPOD. Both vPOD and jPOD provide power to the device without the need for hard wiring.
See installation instructions for proper wiring.
The 5C261 is an optional cable with same connectors as the 5C260; however, it is a short harness and
provides power, ground and ignition from the vehicle’s Jbus or OBD port. This must be used with either
the vPOD or jPOD to work properly.

3.3 ENVIRONMENTAL SPECIFICATIONS
The LMU-26xx is designed to operate in environments typically encountered by fleet vehicles, including
wide temperature extremes, voltage transients and potential interference from other vehicle
equipment.
To ensure proper operation in such an environment, the LMU-26xx was subjected to standard tests
defined by the Society of Automotive Engineers (SAE). The specific tests included temperature, shock,
vibration and EMI/EMC. These tests were performed by independent labs and documented in a detailed
test report. In accordance with Appendix A of SAE J1113 Part 1, the Unit is considered a “Functional
Status Class B, Performance Region II” system that requires Threat Level 3 Testing.
The following shows the environmental conditions the LMU-26xx is designed to operate in and the
relevant SAE tests that were performed. No formal altitude tests were conducted.

CalAmp | LMU-26xx Install Guide
4 PRE-INSTALLATION CONSIDERATIONS
The installation of the LMU-26xx and its antennas can have a major impact on device performance. It is
recommended that installers be familiar with the installation of GPS and cellular devices and are
comfortable in a vehicle environment.
4.1 PLAN THE INSTALLATION
Verify Power, Ground and Ignition. Be sure to check each source (power, ground and ignition) to ensure
that the proper signaling exists. This is typically accomplished with a multi-meter.
Before drilling any holes or running any wires, decide where each hardware component will be installed
(LMU-26xx, antennas, peripherals, etc.). Verify that all cables running to the LMU-26xx will not be bent
or constricted. Verify that the LMU-26xx install location is free from direct exposure to the elements
(e.g., sun, heat, rain, moisture etc.).
Be advised that an installation that violates the environmental specifications of the LMU-26xx will void
the warranty.
The best way to ensure a trouble-free installation is to consider your options and make appropriate
decisions before you start. Review the vehicle and determine the best install approach for the LMU-26xx
for the following purposes:
Accurate data gathering and simulation of how customers actually use your solution.
Ongoing monitoring and maintenance of LMU-26xx equipment
Accidental or intentional alteration of the equipment or cable connections.
4.2 SIZE AND PLACEMENT OF LMU-26XX
When planning device installation in a vehicle, take in account the dimensions of the LMU-26xx before
actual installation. Typical installations place the LMU-26xx under the vehicle dashboard, or in the A
Pillar. Verify that you can access to the device, as under some circumstances it may be necessary to add
additional wiring or connections to the LMU-26xx.
Refer to Section 3.3: Environmental Specifications for the exact measurements and specifications of the
LMU-26xx.
Verify the LMU-26xx will fit before drilling any holes or running cable.
Ensure that all cables running to the LMU-26xx will not be bent or constricted. Damage to the cables
may impede the LMU-26xx’s performance.
Verify that the installation point will not violate any of the LMU-26xx’s environmental specification.
Improper installation of the LMU-26xx may void the warranty.
MBUD-0199v3.3 Page 7
Page 14
CalAmp | LMU-26xx Install Guide
4.3 PROTECTION FROM HEAT
We recommend that you do not place the LMU-26xx in an unusually warm location such as directly near
heater vents, hot engine components or in direct sunlight.
Refer to Section3.3: Environmental Specifications for the maximum temperature tolerated by the
LMU-26xx.
4.4 VISIBILITY OF DIAGNOSTIC LEDS
Status LED lights on the front of the LMU-26xx provide valuable information about the operation of the
device. When feasible, attempt to install the LMU-26xx in such a way that the lights are visible with
reasonable ease.
You may find it useful to be able to view the LEDs periodically to make sure that the LMU-26xx is
operating properly. If you encounter a problem or poor performance with the LMU-26xx, you may need
to read the LEDs to troubleshoot the issue. If you cannot resolve the issue, you will need to provide the
LED information to the CalAmp Customer Support Team.
Refer to Section 5.7.2: Status LEDs for information on how to interpret the lights.
4.5 CABLE LENGTH
The harness cables, which are provided for connecting to the LMU-26xx to the vehicle or other auxiliary
device, should be used at the length provided. Do not cut cables. Instead, coil any excess cable length,
making sure not to crimp or flatten the cables.
Figure 5: Coil Excess Cable
Page 8 MBUD-0199v3.3
Page 15
CalAmp | LMU-26xx Install Guide
Figure 6: Tamper Resistant Materials
4.6 MOISTURE AND WEATHER PROTECTION
The LMU-26xx is not a weatherproof device and must be kept dry. The mounting location should be
inside the passenger compartment of the vehicle safe from physical damage and where it is not exposed
to moisture or water. In a typical inside-vehicle installation, this is not a common concern; however,
avoid installing the device below the vehicle’s cup holders, or where rain might easily splash into the
compartment when a door is opened.
If the LMU-26xx is installed in a vehicle with a cab exposed to the weather, additional protection is
required to avoid damage to the device, which could void the warranty. There are numerous
alternatives for protecting the device. One of the best options is to use an Otterbox 2000. You can
purchase from Amazon.com or directly from Otterbox:
http://www.otterbox.com/OtterBox-2000-Clear/OTR3-2000S-01,default,pd.html?dwvar_OTR3-2000S01_color=01&start=3&cgid=otterbox-2000-cases.
Note: For environmentally challenging conditions, consider utilizing the CalAmp TTU-2820.
4.7 PREVENTING ACCIDENTAL OR UNAUTHORIZED MODIFICATION
If you anticipate that fleet drivers or others might tamper with the devices once installed, take steps to
ensure that it is not easy to disconnect the wiring or remove the device from its power source. A tamper
resistant installation couples a zip-tie secured around the device with a tamper seal applied to protect
against potential 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.
MBUD-0199v3.3 Page 9

CalAmp | LMU-26xx Install Guide
5 LMU-26XX INSTALLATION
Installing the LMU-26xx is not difficult, but you must consider the variables involved, such as the vehicle
type and location of existing equipment. Installation time can vary depending upon the installer’s
experience and the vehicle design. The average time for installation is approximately 45 minutes. A
single individual can perform most installation operations. CalAmp offers an installation training
program or can supply a list of recommended installation vendors in your area.
Prior to beginning the installation, verify that you have the parts and tools necessary to complete the
installation. Additionally, read entire installation procedure before beginning. Some of the procedures
require a choice between several installation options.
To install the LMU-26xx:
1. Select location for mounting the device and install it.
For ease of installation, the LMU-26xx has internal GPS and Cellular antennas. Assess cable routes
while considering placement.
2. Install the power, ignition, and ground connections.
3. Install optional buzzer and/or LED button.
4. Install optional I/O connections.
5. Install optional serial cables.
6. Secure all cables to rigid mounts with cable restraints.
7. Verify operation of the LMU-26xx.

CalAmp | LMU-26xx Install Guide
5.1 SELECT THE LOCATION FOR THE LMU-26XX AND INSTALL IT
Determine the desired mounting location. The most common locations are under the dash or on the
front windshield. We recommend under the dash.
For an exposed location, refer to Section 5.1.2: Installation in an Exposed Area.
When determining mounting location, the primary consideration is GPS satellite visibility by the device.
The required installation orientation of the LMU-26xx is label side up. The label should face the sky or
toward windshield.
Note: When performing installation tasks requiring the operation of power, follow recommended safety
procedures, including use of safety eye-wear. In addition, avoid drilling through wires, mounted fixtures
or equipment.

CalAmp | LMU-26xx Install Guide
5.1.1 UNDER DASH INSTALLATION
If the LMU-260 is mounted under the dashboard of the vehicle (Figure 6), ensure the device is mounted
with the “label side” facing up. Do not install the device where it will be obstructed by metal
components. Common install locations are in the void above the glove box (if no airbag present) or
above the vents.
You may need to remove part of the dash facing for access. Typically, the dash facing is attached with
just clips. Do not use excessive force wedging the device into a location under the dash. Use the
provided ‘re-closable fastener tape’ to attach the device to the underside of the dash as described in the
steps below.
Page 12 MBUD-0199v3.3

5.1.2 INSTALLATION IN EXPOSED AREA
If the LMU-26xx is installed in a vehicle with an open cab exposed to the weather, a NEMA rated
enclosure suitable for the application must be used to seal out moisture. A recommended alternative is
a TTU-2820 sealed device available from CalAmp.
5.2 INSTALL POWER CONNECTIONS
The LMU-26xx requires a continuous 12 Volts and an ignition switched 12 Volt signal to operate
correctly.
For Harness 5C908 and 5C260, the LMU-26xx power leads with in line fuses are supplied as part of the
wiring harness.
For harness 5C261, the power and ground are an integral part of the harness, but must be installed with
the vPOD or jPOD.

5.6.5 PRIVACY SWITCH
A privacy switch can be used to prevent the unit from reporting any location information. To do this,
select a DPST switch for mounting on the vehicle dash, preferably with an illumination lamp indicating it
is on. The more typical switch will light up in the “on” condition and indicate a closed circuit, so unless
you select a Normally Closed (NC) switch, the switch will be lit when in the reporting condition. Turning
the switch and light off will cause it to stop reporting.
One pole should be wired between the ignition wire of the vehicle/vpod and the white wire input of the
device harness. This will normally be wired such that the privacy switch disconnects these two wires
when in the “OFF” position, thus preventing the device from receiving an ignition on event from the
vehicle. An “ON” condition, when the switch is lit, will indicate the device is getting the ignition on
message and is reporting normally.
Additionally, we recommend the use of one digital input to send a message that will appear in
FleetOutlook when privacy mode is on. To do this, splice a wire into the red power wire and connect it
to the second pole of the privacy switch. The other end of that switch pole should be wired to an input
on the device. The switch will open the circuit when the privacy switch is in the “OFF” position. Set an
alert to appear in the breadcrumb detail by creating a Device Condition Change alert in FO. Note that
you need to define the input on the device so that Privacy mode will be active when power is removed
from the input.

5.7.3 COMM VERIFICATION
Installers should first verify that the device has acquired a cellular signal and has registered to the
wireless network before completing installation. If this LED is solid, then the device has registered to the
network and established a data session. Acquiring the wireless network and establishing communication
can take several minutes.
5.7.4 GPS VERIFICATION
Next, verify that the GPS receiver is seeing enough satellites to obtain a valid GPS position. If the green
LED is solid, then the device has found GPS service.
5.7.5 INBOUND VERIFICATION
Lastly, verify is that the device is sending data to the correct server. This is a two-step process and
requires a user to be logged in FleetOutlook. First, force the device to send in an Ignition On event by
turning the ignition key to the forward position. Second, open the breadcrumb detail for the
corresponding vehicle in FleetOutlook. If the device is reporting properly, you should see an Ignition On
event on the Tracking | Breadcrumb Detail tab.
