Packaging
Anytime the sub assembly is shipped and it is not fully packaged in its final housing it must be sealed in an
ESD safe bag.
Electrical Over-Stress (EOS)
The 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-2600™ GPS Antenna to another LMU-2600™ 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-2600™ GPS Antenna should be kept at least four inches apart from any active
LMU-2600™ GSM Antenna or any other active high power RF transmitter with power greater than 1 Watt.
3.1.2 Battery Back-up devices
Please properly dispose of the battery in any of the CalAmp products that utilize one, do not just throw used
batteries, replaced batteries, or units containing a back-up battery into the trash. Consult your local waste
management facility for proper disposal instructions.
3.1.3 Environmental Specifications
The LMU-2600™ 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-2600™ 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 is designed to operate in and the relevant SAE
tests that were performed. No formal altitude tests were conducted.
