CalAmp | LMU-26xx Install Guide
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.
