To ensure proper operation in such an environment, the 4530™ 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.
