the power harness. The MP modem supports a voltage range between 9 volts
direct current (VDC) and 36 VDC, and is designed for both 12 VDC and 24 VDC
vehicle electrical systems.
Note: Electrical installations are potentially dangerous and should be performed by
personnel thoroughly trained in safe electrical wiring procedures for vehicles.
