3.2.1 Power Supply Requirements

For the RA53/54 radar to be operated normally, the power supply (battery) detailed in Tab.3-2 is

required. Note also that if the battery is discharged, its voltage may fluctuate greatly, causing the radar

to malfunction. When to starting up the radar system or starting transmitting, an additional rush cur-

rent is required on the power supply line. Carefully check the power supply system including wiring by

using a circuit tester.
