4-2-2-2 Turning the System ON
1) Verify that the ultrasound unit has been connected to the mains power wall outlet via the AC
connector on the rear of the system (as previously described) and that mains power is turned ON.
2) Hold down the On/Off
button (Figure 4-4 "On/Off Button on Control Panel" on page 4-5) on the
control panel for 3 seconds.
The system automatically performs an initialization sequence that includes the following:
• Loading the operating system.
• Running a quick diagnostic check of the system.
• Detecting connected probes.
During normal boot-up, you may observe that:
a.) The unit’s ventilation fans start on full speed, but slow down after a few seconds (listen to the
fan noise).
b.) Power is distributed to the peripherals, Operator Panel (control panel), Monitor, Front-End
Processor and Back-End Processor.
When AC power is applied to the scanner and circuit breaker is ON, the On/Off button on the control
console illuminates, indicating the Back-end Processor is ready for boot-up.
