1) Verify that the ultrasound unit has been connected to the power supply and that the circuit breaker
is ON, as described in
3-6-5-2 "Connecting the Ultrasound Unit to the Electrical Outlet" on page 3-

performs an initialization sequence which includes the following:
•
Loading the operating system.
•
Running a quick diagnostic check of the system.
•
Detecting connected probes.
The system first enters 2D-Mode with the probe and application that were last used before the system
was shut down. If the probe has been removed since the system was last used, the currently connected
probes and their available applications are displayed and selected by default.
NOTICE
Disconnecting the Mains Power Cable
before
switching OFF the Circuit Breaker will activate the
uninterruptible power system (UPS) in the back-end processor, forcing an ordered shutdown of the
system.

On/Off
button on the control console illuminates amber,
indicating the Back-end Processor is in
Standby
mode.
