Turning the System On and Off
The Power key is located in the bottom, left corner of the system console control panel.
Location of Console Power Key
Turn the System On
To turn the system on, press the POWER key, holding it down momentarily. You will hear a beep
when power is started. The system will take a number of seconds to boot up.
NOTE: While the system is booting up, do not try to power down.

ACUSON Freestyle User Manual 1-7
Introduction
Turn the System Off
To power the system down, press the POWER key, holding it down momentarily.
If you attempt to power the system down and the momentary pressing of the POWER key does
not shut the system off, hold the POWER key down continuously for ve seconds to power
down. If you repeatedly have problems powering down, contact your service representative.
NOTE: If the system does not boot up when it is not plugged into the AC Mains
power outlet, it may be because the system battery is depleted. Plug the system into
AC mains power outlet using the power cable.
WARNING: Do not power down until an archival transfer is complete. If the system
is in the process of an archival transfer operation, such as saving a patient study to a
removable storage medium or over a network, powering down will terminate the transfer
and result in an unsuccessful transfer.
CAUTION: Do not power down during a software upgrade. Powering down during a
system software upgrade will cause the upgrade to terminate and be unsuccessful.
