Optional Battery Operation
The ultrasound system operates using the AC input power. The
batteries are not intended for imaging or sustained system operation.
The main benefits of the batteries are not having to shut down for
transport and having time for normal shutdown in the event of
unexpected power failures.
The functions provided by the optional batteries are:
 Ensure proper system shutdown in the event of an unexpected
AC power loss.
 Provides 20 minutes of 24VDC power for quick system startup
and system transport. After 20 minutes the system will undergo
normal OS shutdown.
