Mains power quality should be that of a
typical commercial or hospital
environment. The unit continues to operate
during a 5-second loss of power. However,
if the user of the Terason Ultrasound
System requires continued operation
during a longer power outage, Using an
uninterruptible power supply to power the
Terason system is recommended.
