(Power-on switch)
Mains power quality should
be that of a typical
commercial or hospital
environment. If the user of
the ultrasound unit requires
continued operation during
power mains interruptions, it
is recommended that the
ultrasound unit is powered
from an uninterruptible
power supply or a battery.
