TO AVOID ELECTRICAL SHOCK, THE ULTRASOUND SYSTEM UNDER TEST MUST NOT
BE CONNECTED TO OTHER ELECTRICAL EQUIPMENT. REMOVE ALL

Energy Control and Power Lockout for Vivid™ S60/Vivid™ S70.
When servicing parts of the Ultrasound system where there is exposure to voltage greater
than 30 volts:
1. Follow LOCK OUT/TAG OUT procedures.
2. Turn off the breaker.
3. Unplug the Ultrasound system.
4. Maintain control of the Ultrasound system power plug.
5. Wait for at least 30 seconds for capacitors to discharge as there are no test points to
verify isolation.
Ultrasound System components may be energized.
Possible risk of infection. Do not handle soiled or contaminated probes and other
components that have been in patient contact. Follow appropriate cleaning and disinfecting
procedures before handling the equipment.
For all instructions in the "Electrical safety tests" section, in the event of using a UPS
(uninterrupted power supply) the terms outlet, wall outlet, AC wall outlet and power outlet refer
to the AC power outlet of the UPS. In case of further available AC (or DC) power outlets at the
same used UPS, these must remain unused i.e. not connected to any other devices.
