ESD precautions must be 
observed to prevent the Edge 
ultrasound system from 
shutting down during 
operation. If the system shuts 
down, turn it on again to 
restore normal operation. 
See also “Electrostatic 
discharge” on page 104.

Mains power quality should 
be that of a typical 
commercial or hospital 
environment. If the user of 
the Edge ultrasound system 
requires continued operation 
during power mains 
interruptions, it is 
recommended that the Edge 
ultrasound system be 
powered from an 
uninterruptible power supply 
or a battery.
Guidance and Manufacturer’s Declaration - Electromagnetic Immunity (continued)
The Edge ultrasound system is intended for use in the electromagnetic environment specified 
below. The customer or the user of the Edge ultrasound system should assure that it is used in 
such an environment.
