Mains power quality should be
that of a typical commercial or
hospital environment. If the user
of the Welch Allyn CardioPerfect
Pro Cardiograph requires
continued operation during
power mains interruptions, it is
recommended that the Welch
Allyn CardioPerfect Pro
Cardiograph be powered from an
uninterruptible power supply or a
battery.

Hz) magnetic field
IEC 61000-4-8 3 A/m 3 A/m Power frequency magnetic fields
should be at levels characteristic
of a typical location in a typical
commercial or hospital
environment.
