Mains power quality should be that of a typical
commercial or hospital environment. If the user or
the SP-1P requires continued operation during
power mains interruptions, it is recommended
that the SP-1P be powered from an uninterrupt-
ible power supply or battery.

Power frequency magnetic fields should be at
levels characteristic of a typical location in a typi-
cal commercial or hospital environment.
