the A&D unit requires
continued operation during
power mains interruptions, it is
recommended that the A&D
unit be powered from an
uninterruptible power supply or
a battery.

Power frequency magnetic
fields should be at levels
characteristic of a typical
location in a typical
commercial or hospital
environment.
NOTE : U
