Mains power quality should be
that of a typical commercial or
hospital environment. If the user
of Planmeca Proline EC X-ray
unit requires continued operation
during power mains interruptions,
it is recommended that Planmeca
Proline EC X-ray unit be powered
from an uninterruptible power
supply.

Power frequency magnetic fields
should be at levels characteristic
of a typical location in a typical
commercial or hospital environ-
ment. The power frequency mag-
netic field should be measured in
the intended installation location
to assure that it is sufficiently low.
