environment -guidance
Main power quality
should be that of a
typical commercial or
hospital environment. If
the user of the
BSVD-1000 system
requires continued
operation during power
mains interruptions, it is
recommended that the
Planmeca Emerald
scanner be powered
from an uninterruptible
power supply (UPS) or
a battery.
Power frequency
magnetic fields should
be at levels
characteristic of a
typical location in a
typical commercial or
hospital environment.
Portable and mobile RF
communications
equipment should be
used no closer to any
part of the Planmeca
Emerald scanner,
including cables, than
the recommended
separation distance
calculated from the
equation applicable to
the frequency of the
transmitter.
