Compliance
Level
Floor should be wood,
concrete or ceramic tiles.
If floor is covered with
synthetic material, the relative
humidity should be at least
30%.
Mains power quality should be
that of a typical commercial or
hospital environment.
Mains power quality should be
that of a typical commercial or
hospital environment.
Mains power quality should be
that of a typical commercial or
hospital environment. If a
better mains power quality is
required, it is recommended
that the Gait Trainer 3 is
powered from an
uninterruptible power supply.
If image distortion occurs, it
may be necessary to position
the Gait Trainer 3 display
further from sources of power
frequency magnetic fields or to
install magnetic shielding. The
power frequency magnetic
field should be measured in
the intended installation
location to assure that it is
sufficiently low.
Portable and mobile RF
communications equipment
should be used no closer to
any part of the Gait Trainer 3,
including cables, than the
recommended separation
