Section IV Operation
Base Lowering Safety Switch
The NuSimplicity Chair is equipped with a base
lowering safety switch. This feature ensures
nothing gets caught underneath the chair base as
it is lowered.
The following describes how this feature operates:
1. When the base cantilever section is lowered
and contacts an obstruction, the cover on the
underside of the cantilever section will move
upward and activate the chair safety switches.
2. Downward motion of the base will stop, and
the base will start moving upward immediately
while the chair emits a constant, short warning
beep.
3. Moving the base up and o of the obstruction
deactivates the safety switches and silences
the warning beep.
If any auto position buttons are pressed, the chair
will sound three short beeps to indicate auto
positioning is not available.
The NuSimplicity Chair is capable of swiveling 30° to
either side of its center position.
To swivel the chair:
1. Release the chair brake located on the back
of the chair seat casting by moving the brake
handle completely to the right (Figure 23).
2. Swivel the chair to the desired position.
3. Lock the chair brake by moving the brake
handle to the left.
