Whenever you adjust the height or turn the chair, make sure that the patient is not exposed to any
danger. Especially when adjusting the height of the Vito® patient chair, the seat shift and footrest are
a source of danger. Therefore, make sure that the patient always positions his or her feet on the
footrest.

the electromotive height adjustment.
After continuous operation of the height adjustment for 1.5 minutes, a cooling time of at
least 8.5 minutes must be observed.
If the height adjustment is operated continuously for longer than 1.5 minutes, this can lead
to a defect in the height adjustment.

It is forbidden to tilt the top of the chair if it does not have a safe flat surface or is not
connected to the optional docking station.
Unhitching the Vito® patient chair with an inclination of the backrest of more than 15° is not
permitted, as this may cause the Neo® patient chair to tip over during movement.
NOTE
!
Any change in the inclination of the backrest may only be made when the patient is safely
seated in the chair.
8.3 Footrest (optional)
The foldable footrest is fixed by a magnet so that it does not fold out by itself. If necessary, it can be
folded out by the user so that the patient can sit relaxed on the Vito® patient chair.

Safety system
A safety shut-off bar is fitted to each underside of a Block Optic examination unit to protect the
patient and prevent the patient's thighs from being pinched or crushed. Mechanical contact with the
safety bar will cause the patient chair drive to stop immediately. For more details, see the
instructions for a Block Optic examination unit.
NOTE
!
When using the Block Optic examination units, make sure that the patient rests his hands
comfortably on the armrests of the patient chair, as there is a risk of crushing at the headrest
holders!
When combining with products from other manufacturers, pay particular attention to the
safety requirements. The safety shut-off of the lifting function must be guaranteed.
Block Optic accepts no liability for improper use and any resulting damage.
