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.

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.
