• Raise the leg support:
The chair movement stops, then there is a corrective
movement upwards for around 3sec.
• Raise the backrest:
The backrest movement stops, then there is a correc-
tive movement upwards for around 3sec.
• Raise the motor-adjustable headrest:

tive movement upwards for around 3sec.
• Swing in the swiveling cuspidor (optional):

ATTENTION
If one of the safety switches does not stop the chair
movement or the backrest movement, the treatment
center must not be used for dental work!
