7.3 Chair movement restrictors
Some dental unit parts are equipped with sensors that recognise when the
part is in its home position. When the part is not in the home position, chair
movements are disabled or restricted.
1. Bowl
The bowl is above the patient chair and slows down and restricts upward
chair movements. Return the bowl to its home position to resume normal
operation.
The home position is presented in section "Bowl" on page 23.
2. Armrests
When the armrests are turned outwards, all chair movements are
disabled. Turn the armrest inwards so that it is aligned with the chair to
resume normal operation.
3. Chair swivel
Depending on the chair swivel angle, the up-/downwards movements of
the chair and backrest might be restricted. Swivel the chair back to its
home position to resume normal operation.
The home position is presented in section "Chair swivel" on page 55.
