We are
told this has had the hydraulic conversion. The foot
pedal above controls rotation (manual) of the chair. The image
below shows the dual sets of switches that control the other functions
of the chair. The push
buttons control the auto-return to position function. Some of the white
buttons stay in position so you don't have to press them continuously
but you do have to return them to the middle position before you can do
anything else. The chair
moves up and down as shown above. The chair
tilts all the way back if needed. The headrest also tilts.
