c. Seat Motor Assembly. The seat motor is used to tilt the seat of the chair up
or down. It is located at the front of the chair in the center. The seat can be adjusted by
the doctor's center switch or the assistant's lower switch on either side of the chair back.
d. Back Motor Assembly. The back motor is used to recline or tilt the back of
the chair up. It is located at the front right of the cradle assembly as viewed from the
rear. The back can be reclined or tilted up using the switches located at the top of
either the doctor's or the assistant's side of the chair.
e. Doctor's Controls. Refer to figure 1-1. The doctor's controls are located on
the back rest on the right side of the chair as viewed from the back.
The uppermost switch is the back adjustment.
The center switch is for the seat adjustment.

downward returns the chair to the "exit" position. It lowers the chair completely; it raises
the back, and tilts the seat forward.
f. Assistant's Controls. Refer to figure 1-1. There are two switches located
on the assistant's side (left) of the chair back.
(1) They have the same function as the doctor's corresponding controls with
the exception of the doctor's lowermost switch, for which the assistant has no match.
(2) Additionally, the AUTO/MANUAL mode toggle switch is located under
the chair on the assistant's side at the front of the chair. The doctor's lowermost switch
only operates if this toggle switch is set to AUTO.
g. Pedestal Controls. Refer to figure 1-1. There is one foot switch at the rear
of the chair that can be operated from either side.
It manually raises and lowers the chair.
(2) When operated from the doctor's side, pushing the foot switch forward
raises the chair.
(3) When operated from the doctor's side, pushing the foot switch to the
rear lowers the chair.
