releasing the manually operated lock that is located on the doctor's side of the chair at
the base of the pedestal. The purpose of the base (lift) motor assembly is to raise and
lower the chair. This is done in one of the following three ways.
By using the foot switch, located on the pedestal.
(2) By using the three-position switch on the bottom of the assistant's
controls (the left side of the chair as viewed from the back).
(3) By using the bottom switch on the doctor's controls (the right of the chair
as viewed from the back). This switch is for automatic operation only. There are three
functions: raise, tilt, and recline.

(3) The bottom switch is for automatic operation. Depressing the automatic
operation switch will recline, tilt, and raise the chair, all at the same time. This multi-
directional function is referred to as operate. Depressing the switch downward will bring
the chair to the upright and lowered "exit" position.
