Patient Headrest
There are two adjustment knobs for the patient headrest (see
• Headrest neck support adjustment knob—enables adjustment of the patient neck
support to provide patient comfort and to reduce patient head movement. Rotate the
knob clockwise to raise the patient neck support; rotate the knob counter-clockwise to
lower the patient neck support.
• Headrest vertical adjustment knob—enables adjustment of the patient head position to
provide patient comfort and to accommodate variation in patient head size. Rotate the
knob clockwise to lower the patient’s head; rotate the knob counter-clockwise to raise
the patient’s head.
NOTE
Before seating the patient, align the two arrows under the headrest neck support adjustment
knob. Use the headrest vertical adjustment knob to adjust the vertical position of the headrest
until the arrows are aligned.
The picture on the left shows the minimum allowable height of the headrest prior to beginning a
treatment. The headrest must not be adjusted lower than this position unless the system
becomes disabled for any reason during treatment and the headrest must be lowered to remove
the patient from the docked position.
