OPERATION PROCEDURES
(4) Interpupillary distance adjustment
While looking through the eyepieces at the image on the focusing test rod, adjust the converg-
ing binocular's prism box, so that the image is fused and a stereo-scopic image results. For
operator comfort, since each eyepiece can be moved independently, insure that both eye-
pieces are at the same height.
PATIENT POSITION
Positioning patient's head
Have the patient place his chin on the chinrest and forehead against the forehead rest. Adjust the
chinrest adjuster so that the patient's outer canthus is at the approximate height of the canthus
marker.
BASE OPERATION
(1) Horizontal gross adjustment
To adjust the microscope's position horizontally, move the base while keeping the joystick in
the vertical position.
(2) Horizontal fine adjustment
For fine adjustment, such as alignment or focusing, tilt the joystick to the left or the right.
(3) Vertical fine adjustment
For fine vertical adjustment, turn the joystick clockwise to raise the microscope and counter-
clockwise to lower it.
