Interpupillary Distance Setting Control (S)
Because the eyes are dissociated, particular care must
be taken to ensure the optics (eyepieces) are set properly
in front of each eye.
Always set the Aperture Selection (H) to the large light
patch for this exercise.
Place an object, perhaps the thumb, approximately 40cm
from the face and centre it horizontally in the light patch.
Then, close one eye. Using the thumb and forefinger of
the opposite hand, slide the P.D.Control (S) of the open
eye (located directly under each eyepiece) so that your
object moves into the centre of the field, keeping the object
in the centre of the light patch. Repeat for the other eye.
Obtaining a Fused Image
Ensure that a singular, fused image is obtained as follows:
Mirror Angle Control (J)
The light is positioned vertically into the upper two thirds
of the field of view by rotating the spindle (J) located on
either side of the binocular block.
Head Dimmer Switch (T)
Turn the illumination on by rotating the headband dimmer (T)
in an anti clockwise direction.
