Headband Adjustment

Comfortable Fit

Adjust the size (A) fig.1 and the height (B)

fig.2, so that the instrument is supported

comfortably around and on top of the head.

Ophthalmoscope Angle Alignment

For vertical alignment of the eyepieces and

binocular block (O), adjust the height of the

Metal Outer Brow Bar (C) if necessary

by using the browband tension knobs (D)

located on the sides of the headset (fig 3).

Position the Binocular Block (O) as close to the

eyes or spectacles as possible for maximum

field of view. Slightly loosen the ophthalmoscope

angle knob (E) to allow for adjustment and

tighten when in position as in (fig 4).

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.
