Ensure correct and comfortable headband fit
Adjust the top and back adjusters (A&B) so that the
indirect is supported comfortably, as shown in fig 1&2.
Position the brow bar (E) such that the viewing box is
set on the optical axis.
The brow bar may be correctly positioned by loosening
(F) the brow bar adjusters. When in the correct position
secure by tightening (F) as shown in fig 3.
Position the All Pupil II as close to the eyes as possible
for maximum field as shown in fig 4. by using the hinge
adjuster (D) as shown in fig 5.

Interpupillary Distance Adjusters
Because the eyes are dissociated, particular care must
be taken to ensure the optics are set properly in front of
each eye. Always set the aperture selector to the
largest patch of light. The interpupillary distance
adjusters are located directly beneath the viewing box.
They are adjusted independently of each other. 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 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 single, fused image is obtained as follows:-

Headband Rheostat
To operate your headband dimmer
turn the rheostat to the illumination
required.

Adjustment for Mirror Height
By adjustment of the mirror
alignment control (I) the light
beam may be positioned to any
vertical height within the viewed
area.
Select Aperture Control Lever
The Aperture Control Lever (G)
changes the aperture size to
view through large, medium and
small pupils.
Select either large, medium or small aperture by
adjusting lever from left to right - small - medium -
large.
Large Aperture - Suitable for routine examinations
through fully dilated pupils
Medium Aperture - Reduces reflections when entering
a partially or poorly dilated pupil (3mm). It is also ideal
for closer inspection of particular fundal areas.
Small Aperture - Ideal for small, undilated pupils

Built in Filters
Select filter or diffuser by
sliding filter selector bar (H)
either side of the All Pupil II.
Red Free Filter - This filter reduces red light, so blood
will appear black, silhouetted against a dark
background
Diffuser - Providing extra wide beams of light that can
be used with all aperture sizes.
The instrument provides protection from UV/IR.

Teaching Mirror
The teaching mirror is fitted as follows:-
A. Remove the screws from the
panel beneath the front window
with the screwdriver supplied.
(fig 6)
1. Fit the mounting bar with the pin
pointing to the right and secure
with screws removed in step (A)
(fig 7). Slide the teaching mirror
onto the pin on the mounting
bar. The teaching mirror can
now be swivelled up and down.
2. To remove, slide the teaching
mirror to the right of the pin and
return to its case leaving
mounting bar in position
B. To make the teaching mirror Non-Removable for
security purposes proceed as follows.
1. Remove the screws as in fig 6 above. Position the
mounting bar and replace the screw on left side only. Fit
the teaching mirror as in fig 7.
2. Fold the Teaching Mirror down
and slide it to the right to reveal
fixing hole. Then secure the
mounting bar with the special
washer and pan head screw
provided. (fig 8)
3. Return the teaching mirror to its
central position.
4. The teaching mirror can now be demounted only by
removing the screw. Retain the screwdriver for future
use.

It is well established that exposure of the eye to intense light sources
for extended periods of time poses a risk of retinal photic injury.
Many ophthalmic instruments illuminate the eye with intense light. The
decision about the intensity of light level to use in any procedure must
be made on a case by case basis. In each case, the clinician must take
a risk benefit judgement about the intensity of light to be used. Use of
insufficient intensity may result in inadequate visualization and in
adverse effects more serious than a retinal photic injury. Further,
despite all efforts taken to minimize the risk of retinal damage, damage
may still occur. Retinal photic injury is a possible complication of the need
to use bright light to clearly visualize ocular structures during deli-
cate ophthalmic surgical procedures.
While no visible retinal photic lesions have been identified for
ophthalmic instruments, it is recommended that illumination levels be
set to the minimum level necessary to perform the diagnostic function.
Young children and persons with diseased eyes may be at a higher risk.
The risk may also be increased if the person being examined has had
any exposure with the same instrument or any other ophthalmic
instrument using an intense visible light source during the previous 24
hours. This will apply particularly if the eye has been exposed to retinal
photography.
The time to reach a potential optical radiation hazard for this device is 3
minutes when the instrument is being operated at maximum intensity
and maximum aperture. This time is for a cumalative exposure in a day.
It should be noted that there is a safety factor of about 10 built into the
safety guidelines. Hence, for a source with continuous light output, if the
exposure time is 100s, photoretinitis might be expected for an exposure
time of 10 x 100s = 1000s (about 17 minutes).
