Installation
The AP250 should be installed according to the
following procedures.
1. If using a wall mount, it is best to locate a wall stud
to support the projector’s weight. Install the wall
mount with appropriate hardware for the type of wall
it is being installed on.
2. The following distances are important in the set-up
of a refracting room:
REFRACTING DISTANCE (RD)
The distance from the patient’s eye to the screen.
PROJECTION DISTANCE (PD)
The distance from the slide to the screen.
LETTER HEIGHT (LH) The height of a 20/200
character should be equal to the refracting distance
times the tangent of 50 minutes of arc or .014545.LH
(inches) or (mm) = RD (inches) or (mm) x .014545
For example, a refracting distance of 240 inches (20
feet) will require a 20/200 height of 3.49 inches (240
inches x .014545 = 3.49 inches) or for a 4000 mm (4
m) refracting distance, you will require a letter height
of 58.18 mm (4000 mm x .014545 = 58.18 mm).
3. Determine the refracting distance by measuring the
distance from the patient to the screen. Please refer
to Figures 1 and 2, below, which show combinations
of refracting and projection distances achievable
with this system.
4. Install the projector screen.
5. If attaching the AP250 to a mount, loosen the clamp-
down screw (see page 6, #6) and insert the projec-
tor mount onto the ball. Tighten screw, allowing for
some movement of the projector for final positioning.
Fully tighten the screw after final adjustment and
alignment of the system.
6. Make sure the voltage indicator number corresponds
with the available local mains.
7. Plug power cord into AC inlet and into a wall power
outlet. Set the power switch to the “ON” position.
Note: For proper operation, the remote typically
needs to be more than 5 ft (1.5 m) away from
the projector. Make sure no objects that
could interrupt remote control signals are lo-
cated between remote control and projector.

110V/230V Operation
To ensure proper operation, check the fuse voltage setting on the power input mod-
ule. The factory setting is 110 V. If 230 V operation is desired, remove the fuse
holder and pull out the white plastic insert Refer to Figure 3. Rotate the insert so
"230" appears in the window when inserted in the fuse holder. Remove the 500 mA
fuses and replace them with 250 mA fuses. See page 14 for fuse types. Install the
fuse holder in the power input connector.
Alignment & Focusing
WARNING: PROPER SETTING OF THE FOCUS AND DISTANCE CONTROLS REQUIRES THAT THE PROJECTOR
COVER BE OPEN WHILE THE INSTRUMENT IS PLUGGED IN AND TURNED ON. UTILIZE ONLY THE DISTANCE
AND FOCUS CONTROLS WHILE THE COVER IS OPEN. DO NOT TOUCH ANY OTHER COMPONENTS UNDER
THE COVER OR PERSONAL INJURY MAY RESULT.
The AP250 can be optimally focused at projection distances between 10 ft (3 m) and 26.5 ft (8 m) when the patient and
projector are equidistant from the projection screen.
1. Project a 20/200 or 0.1 character onto the screen by pressing the key.
2. Check the three-dimensional alignment of the sys-
tem.Tooptimizethealignment,itmaybenecessary
to angle the screen to direct light towards the pa-
tient’s head. As a test, place a mirror on the screen.
The light should project where the patient's head
would be (see Figure 3).
3. Adjust the image positioning on the screen. It may
be necessary to adjust the projector and the screen.
Secure projector by tightening mounting screw.
4. Determinetheproperlettersizebasedontherefract-
ingdistanceused.RefertotheLetterSizingCharts
at the end of this manual.
5. AttachLetterSizingCharttothescreen.
6. Open the projector cover by removing the hexagon
screw under the front of the AP250.
7. Move the AP250's focusing controls (see page 5, #
11 & 12) until the 20/200 or .01 "Z" is in sharp focus
andfillsthebracketontheLetterSizingChart,as
shown in Figure 3.
Note: To obtain longer refracting distances in
small rooms, a mirror or system of mirrors
can be used. A high quality front-surface
mirror is required. See Figure 4 as an ex-
ample of a short room with a full refracting
distance of 20 feet.
Note: To prevent interference with the operation
of the Remote Control window, care should
be taken not to position any bright lights
directly toward the front of the AP250.
