When adjusting the size of the image it is only necessary to adjust based on the
vertical portion of the image. When the image is sized vertically, it should also be
the correct size horizontally.

WARNING
Operating the WN-5220-V with access panels or the front screen removed can expose
service or operating personnel to intense light, high electrical voltages and hot surfaces.
Always wear ultraviolet-blocking eyeware with side guards when servicing the WN-
5220-V.
1. Attach the AC power cable
2. Remove the Lamp Access
Cover
Unfasten the 8 quarter-turn screws on the lamp access cover and
remove the cover
3. Re-install the screen (if it
is off)
4. Close the rear safety
interlock switch
Using a small wedge (made from a wire/cable tie, business card,
etc.), close the switch so that the display will operate without the
Lamp Access Cover on. Be careful not to damage the switch by
over-prying.
5. Turn the display on
Turn the power switch to the on position, wait for the three minute
standby-delay cycle and press the On button
6. Display a Geometry pattern
The built-in Geometry pattern won’t work in this application. You
need to be able to adjust the image up and down with the remote.
The built-in Geometry pattern can’t be moved with the remote.
Use a PC or other input source with displayed image similar to the
built-in Geometry pattern or use the Geometry pattern in Clarity’s
Diag software for Windows.
7. Find the upper edge of the
image
Adjust the image up or down using the remote until the upper edge
of the image is just touching the lower edge of the upper mullion.
The image is in the correct position when you can press the down
arrow button and the image shifts down, leaving a blank row next
to the mullion and when you press the up arrow button the edge of
the image is hidden behind the mullion.
8. Count the number of steps
to the bottom edge of the
image
Press the up arrow button one at a time and count the number of
steps until the bottom edge of the image is just above the top edge of
the bottom mullion.
9. If the number of steps is
less than 6 the image is too
small and needs to be
enlarged
Rotate the lens into the Optical Engine (clockwise) to enlarge the
size of the image. Repeat steps 7 through 9 until the image is
exactly 6 pixels taller than the viewable portion of the image on the
Screen.
10. If the number of steps is
greater than 6 the image
is too large and needs to
be reduced
Rotate the lens out of the Optical Engine (counter-clockwise) to
reduce the size of the image. Repeat steps 7 through 10 until the
image is exactly 6 pixels taller than the viewable portion of the
image on the Screen.
