Applies to RPMX-100U (38-GFX101-01) only
The projection lens is shipped with the internal focusing lenses optimally set for a
50" diagonal screen. This setting can be modified to suit other size screens (or
desired projected image size). Figure 10. illustrates the various settings available. It is
recommended that you choose a setting below 84" to achieve the best geometry and
focus. This procedure is only required during initial set up of the projector and is not
required each time you focus.
1. Power down the projector to perform this procedure. Press
2. Loosen the lock ring on the lens. (Figure 8.)
3. Grasp the projection lens by the barrel and turn counter-clockwise until it
becomes loose enough to remove.
4. Located near the end of the lens is the adjustment set screw (B) for geometry. See
Figure 10. for available settings.
5. Using a 1/16" ball driver, loosen the small lock screw (C ) near the 84" setting.
6. Using a 5/64" ball driver, loosen the adjustment set screw just enough so you can
slide it across to another setting.
7. Align the adjustment set screw to the desired setting and re-tighten. (It is
recommended you choose any setting under 84" to achieve the best geometry and
focus.)
8. Re-tighten the smaller lock screw near the 84" setting.
9. Slide the projection lens back into the PHM.
10. Re-tighten the lock ring.
