the RPA are located closest to the projector
lens. Do not remove the screws and
washers from the second set of slotted holes
on the RPA.
1. On the RPA, remove two screws from the first set of
slotted holes on the RPA. See Figure 4.

2. Remove the two center screws from the RPA.
3. On the NAV-1, loosen the two screws on each side
to allow the bracket to extend backward and forward.
4. Slide the NAV-1 over the RPA projector mount, as
shown in Figure 5.
5. Align the slotted holes on the NAV-1 with the slotted
holes on the RPA. For reference, see step 1.
6. Locate the parts bag supplied with the NAV-1. Find
four 5/8” screws (80) and four #10 washers (90).
NOTE: Leave the four screws (80) loose. These
screws will be adjusted and tightened later.
7. Attach the NAV-1 to the RPA by installing four

6-1/4 inches
3-1/5 inches up and down on front lens
plate.
Refer to Figure 10 and adjust the NAV-1 lens to the RPA
projector lens, as follows:
Pitch Adjustment
1. To adjust lens pitch, adjust the two angle screws to
raise or lower the lens. This adjustment aligns the
conversion lens with the projector lens.
Extension Adjustment
2. To adjust lens extension (raise or lower the lens), do
the following:
a. Loosen four screws (30) and washers (90) on
the side of the front adjustable plate (20).
b. Slide the front adjustable plate (20) back so the
lens is approximately 1/8” to 1/4” from the
projector lens.
Lateral Shift Adjustment
3. To adjust lateral shift, do the following:
a. Loosen the knob (60) and slide the lens left or
right to the center of the projector lens.
b. Tighten the knob (60).
Height Adjustment
4. For height adjustment, do the following:
a. Loosen the knob (60) and slide the NAV-1 lens
up or down.
b. Tighten the knob (60).
Adjustment Notes
NOTE: Except for fine-tuning, the NAV-1 is adjusted
after completing the adjustment process.
However, after restoring power to the projector,
you may want to repeat a particular adjustment
procedure in order to make minor changes.
NOTE: Depending on your projector model, it may be
necessary to adjust the lens at a slight angle to
the projector lens, which helps to correct
keystone.
NOTE: If you have difficulty with the lens alignment,
contact Navitar Inc. Call Navitar’s Customer
Service Department at: 1-800-828-6778.
c. Tighten the four screws (30) and washers (90).
