Lens Replacement

Replacing Lenses in Auxiliary Dial - Old Style Phoroptors

Five lenses in each dial are cell mounted: the retinoscopic, polarizing, both Maddox rods, and fixed

cross cylinder lenses are in individual cells permitting

substitution

of special lenses. Two washers

and screws retain each cell. Refer to Figure MM-5.

To remove cell from dial:

1. Turn the Auxiliary Dial Knob until one of the

two retaining screws is visible in the rear of

the main aperture.

2. Turn the screw 1/4 turn counterclockwise-

not remove

- until the washer can be rotated

to place the flat side of washer toward the cell.

3. Gently retighten the screw.

4. Turn the knob until the other screw and

washer are visible in the aperture.

5. Repeat the preceding step.

6. Next, turn the knob to center the cell in the

aperture.

7. Gently press the cell out of the auxiliary dial

thru the rear of the aperture.

8. The procedure is reversed to install a new cell

mounted auxiliary lens.

9. Make certain that the “notches” in the cell are

positioned to permit entry of retaining washers.

10. To lock new cell into position: turn the screw 1/4 turn; rotate washer so that flat side is 90

away

from cell; tighten the screw firmly.

11. Repeat for the other screw and washer.

Replacing Lenses in Auxiliary Dial - New Style Phoroptors

New style Phoroptors do not have washers. The washer and screw is replaced by a single, magne-

tized screw. Refer to Figure MM-6.

To remove cell from dial:

1. Turn the Auxiliary Dial Knob until one of the

two retaining screws is visible in the rear of

the main aperture.

2. Unscrew the retaining screw and remove it.

3. Turn the knob until the other screw is visible

in the aperture.

4. Repeat the preceding step.

5. Next, turn the knob to center the cell in the

aperture.

6. Gently press the cell out of the auxiliary dial

thru the rear of the aperture.

7. The procedure is reversed to install a new cell

mounted auxiliary lens.

8. To lock new cell into position, tighten the

screw firmly.

9. Repeat for the other screw.
