9 Loosen the barrel screw

about a half of a turn with

the attached hexagonal

wrench.

Move the knob in the arrow

direction so that the projec-

tion on the screen is sharp

and clear. For proper cali-

bration, the projection of the

chart which has 0.1 (or 20/

200) visual acuity should

contact the inner side of one

of the scales on the cal ibra-

tion card which correspon-

dis to the desired refracting distance.

Barrel screw Knob

10 If the size does not match the respectiv e refracting dis tance scale, move the instr u-

ment either toward or away item the screen and then repeat items 9 above.

11 Fix the bar rel screw to complete preparation.

13

Operation procedures

For R type (variable focus lens type)

12 Loosen the first lens-barrel screw and the second lens-barrel screw about a half of a

turn.

Move the lens-barrel screw

in the arrow direction with

the hexagonal wrench

inserted.

The first lens-barrel screw:

size

The second lens-barrel

screw: focus

Move the first lens-barrel

screw to roughly fit the size

and move the second lens-

barrel screw to achieve the

focus.

13 Move the first an d second lens-barrel screw for-

ward and/or backward to focus 20/200 (or 0.1)

visual acuity "E" on to the projection screen.

Place the calibration card on the projection

screen. The "E" of the 20 /200 sl ide s hould fi ll an d

just touch the inner sides of the scale which corre-

sponds to the desired refracting distance.

* The variable focus lenses permits the R type to be positioned at the following projec-

tion distances relative to refracing distance:

Refracting Distance Projection Distance

3m 2.90 to 3.70m
4m 3.80 to 4.80m
5m 4.70 to 5.90m

6.1m 5.70 to 7.10m

For example:

At a refracting distance of 5 meters, the R type Au to Chart Pr ojec tor ca n be pos i­tioned at a distance of 4.70 to 5.90 meters. Withi n this range, th e variable focus
objective lenses can project the properly calibrated image.
