2-2 Optical system (Layout Drawing)
2-2-1 Position of Chart Projector
The single tube projector must be installed at the same distance from
the screen as the patient.
[Fig. 3 Installation without mirrors]
Install chart projector at desired position within 2.5~8m (8~26 feet).
Set the projection angle of chart processor based on Screen.
Project 0.05(20/400, 6/120) “C” chart onto the screen.
Adjust it for a bright clear image using the focusing wheel.
2-2-2 How to obtain correct Letter Size and focus (Zooming Type only)
Install chart projector at desired position of 2.5~8m (8~26 feet)
Measure the distance from patient to screen
Refer to the test scale shown in the Appendix A
Have someone hold the test scale at the screen
Project the 20/400(6/120, 0.05) alphabet “C”
Adjust the position of the projector forward or backward and turn the focusing
wheel until “C” is brought in sharp focus within the respective distance scale

3-1 Inspection/adjustment procedures
3-1-1 Inspection items
① If the pilot lamp(green) lights when the power is turned on
② If the halogen lamp lights about 10 seconds after the power is turned on
③ If the entire chart is uniformly bright
④ If the remote control pilot lamp(orange) remains light when the CCP controller is in operation
⑤ If the CCP controller enables correct chart selection
⑥ Positional relationship between chart and mask
⑦ Auto shut-off function (Halogen lamp goes out after a some 10 minutes’ pause in operation.)

3-1-2 Inspection criteria
zPositional relationship between chart and mask
1. When a vertical line mask is used:
No right and left parts of the chart must be visible (when viewed from the correct position).
(Chart symbols must virtually align with the center of the mask.)
C

0.2
0.4
0.3
No adjoining parts of the
chart must be visible.
< Fig E4 >
2. When a horizontal line mask is used:
No upper and lower parts of the chart must be visible (when viewed from the correct position).
(Chart symbols must virtually align with the center of the mask.)
3. When a single isolation mask is used:
Only a single symbol must be visible with any other part of the chart staying invisible (when viewed from
the correct position).
(Chart symbol must virtually align with the center of the mask.)
4. When a red & green mask is used:
Boundary between the red and green parts of the mask must look straight with no tilt (when viewed from
the correct position).
