Chemicals

Handle chemicals of high volatility with care, use of which will affect to your health and environment.

1. Store them sealed in a specific place to prevent exposure to high temperature or direct sunlight.

2. Avoid dividing them into small containers and prevent vaporization.

3. Keep containers sealed when not in use.

4. Avoid using them as much as possible. When required, remove only required amount from the container to make full use.

Plastic parts

1. When cleaning plastic parts, use cleaning paper or cloth. Never use thinner, ketone, ether.

2. When installing plastic parts, insert the specific screws vertically to the parts. (Be careful not to tighten too much.

PCBs

Since PCBs use MOS IC, you must reduce static electricity. When repairing a PCB itself, or when wiring, please perform your work as illustrated below.

If grounding is impossible, connect a cable to a steel desk or shelf.

Keep touching the conductive mat while you work.

(2720)A 3

Discharge

Before disassembly, be sure to discharge the main condenser in the following manner. (Fig. 1)

Short-circuit with discharger or resistor of 200-300 ohm/3w.

Check voltage to make sure it is discharged.

Setting the camera and the chart when adjusting the CCD perspective.

Set the camera and the chart (siemens star chart and LB adjustment chart II for 2766) in either way, 1 or

2 of the followings to adjust the CCD perspective.

1. In case of using the camera chart setting stand

Required equipment

Camera chart setting stand

Stand for 2782

Chart stand backboard

Siemens star chart (see P.51 Measuring instrument)

LB adjustment chart II for 2766

Remodelling the camera chart setting stand

1. Exchange the stand for 2766 (Fig. 1 -1-).

2. Exchange the chart stand backboard (Fig. 1 -2-).

3. Move the board (Fig. 1 -3-) to 35cm back (Fig. 2).

Setting the camera and the chart

1. Install 2720 on the stand for 2782.

2. Stick the chart onto the chart stand backboard (siemens star chart or LB adjustment chart II for 2766), and adjust the base stand to be " 1670±30mm" for the distance form the CCD surface of the camera to the chart.

3. Turn the power of the camera on.

4. Look into the EVF, and adjust the base stand to let the chart be in the center of the finer.

Zoom roughly to let the vertical and horizontal spaces of the chart and the EVF finder be equal (Fig.3).

However, three adjustment screws for the CCD holder must be tighten to the end.

In case of using the camera chart setting stand on 2757 and 2765

Use the stand for 2757 / 2765 (Fig.1 -1-).

Move the board (Fig.1 -3-) to 35cm front (Fig.2).

36 (2720)A

2. In case of using a tripod

Required equipment

Tripod

Siemens star chart (see P.51 Measuring instrument)

LB adjustment chart II for 2766

Setting the camera and the chart

1. Mark in the center of the chart (siemens star chart or LB adjustment chart II for 2766) (Fig.1).

2. Stick the chart onto the wall.

3. Check the point where the straight line from the center of the chart, "marking" meets the floor surface

(Fig.2).

4. Stick the line or tape measure in the angle of "90 degrees" from the checked point on the floor to the chart (Fig.2).

5. Align the heights of the center of the chart and the camera lens (Fig.2).

6. Align the line of the floor and the center of the camera lens to set the distance, from the CCD surface of the camera to the chart, to "1670•} 30mm" (Fig.2).

7. Turn the power of the camera on.

8. Look into the EVF, and adjust the camera to let the 2 charts be in the center of the finder.

Zoom roughly to let the vertical and horizontal spaces of the chart and the EVF finder be equal (Fig.3).

However, three adjustment screws for the CCD holder must be tighten to the end.

9. When 5, 6 and 8 are aligned, the setting of the camera and the chart is completed.

Align the hights of the center of the chart and the lens.
