Precautions

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.

Adjustments and Checks Required After Repair

After making replacement or repair of the following items, check or adjust as required in the table.

Be sure to perform in a sequential order from the top in the table.

: Necessary check : Necessary adjustment

Adjustment sequence

Some adjustments should be performed in the order

1.Lens Adjustment

Note of the PW-1 Compl PWB (#0432,0452)

Never turn the VR501 and VR502 on the PW-1 Compl PWB (#0432,0452), or the PW-1 Compl PWB

(#0432,0452) has to be replaced.

The output voltage adjustment and the oscillating frequency adjustment of the individual PWB can only

be performed at the parts assembly line, not available with service facilities.

For the same reason, always replace with the PW-1 Compl PWB (#0432,0452) as a set.

USB Storage Information Registration

For USB to work, you must input the correct USB storage information to the camera (#2786).

Otherwise, problem may occur while the camera is connected to the computer via USB cable.

Always ensure that the USB storage information after repairing it .

Whenever after replacing the CP-1 Compl PWB (#0408), be sure to perform the USB storage information

registration.

Caution

Be sure to confirm the USB Storage Information is displayed as above. Once any wrong information is

registered, cancellation is impossible. Especially, "VID" and "PID" are important to connect the camera

to the computer. If the information is wrong, the camera cannot be activated in adjustment mode. In

this case, replacing the CP-1 Compl PWB (#0408) is required.
