3-2 Camera Adjustment

Note : How to adjust the camera system.

1) EEPROM stores confirmed adjustment value of each adjustment step.

2) DSP (Digital Signal Process : ICM01-Main PCB) digitalizes the camera signal.

3) When changing IC505-Main PCB of EEPROM, readjust Main PCB. While changing LCD PCB and CVF PCB- always readjust each part.

Since EEPROM stores confirmed adjustment value of each adjustment step, readjusting must be performed in order

to store the changed data.

4) Adjust the following items after changing LENS Ass’y.

Œ Lens Zoom Track ´ Auto HALL ˇ Auto IRIS

5) Adjust the following items after changing EEPROM and Camera Main PCB.

3-3-3 Maintenance

Carry out the following periodic maintenance checks in order to fully exercise all functions, operations and tape. After repairing, service the set as follows:

1) Cleaning of Drum Assembly

Œ Gently apply lens tissue soaked in ethyl alcohol to the Drum assembly.

Clean the Upper Drum assembly while rotating it slowly counterclockwise(by hand).

Note : Do not rotate the motor by power or rotate the Upper Drum assembly clockwise.

Also, the Head tip will be damaged if the lens tissue is moved in a perpendicular direction.

Be sure to follow these instructions when cleaning the Drum Ass’y

2) Cleaning of Tape Path

Œ In EJECT mode, clean the tape path system(from Pole Tension P1 through Pole Review P9, Pinch Roller and

Capstan Shaft) and the Lower Drum. Using the lens tissue soaked in ethyl alcohol.

Note : Make sure that no oil or grease adheres to the lens tissue.
