3-2 Camera Adjustment

Note :

1.This system has :

1)EEPROM to store the confirmed adjustment data.

2)DSP (Digital Signal Process ; ICP01 - Main board) chip to process the signal of camera parts.

3)The special mode for camera adjustment using the remote controller.

2.Keep in mind :

1)All adjustment steps should be performed using the remote controller.

3-2-1 Preparations

1. Equipment to be used :

1)DC Power supply

2)Oscilloscope

3)Frequency counter

4)Vectorscope

5)Waveform monitor

6)Color monitor or TV

7)Various charts

-Color bar chart

-Gray-scale chart, etc...

4. Remote control :

2. Composition of camera P.C.Boards :

1) Main PCB	2) CCD PCB
3) CVF PCB

3. Adjustment preparations :

1)Some buttons of set is used as a camera adjust tool.

2)Press the confirm button when each manual adjustment step is completed to write the adjustment data to the EEPROM.

3)After each adjustment step is completed, OSD shows “OK!”.

4)To cancel the adjustment mode, remove the power source.

The following is a chart explaining the use of each button :

1. Focus to zoom tracking

Notes : To maintain proper focus throughout the zoom range, the focus lens position must be changed as the zoom lens is moved.

During this adjustment the microprocessor will measure the focus positioning requirements at the wide and telephoto position of the zoom lens.

1)Camera “E-E”.

2)Focus chart (Attached on the last page of this manual).

3)Aim the camera at the focus chart placed 3 meters away and perpendicular to the center of the lens. The chart should be placed on the flat, gray or white wall.

4)Connect monitor TV jack to video output jack.

5)Press the “BLC(MODE UP)” and “FADE(MODE DOWN)” button, so that the OSD start is “0DE. 3M LENS XX XX”.

6)Press “ENTER(CONFIRM)” button.

The camera will move both zoom and focus lens.

The adjustment is finished when the O.K! message appears on the TV screen. Store the data to mode 099, 09A, 0AA, 0AB, 0AD, 0C9, 0CA, 0CB and 0CC.
