2-2 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.

2-2-1 Preparations

4. Remote control :

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

1. Equipment to be used :

1) DC Power supply

2) Oscilloscope

3) Frequency counter

4) Vectorscope

5) Waveform monitor

6) Color monitor or TV

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.
