• Describe the relevant things only in (Figure 4).
1. In the DCAM_PARAMETER, the DTL_Glain value is used for HeXa value.
For instance, if DTL_Gain=2631720 is translated into HeXa, it means 0x282828. So y=0x28, Cr=0x28 and
Cb=0x28.
2. In the LCD_Control, the settings are EVR value and also affect LCD output.
3. The Color Bar ON/OFF option can be used to display color bar with LCD and VIDEO OUT.
4. The Update option can be used to write the currently displayed number with EEPROM.
5. The Restore option can be used to restore to the first loaded value (EEPROM value before updating).
6. The Format option can be used to write the EEPROM default value saved in dscdtuio007.ini. of the
window folder.
("0xff" is the initially empty EEPROM value.)
Note) The Format is similar to the Format with LCD option without LCD control value.
7. The Reload option can be used to display the currently recorded EEPROM value on the screen.
*Note
- The model set value is 007 in the PGM mode. However, error occurred when 80 sets are connected to
adjust.
- Make sure that the testing model is the same with the running model in program.

5-1-1. Focus Adjustment
• Adjusting in the Photo Mode
1. Connect the camera and TV to video output cable. Turn on the power and set to the PC mode.
2. Aim the Main board at the focus chart placed 2.5 meters away and perpendicular to the center of the
lens.
3. Loose a fixing screw lightly positioned in front of a lever in the state of pulling back macro lever
toward °ƒ (counterclockwise at the front).
4. Turn the focus adjusting lever until a lever is in focus through the TV screen (not to move the macro
lever).
5. Tighten the fixing screw when the lever is in focus.
* In the Photo mode, the state of the focus may be difficult to check. If it isn’t, you can adjust in Resume
mode or with program for adjustment after taking a photograph.
• Adjusting with Program for Adjustment
* If the program for adjustment is used, the 3 times magnified screen allows you exactly to adjust camera.
1. Connect the camera to TV and PC with video output cable and PC connecting cable. Turn on the power
and set to the PC mode.
2. Aim the Main board at the focus chart placed 2.5 meters away and perpendicular to the center of the
lens.
3. After running the program for adjustment on the PC to click the Focus Mode On button in the Camera
Adjustment mode.
4. Repeat step 3 through 5 of “Adjusting in the Photo Mode”.
5. Click the Focus Mode On button and finish the program for adjustment.
