Adjustment > Adjustment Procedure 6-4-9 Stabilizer Note: Perform STABILIZER only after replacing any component on the GYR circuit board or executing “Data Initialize”. This item STABILIZER is not an adjustment, but is performed to write the camera shake correction value contained in adjustment program to EEPROM. Although the camera shake correction value written to EEPROM is an adjustment value inherent in individual devices when shipped from the factory, the camera shake correction value contained in adjustment program is an average value set at the factory.
Adjustment > Adjustment Procedure 6-4-10 Spot Noise Information: 1) The SPOT NOISE adjustment compensates for bright points that appear on the screen, and these are caused by a defect in pixel of CCD (image sensor) that may occur when DVD video camera/recorder is used under particular conditions or for a long time.
Adjustment > Adjustment Procedure 6-4-11 LCD Note: 1) Perform LCD only after replacing the MAN circuit board or 2.5 LCD Unit, or executing “Data Initialize”. 2) Neither light box nor chart is needed for LCD adjustment. Before performing any adjustments for LCD, be sure to shift the DVD video camera/recorder to the test mode using the procedure below, and then display the LCD ADJUSTMENT MENU.
