4-9-1 Forced formatting of DVD-RAM disc

(1) Application/Symptom

Perform this procedure when the Disc Navigation screen does not start normally due to a defect in data on disc and formatting is not possible by the procedure explained in instruction manual.

(2) Operational procedure

Caution:

1)Initialization will delete all data on disc: Copy the necessary files to PC, etc.

2)Do not turn power off or remove the disc during initialization: Such an interruption will make the disc unusable.

1)Connect the AC adapter/charger, and set the power switch to “VIDEO” or “PHOTO”.

Be sure to use the AC adapter/charger for formatting disc: If power is interrupted during work, the disc could become unusable.

2)Make sure that the DVD-RAM disc to be formatted is free from dirt or scratch. If the disc is dirty, clean it; if the disc is scratched, replace it. Any dirt or scratch on disc could disable normal formatting. (Fig. 4-9-1)

3)Insert the DVD-RAM disc to be formatted.

4)After the disc is recognized, operate the following buttons to display the disc formatting screen (Fig. 4-9-2):

Hold down the SELECT, REC and + (plus) buttons simultaneously for at least 3 seconds

5)Use the joystick to choose “YES” and press the center of joystick:

The initialization will start and message “Formatting ...” will appear.

6)When formatting is complete, message “Finished” will appear for several seconds, and then the normal screen will automatically be restored.

Use soft cloth to clean from inner to outer circumference in axial direction.

[Never use solvent.]
