Pressing buttons PLAY, RETURN and TOP MENU in same time at the unit. Service mode menu will be display. Select menu by
cursor button and press ENTER button to activate the service modes.

When cleaning the lens, use the lens cleaner which product part No. SZZP1038C.

• When EEPROM or main P.C.B. is replaced, carry out the recovery processing to optimize the drive.

Playback the recovery disk to process the recovery automatically.

• Recovery disc (Product number: RFKZD03R005)
• Performing recovery

1. Load the recovery disc RFKZD03R005 on to the player and run it.
2. Recovery is performed automatically.  When it is finished, a message appears on the screen.
3. Remove the recovery disc.
4. Turn off the power.

This unit requires no initialization process carried out after the traditional DVD players were repaired.
When the recovery measures are taken, the customer setting will return to the factory setting. Write down the contents of the
setting before recovery processing, and reset the player.

• The firmware of the DVD player may be renewed to improve the quality including operation ability and playability to the substan-

dard discs.processing to optimize the drive.
The recovery disc has also firmware version-up.

• After version-up, recovery processing is executed automatically.
• Part number of the recovery disc for version-up will be noticed when it is supplied.
• Updating firmware

1. Load the recovery disc that is supplied to the player and run it.
2. Firmware version of the player is automatically checked.  Appropriate message appears whenever necessary.
3. Using remote controller's cursor key, select whether version updating is to be done or not.  (Selection of Yes/No)
4. a. If Yes is selected, version updating is performed.

b. If No is selected, only recovery is performed.

5. a. When updating is finished, remove the disc according to the message appearing on the screen.

b. Remove the disc according to the message appearing on the screen.

6. Turn off the power.

If the AC power supply is shut out during version-up due to a power failure, the version-up is improperly carried out.
In such a case, replace the EEPROM and carry out the version-up again.

Be sure to take static electricity countermeasures before adjusting the optical system.  Adjust the optical systems according to
the prescribed procedure.

• Optical pickup tilt adjustment is needed after replacement of the following components.

1. Optical pickup unit
2. Disc motor
3. Traverse motor
4. Optical pickup peripheral parts (such as rail)

Adjustment is generally unnecessary after replacing other parts of the traverse unit.  However, make adjustment if there is
a noticeable degradation in picture quality.
Optical adjustments cannot be made inside the optical pickup.

• Follow the adjustment procedures described in this Manual.

• Surface precision is vital for DVD test discs.  Be sure to store and handle them carefully.

1. Do not place discs directly onto the workbench, etc., after use.
2. Handle discs carefully in order to maintain their flatness.  Place them into their case after use and store them vertically.  Store

discs in a cool place where they are not exposed to direct sunlight or air from air conditioners.

3. Accurate adjustment will not be possible if the disc is warped when placed on a surface made of glass, etc.  If this happens, use a

new test disc to make optical adjustments.

4. If adjustment is done using a warped disc, the adjustment will be incorrect and some discs will not be playable.
