Normally, 

[10/0]

 is selected to adjust DVD (single layer), CD and

DVD (dual layer) in this order. But, individual items can be adjusted
for the case where adjustment is suspended due to an error. In this
mode, the adjustment can be made easily through the operation
following the message displayed on the screen.
The disc used for adjustment must be the one specified for
adjustment.

Press the 

[10/0]

 key on the remote commander, and the servo set

data in EEPROM will be initialized. Then, 1. DVD-SL disc, 2. CD
disc and 3. DVD-DL disc are adjusted in this order.
Each time one disc was adjusted, it is ejected. Replace it with the
specified disc following the message. You can finish the adjustment
by pressing the 

[RETURN]

 button on the remote commander.

During adjustment of each disc, the measurement for disc type judg-
ment is made. As automatic adjustment does not judge the disc
type unlike conventional models, take care not to insert wrong type
discs. Also, do not give a shock during adjustment.

Test disc: TDV-520CSO (DVD-SL) (Part No. J-2501-236-A)
