Normally, [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 [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
judgment 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.

Press the [1] key on the remote commander and insert a DVD single
layer disc following the message. Then the adjustment will be made
through the steps, then adjusted values will be written to the
EEPROM.
