(dual layer), and SACD 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. However, for SACD disc, use the player with initial
data if the disc is not available.

After parts related to the servo circuit (RF amplifier, DSP, motor
driver, EEPROM (IC101) so on) are replaced, re-adjusting the servo
circuit is necessary. Select “ALL” at “DRIVE AUTO
ADJUSTMENT ” and adjust DVD-SL (single layer), CD and
DVD-DL (dual layer).

  key,  and the servo set data in

EEPROM will be initialized. Then, 1. DVD-SL disc, 2. CD disc, 3.
DVD-DL disc, and 4. SACD disc are adjusted in this order. Each
time one disc was adjusted, it is ejected. Replace it with the specified
disc following the message. Though the message to confirm whether
discs other than SACD disc are adjusted is not displayed, you can
finish the adjustment if pressing the  x  button. 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.
