The Test Mode allows you to make diagnosis and adjustment easily
using the remote commander and monitor TV. The instructions,
diagnostic results, etc. are given on the on-screen display (OSD).
After parts related to the servo circuit (RF amplifier (IC001), DSP
(IC509), motor driver (IC501), EEPROM (IC204) so on) are
replaced, re-adjusting the servo circuit is necessary. Select “ALL”
at  “1. DRIVE AUTO ADJUSTMENT” (Refer to page 16 inTEST
MODE) and adjust DVD-SL (single layer), CD and DVD-DL
(dual layer).

Use the following test disc on test mode.

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.

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 below, then adjusted values will be written to the
