When replacing the DVD board, since the adjustment value is not
set up correctly, “Drive Auto Adjustment” can’t be performed.
In this case, initialize Memory in the following procedures.

Procedure:
1. Starting test mode. (See page 19)
2. Press the [2] key of the remote commander, and set the “DRIVE

MANUAL OPERATION”. (See page 21)

3. Press the [6]  key of the remote commander, and set the “6.

Memory Check”. (See page 23)

4. Press the [CLEAR] key of the remote commander, and initialize

Memory.

After parts related to the servo circuit (RF amplifier (IC001), DSP
(IC401), motor driver (IC501), EEPROM (IC302) so on) are re-
placed, re-adjusting the servo circuit is necessary. Select “ALL” at
“1. DRIVE AUTO ADJUSTMENT” (Refer to page 20 in TEST
MODE) and adjust DVD-SL (single layer), CD and DVD-DL (dual
layer).
