gardless of whether a disc is in the unit or not.
Panel full OPEN/CLOSE is conducted with a short-push.
(Protection time : 3 seconds)
As far as this item is concerned, eject will be achieved by 1
second long-push on the EJECT key.
Clearing Backup/Installer memory and CD mecha-
nism error log information (E2PROM data clear)
1. While pressing [Q] and [ATT] keys simultaneously, reset to
restart. This will initiate the initializing processes of backup/
installer memory and CD mechanism error log information.
2. When the initialization process is completed, the following
displays will be made.
Normal completion : "CD_O : AU_O_"
Abnormal completion1 : "CD_O : AU_X_" --- backup/in-
staller memory, initialization NG
Abnormal completion2 : "CD_X : AU_O_" --- CD mecha-
nism error log information, initialization NG
Abnormal completion3 : "CD_X : AU_X_" --- All initializa-
tion processes NG
3. While in this mode, even after an elapse of a pre-set time,
no backup memory items will be written to the E2PROM.
4. This mode is released by resetting. (What was on the last
screen will not be retained.)
Clearing DC error detection information (E2PROM
data clear)
1. While simultaneously pressing down on [3] and [6] keys,
reset the unit to enter the DC error display mode.
2. During STANDBY sourcing, the current DC error conditions
will be displayed.
When error detected : "DC_ERR__"
When error not detected : "DC_OK___"
3. While the error conditions are being displayed, short-press
[AUTO] / [TI] keys to clear the detection information.
