If the panel door cannot be opened, the time-out error is triggered
and the measurement is also stopped at this stage. Note that the
tray can push the door forcibly as the software judges the door as
it is in the OPEN state, if the door open/close detector switches
(S1022 and S1023 on the DOOR SW board) have abnormality.

Measurement of table rotation hours, tray open/close hours and
panel door open close hours can be executed together with CDM59.

[         AMS        ]

 key to eject the tray. Place a disc in the DISC1 of the

table. (Be sure to place a disc in DISC1. If a disc is placed in
any locations other than DISC1, the correct measurement can-
not be executed. Therefore, be sure to place a disc in DISC by
using the [DISC SKIP] key.)

to the normal test mode. If any other tests are desired, turn
off the main power once and then back on again to enter
