[User |dispiay| Description

* Mechanism position just before the LOADING

mechanism

shifts to the disc selection operation when the DCNT pin is

low. (The DCNT pin is usually high when the LOADING

mechanism is in the stop state. The mechanism position is

thus judged to have been shifted for some reason. The shifted

mechanism position may cause a failure.)

«Discrepancy has occurred between the detected disc position

and the current disc position during movement of the loading

mechanism.

(The system may incorrectly counted the

waveforms of the DCNT and DPOS terminals. If counting is

incorrect, the position of the disc No. displayed does not match

the disc position counted.)

* Mechanism position during disc loading when the DCNT pin

is low. (The DCNT pin is usually high when the LOADING

mechanism is in the stop state. The mechanism position is

thus judged to have been shifted for some reason. The shifted

mechanism position may cause a failure.)
