EJECTING TROUBLESOME DISKS (EMERGENCY USE) D24 41 If the D24 is turned off inadvertently, or the disk loading mechanism fails, you may not be able to eject a disk in the normal way. In this case, the disk can be ejected using the supplied disk eject tool. Note that this t

21、echnique should only be used as a last resort, as frequent use may lead to malfunction. 1Turn off the D24 Power switch. 2Insert the disk eject tool into the manual eject hole, as shown below, and push gently to eject the disk. 3The disk ejects.
