Manually Opening the Transport Drive Draw:
Sometimes it may be necessary to open the transports drive drawer manually to recover
a disk if the unit cannot be powered up or is not functioning properly. You will need a
thin piece of shim stock (0.010”) or a small paper clip will work to perform this operation.
1. Make sure the power switch on the rear panel is off and AC line is disconnected.
2. Insert the tool into the location shown in the photo below and give it a push. It
can take a knack to do this so it may take more than one try.
3. The drawer will slide out roughly to the position shown in the lower photo.
4. Gently pull the drawer out to recover the disk. Push the drawer in when done.
