Attach the hard disk unit to the hard disk cover using the
four silver screws removed from the hard disk cover in
step X.
Depending on the type of hard disk drive you plan to
install, select holes q or holes w to attach the hard disk
drive.
* Holes q are used in this illustration.
• Be careful not to drop any screws inside the instrument during
installation (this can be prevented by keeping the hard disk unit
and cover away from the instrument while attaching). If this does
happen, be sure to remove the screw(s) from inside the unit before
turning the power on. Loose screws inside the instrument can
cause improper operation or serious damage. If you are unable to
retrieve a dropped screw, consult your Yamaha dealer for advice.

Replace the hard disk cover, and attach with the four black
screws removed in step C. Install the backup batteries,
set the PSR-8000 right-side up, and connect the power
cord to the rear-panel AC INLET jack and an AC outlet.
M
Check that the installed hard disk is functioning properly.
Turn on the power, go to the DISK display, and execute the
FORMAT HARD DISK function. If the format is com-
pleted with no trouble, the hard disk is OK.
