Taking Care of Your PortaTone q Internal memory data can be corrupted due to incorrect operation. Be sure to "save" important data to a floppy disk frequently so you have a backup to revert to if something happens to damage the data in memory. Also note that magnetic fields can damage data on the disk, so it is advisable to make a second back-up copy of disks that contain very important data, and keep backup disks in a safe place away from stray magnetic fields (i.e. away from speakers, appliances containing motors, etc.). s Service and Modification q The PSR-4000 contains no user serviceable parts. Opening it or tampering with it in anyway can lead to irreparable damage and possibly electric shock. Refer all servicing to qualified YAMAHA personnel.

Ask your Yamaha dealer about the available of head-cleaning disks. s Disk Insertion & Removal q To insert a floppy disk in the disk drive, hold the disk with the label side facing up and the sliding shutter facing the disk drive door, then insert carefully until the disk clicks into place. q To remove a floppy disk from the disk drive, make sure the "DISK IN USE" light is not lit and press the disk eject button firmly as far as it will go and then, when the disk is full ejected, remove it by hand. If the eject button is only partially pressed or pressed too quickly the eject mechanism may not function properly, leaving the disk stuck halfway. Do not attempt to remove the disk forcefully if this happens, since excess force can damage the disk and/or the drive mechanism. Try either pressing the eject button carefully again, or push the disk all the way back into the drive and repeat the eject procedure. s Floppy Disk Handling & Storage The actual recording medium inside a floppy disk has a fine coating of magnetic particles in which the data is "stored".

Taking Care of Your PortaTone
●
Internal memory data can be corrupted due to incor-
rect operation. Be sure to “save” important data to a

if something happens to damage the data in memory.
Also note that magnetic fields can damage data on the

of disks that contain very important data, and keep
backup disks in a safe place away from stray magnetic
fields (i.e. away from speakers, appliances containing
motors, etc.).
■
Service and Modification
●
The PSR-4000 contains no user serviceable parts.
Opening it or tampering with it in anyway can lead to
irreparable damage and possibly electric shock. Refer
all servicing to qualified YAMAHA personnel.
■
Type of Disk
Use only 3.5-inch 2DD or 2HD floppy disks.
■
Disk Insertion & Removal
●
To insert a floppy disk in the disk drive, hold the disk
with the label side facing up and the sliding shutter
facing the disk drive door, then insert carefully until the
disk clicks into place.
ing Disk to clean the head about once a month. Ask your
Yamaha dealer about the available of head-cleaning
disks.
■
Floppy Disk Handling & Storage
The actual recording medium inside a floppy disk has a
fine coating of magnetic particles in which the data is
“stored”. To protect this coating as well as the disk drive’s
delicate read-write head, please observe the following:
●
Always keep floppy disks in their case when they are
not in use. Never place heavy objects on a disk or bend
the disk in any way. Also keep disks away from liquids
and dust.
●
Never open the disk’s shutter and touch the exposed
surface of the disk.
●
Keep floppy disks away from strong magnetic fields
such as those produced by television sets, speakers,
motors, etc.
●
Never leave floppy disks in areas exposed to strong
direct sunlight, excessively high or low temperature, or
high humidity.
●
Never use a floppy disk with a deformed shutter or
housing.
●
Do not attach anything other than the provided labels
to a floppy disk. Also make sure that labels are at-
tached in the proper location.
■
Protecting Your data
●
To prevent accidental erasure of important data you
have saved to floppy disk, be sure to slide the disk’s
write-protect tab to the “write protect” position (the tab
window should be open). When this is done the disk
cannot be written to.
●
Make regular backup copies of important data to a
separate floppy disk, and keep your backup disks in a
separate, safe place.
●
To ensure the safety of your data (and of the disk drive
itself) always use floppy disks from a well-known,
reliable manufacturer. “No-brand” disks can cause
trouble.
●
To remove a floppy disk from the disk drive, make sure
the “DISK IN USE” light is not lit and press the disk
eject button firmly as far as it will go and then, when the
disk is full ejected, remove it by hand.
If the eject button is only partially pressed or pressed
too quickly the eject mechanism may not function
properly, leaving the disk stuck halfway. Do not attempt
to remove the disk forcefully if this happens, since
excess force can damage the disk and/or the drive
mechanism. Try either pressing the eject button care-
fully again, or push the disk all the way back into the
drive and repeat the eject procedure.
●
Never attempt to remove a floppy disk during a record
or playback operation!! This can corrupt the data on the
disk, and actually damage the disk drive!
●
Be sure to remove the floppy disk from the disk drive
before turning off the power. A floppy disk left in the
drive for extended periods can easily pick up dust and
dirt that can cause data read/write errors.

Clean the Read/Write Head Regularly
This instrument employs a precision magnetic read/write
head which, after an extended period of use, will pick up
a layer of magnetic particles from the disks used that will
eventually cause read and write errors. To maintain
