• Before connecting the instrument to other electronic components, turn off the 
power for all components. Before turning the power on or off for all components, 
set all volume levels to minimum. Also, be sure to set the volumes of all 
components at their minimum levels and gradually raise the volume controls 
while playing the instrument to set the desired listening level.
• When cleaning the instrument, use a soft, dry cloth. Do not use paint thinners, 
solvents, cleaning fluids, or chemical-impregnated wiping cloths. 
• Do not insert a finger or hand in any gaps on the instrument. 
• Never insert or drop paper, metallic, or other objects into the gaps on the panel 
or keyboard. If this happens, turn off the power immediately and unplug the 
power cord from the AC outlet. Then have the instrument inspected by qualified 
Yamaha service personnel. 
• Do not place vinyl, plastic or rubber objects on the instrument, since this might 
discolor the panel or keyboard.
• Do not rest your weight on, or place heavy objects on the instrument, and do not 
use excessive force on the buttons, switches or connectors.
• Do not operate the instrument for a long period of time at a high or 
uncomfortable volume level, since this can cause permanent hearing loss. If you 
experience any hearing loss or ringing in the ears, consult a physician.
Saving and backing up your data
• RAM data (see page 65) is lost when you turn off the power to the instrument. 
Save the data to the User, Floppy Disk or optional Hard Disk drives. Saved data 
may be lost due to malfunction or incorrect operation. Save important data to a 
floppy disk or optional hard disk.
• When you change settings in a display page and then exit from that page, 
System Setup data (listed in the Parameter Chart of the separate Data List 
booklet) is automatically stored. However, this edited data is lost if you turn off 
the power without properly exiting from the relevant display.
Backing up the floppy disk
• To protect against data loss through media damage, we recommend that you 
save your important data onto two floppy disks.
Always turn the power off when the instrument is not in use.

Caution for data operations
Make sure NEVER to turn the TYROS’ power off during any kind of data operation involving the USER/FD/HD drives — such as saving, deleting, or copying/pasting — 
until the operation is completely finished. (Make sure to wait until the alert message shown below disappears.) Turning the power off during the operation results in the 
loss of the data being saved or pasted to the respective drive.
Keeping the power on during such operations is particularly important in regard to the USER drive. Turning off the power while performing a save/delete/paste operation 
with the USER drive may result in loss of ALL data on the USER drive (upon the next power on) — and not just the data in question. In other words, if you are performing 
a save/delete/paste operation on only the song data of the USER drive and you turn off the power before the operation is completed, you risk losing ALL your USER drive 
data — including all voices, styles, Multi Pad banks and Registration Memory presets you’ve saved to the USER drive.
This caution also applies to creating a new folder on the USER drive or using the factory reset operation (page 159).
Yamaha cannot be held responsible for damage caused by improper use or modifications to the instrument, or data that is lost or 
destroyed.
