DGX-630/YPG-635 Owner’s Manual 5

• 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 use the instrument/device or headphones 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

• The panel settings and some other types of data are not retained in memory

when you turn off the power to the instrument. Save data you want to keep to the

Registration Memory (page 90.)

Saved data may be lost due to malfunction or incorrect operation. Save

important data to a USB storage device/or other external device such as a

computer (pages 99, 100, 110).

Backing up the USB storage device/external media

•To protect against data loss through media damage, we recommend that you

save your important data onto two USB storage devices/external media.

Always turn the power off when the instrument is not in use.

Even when the power switch is in the “STANDBY” position, electricity is still ﬂowing to the instrument at the minimum level. When you are not using the instrument for a long

time, make sure you unplug the AC power adaptor from the wall AC outlet.
