• Do not attempt to recharge batteries that are not intended to be charged.
• If the instrument is not to be in use for a long time, remove the batteries from it, in order to prevent possible fluid
leakage from the battery.
• Keep batteries away from children.
• 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.
• Do not expose the instrument to excessive dust or vibrations, or extreme cold or heat (such as in direct sunlight,
near a heater, or in a car during the day) to prevent the possibility of panel disfiguration or damage to the internal
components.
• Do not use the instrument near other electrical products such as televisions, radios, or speakers, since this might
cause interference which can affect proper operation of the other products.
• Do not place the instrument in an unstable position where it might accidentally fall over.
• Before moving the instrument, remove all connected adaptor and other cables.
• When cleaning the instrument, use a soft, dry cloth. Do not use paint thinners, solvents, cleaning fluids, or
chemical-impregnated wiping cloths. Also, 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.
DATA BACK-UP AND STORAGE
■ Yamaha recommends that you regularly save your music data using an external MIDI data storage device (such as
the Yamaha MDF3 MIDI Data Filer), and storing the floppy disks in a safe, cool, dry place. YAMAHA CANNOT BE
HELD RESPONSIBLE FOR THE ACCIDENTAL LOSS OF IMPORTANT MUSIC DATA! Regarding the User memory,
as long as fresh batteries are inserted in (or an AC power adaptor is connected to) the RY9, the User pattern, song
and drum kit data will be retained, even when the power is turned off. It will also be retained long enough to
exchange an old set of batteries for a new set. If you have important data in the RY9 which you don’t want to lose,
please take care to keep fresh batteries inserted in (or keep an AC power adaptor connected to) the RY9, and to
regularly save it to an external MIDI data storage device.
Yamaha cannot be held responsible for damage caused by improper use or modifications to the instrument, or
data that is lost or destroyed.
Always turn the power off when the instrument is not in use.
Make sure to discard used batteries according to local regulations.
