PRECAUTIONSPLEASE READ CAREFULLY BEFORE PROCEEDING
* Please keep these precautions in a safe place for future reference.
• Do not open the instrument or attempt to disassemble the internal parts
or modify them in any way. The instrument contains no user-serviceable
parts. If it should appear to be malfunctioning, discontinue use immedi-
ately and have it inspected by qualified Yamaha service personnel.
• Do not expose the instrument to rain, use it near water or in damp or wet
conditions, or place containers on it containing liquids which might spill
into any openings.
• If the power cord or plug becomes frayed or damaged, or if there is a
sudden loss of sound during use of the instrument, or if any unusual smells
• Do not place the power cord near heat sources such as heaters or radia-
tors, and do not excessively bend or otherwise damage the cord, place
heavy objects on it, or place it in a position where anyone could walk on,
trip over, or roll anything over it.
• When removing the electric plug from the instrument or an outlet, always
hold the plug itself and not the cord. Pulling by the cord can damage it.
• Do not connect the instrument to an electrical outlet using a multiple-
connector. Doing so can result in lower sound quality, or possibly cause
overheating in the outlet.
• Remove the electric plug from the outlet when the instrument is not to be
used for a long time, or during electrical storms.
• 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.
• 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 televi-
sions, 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 acci-
dentally fall over.
• Before moving the instrument, remove all connected 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 or plastic 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.
• Use only the stand specified for the instrument. When attaching the stand
or rack, use the provided screws only. Failure to do so could cause dam-
age to the internal components or result in the instrument falling over.
• Do not place objects in front of the instrument’s air vents on the top and
rear panels, since this may prevent adequate ventilation of the internal
components, and possibly result in the instrument overheating.
Also, be careful to place the instrument on a flat, level surface to prevent
blockage of the air vents on the bottom panel.
• Do not operate the instrument for a long period of time at a high or uncom-
fortable volume level, since this can cause permanent hearing loss. If you
experience any hearing loss or ringing in the ears, consult a physician.
■REPLACING THE BACKUP BATTERY
The PSR-8000 requires four 1.5 V C size (LR14) batteries for memory backup
power. If no backup batteries are installed, the memory contents will be lost
when the instrument is unplugged from the AC mains supply. Please use
or smoke should appear to be caused by it, immediately turn off the power
switch, disconnect the electric plug from the outlet, and have the instru-
ment inspected by qualified Yamaha service personnel.
• Only use the voltage specified as correct for the instrument. The required
voltage is printed on the name plate of the instrument.
• Before cleaning the instrument, always remove the electric plug from the
outlet. Never insert or remove an electric plug with wet hands.
• Check the electric plug periodically and remove any dirt or dust which
may have accumulated on it.
CAUTION
Always follow the basic precautions listed below to avoid the possibility of physical injury to you or others, or damage to the
instrument or other property. These precautions include, but are not limited to, the following:
alkaline batteries.
1.Before changing the battery be sure to save any important data to disk
by using the SAVE TO DISK function described on page 141.
2.Turn the PSR-8000 power OFF and unplug the power cord from both the
AC wall socket and the instrument’s rear panel. Turn the instrument up-
side down and rest it on a blanket or other soft surface.
3.Open Battery Compartment Cover
Open the battery compartment cover — located on the instrument’s
bottom panel — by pressing on the two latches on the cover and pulling
outward, as shown in the illustration.
4.Remove the old batteries (if installed).
Remove the old batteries and wait at least one minute to ensure that all
data is fully cleared.
5.Insert Batteries
Insert the four batteries, being careful to follow the polarity markings on
the bottom panel.
6.Replace Cover
Replace the compartment cover, making sure that it locks firmly in place.
• Always make sure all batteries are inserted in conformity with the +/– polar-
ity markings. Failure to do so might result in overheating, fire, or battery fluid
leakage.
• Always replace all batteries at the same time. Do not use new batteries
together with old ones. Also, do not mix battery types, such as alkaline
batteries with manganese batteries, or batteries from different makers, or
different types of batteries from the same maker, since this can cause
overheating, fire, or battery fluid leakage.
• Do not dispose of batteries in fire.
• 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 (after saving any important data to disk), in order to prevent pos-
sible fluid leakage from the battery.
• Keep batteries away from children.
■SAVING USER DATA
• Always save data to a floppy disk frequently, in order to help prevent the
loss of important data due to a malfunction or user operating error.
Yamaha cannot be held responsible for damage caused by improper use or modi-
fications 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.
