Yamaha PSR-330 - Manual (Page 3)

1
• 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 acciden-
tally 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 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,
use the provided screws only. Failure to do so could cause damage to the
internal components or result in the instrument falling over.
• 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.
■ SAVING USER DATA
• Save all data to an external device such as the Yamaha MIDI Data Filer
MDF2, in order to help prevent the loss of important data due to a malfunc-
tion or user operating error.
Yamaha cannot be held responsible for damage caused by improper use or modifi-
cations 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.
PRECAUTIONS
PLEASE 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 immediately 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 AC adaptor 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
or smoke should appear to be caused by it, immediately turn off the power
switch, disconnect the adaptor plug from the outlet, and have the instru-
ment inspected by qualified Yamaha service personnel.
• Use the specified adaptor (PA-5, PA-5B, PA-5C or an equivalent recommended
by Yamaha) only. Using the wrong adaptor can result in damage to the instru-
ment or overheating.
• Before cleaning the instrument, always remove the electric plug from the out-
let. 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:
• Do not place the AC adaptor cord near heat sources such as heaters or
radiators, 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.
• Do not connect the instrument to an electrical outlet using a multiple-con-
nector. Doing so can result in lower sound quality, or possibly cause over-
heating in the outlet.
• Unplug the AC power adaptor when not using the instrument, or during elec-
trical storms.
• Always make sure all batteries are inserted in conformity with the +/– polarity
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 to-
gether 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, 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 compo-
nents, 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 com-
ponents.
WARNING
Always follow the basic precautions listed below to avoid the possibility of serious injury or even death from electrical shock,
short-circuiting, damages, fire or other hazards. These precautions include, but are not limited to, the following:
