PSR-E323/YPT-320   Owner’s Manual

* Please keep this manual in a safe place for future reference.

• Only use the voltage specified as correct for the instrument. The required voltage 

is printed on the name plate of the instrument.

• Use the specified adaptor (PA-130 or an equivalent recommended by Yamaha) 

only. Using the wrong adaptor can result in damage to the instrument or 
overheating.

• Check the electric plug periodically and remove any dirt or dust which may have 

accumulated on it.

• 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.

• 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 any liquid such as water seeps into the instrument, turn off the power 
immediately and unplug the power cord from the AC outlet. Then have the 
instrument inspected by qualified Yamaha service personnel.

• Never insert or remove an electric plug with wet hands.

• Do not put burning items, such as candles, on the unit. 

A burning item may fall over and cause a fire.

• 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 instrument inspected by 
qualified Yamaha service personnel.

• When removing the electric plug from the instrument or an outlet, always hold the 

plug itself and not the cord.

• Unplug the AC power adaptor when not using the instrument, or during electrical 

storms.

• 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.

• 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 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.
• When the batteries run out, or if the instrument is not to be used for a long time, 

remove the batteries from the instrument to prevent possible leakage of the battery 
fluid.

• Keep batteries away from children.
• If the batteries do leak, avoid contact with the leaked fluid. If the battery fluid 

should come in contact with your eyes, mouth, or skin, wash immediately with 
water and consult a doctor. Battery fluid is corrosive and may possibly cause loss 
of sight or chemical burns.

• 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 in the vicinity of a TV, radio, stereo equipment, mobile 

phone, or other electric devices. Otherwise, the instrument, TV, or radio may 
generate noise.

• 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 setting up the product, make sure that the AC outlet you are using is easily 

accessible. If some trouble or malfunction occurs, immediately turn off the power 
switch and disconnect the plug from the outlet. Even when the power switch is 
turned off, electricity is still flowing to the product at the minimum level. When you 
are not using the product for a long time, make sure to unplug the power cord from 
the wall AC outlet.

• 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 damage to the internal 
components or result in the instrument falling over.

• 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.
