PRECAUTIONS

PLEASE READ CAREFULLY BEFORE PROCEEDING

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

For AC adaptor

 WARNING

• This AC adaptor is designed for use with only Yamaha electronic instruments. Do 

not use for any other purpose.

• Indoor use only. Do not use in any wet environments.

 CAUTION

• When setting up, make sure that the AC outlet is easily accessible. If some trouble 

or malfunction occurs, immediately turn off the power switch of the instrument 
and disconnect the AC adaptor from the outlet. When the AC adaptor is connected 
to the AC outlet, keep in mind that electricity is flowing at the minimum level, even 
if the power switch is turned off. When you are not using the instrument for a long 
time, make sure to unplug the power cord from the wall AC outlet.

For PSR-F51

 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:

• Do not place the power cord near heat sources such as heaters or radiators. Also, 

do not excessively bend or otherwise damage the cord, or place heavy objects on 
it.

• 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 (page 11) 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.

• This instrument contains no user-serviceable parts. Do not open the instrument 

or attempt to disassemble or modify the internal components in any way. 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, place on it any containers (such as vases, bottles or glasses) 
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.

• Follow the precautions below. Failure to do so might result in explosion, fire, 

overheating or battery fluid leakage.

- Do not tamper with or disassemble batteries.

- Do not dispose of batteries in fire.

- Do not attempt to recharge batteries that are not designed to be charged.

- Keep the batteries separate from metallic objects such as necklaces, hairpins, 

coins, and keys.

- Use the specified battery type (page 11) only.

- Use new batteries, all of which are the same type, same model, and made by 

the same manufacturer.

- Always make sure all batteries are inserted in conformity with the +/- polarity 

markings.

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

time, remove the batteries from the instrument.

- When using Ni-MH batteries, follow the instructions that came with the 

batteries. Use only the specified charger device when charging.

• Keep batteries away from small children who might accidentally swallow them.

• 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.

• When one of the following problems occur, immediately turn off the power switch 

and disconnect the electric plug from the outlet. (If you are using batteries, 
remove all batteries from the instrument.) Then have the device inspected by 
Yamaha service personnel.

- The power cord or plug becomes frayed or damaged.

- It emits unusual smells or smoke.

- Some object has been dropped into the instrument.

- There is a sudden loss of sound during use of the instrument.
