P-115  Owner’s Manual

• 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.

• 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.

• Remove the electric plug from the outlet when the instrument is not to be used for 

extended periods of time, or during electrical storms.

• Do not place the instrument in an unstable position where it might accidentally 

fall over.

• Before moving the instrument, remove all connected cables, to prevent damage 

to the cables or injury to anyone who might trip over them.

• 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 it, 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.

• 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 insert a finger or hand in any gaps on the instrument. 

• Never insert or drop paper, metallic, or other objects into the gaps on the panel or 

keyboard. This could cause physical injury to you or others, damage to the 
instrument or other property, or operational failure.

• 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 use the instrument/device or headphones 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.

Always turn the power off when the instrument is not in use. 

Even when the [

] (Standby/On) switch is in standby status (power lamp is off), electricity is still flowing to the instrument at the minimum level. 

When you are not using the instrument for a long time, make sure you unplug the power cord from the wall AC outlet.

To avoid the possibility of malfunction/ damage to the product, 
damage to data, or damage to other property, follow the notices 
below.

 Handling

• 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. When you use the instrument along with an application on your 
iPad, iPhone or iPod touch, we recommend that you set “Airplane Mode” to “ON” 
on that device in order to avoid noise caused by communication. 

• 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, damage to the internal components 
or unstable operation. (Verified operating temperature range: 5° – 40°C, or 41° – 
104°F.)

• Do not place vinyl, plastic or rubber objects on the instrument, since this might 

discolor the panel or keyboard.

 Maintenance

• When cleaning the instrument, use a soft cloth. Do not use paint thinners, 

alcohol, solvents, cleaning fluids, or chemical-impregnated wiping cloths.

 Saving data

• Some types of data (page 24) will be stored in internal memory, and maintained 

even if the power is turned off. However, the data could be lost due to malfunction 
or incorrect operation. Save important data to a computer.

 About copyrights

• Copying of the commercially available musical data including but not limited to 

MIDI data and/or audio data is strictly prohibited except for your personal use.

• This product incorporates and bundles computer programs and contents in which 

Yamaha owns copyrights or with respect to which it has license to use others' 
copyrights.  Such copyrighted materials include, without limitation, all computer 
software, style files, MIDI files, WAVE data, musical scores and sound recordings. 
Any unauthorized use of such programs and contents outside of personal use is 
not permitted under relevant laws.  Any violation of copyright has legal 
consequences.  DON’T MAKE, DISTRIBUTE OR USE ILLEGAL COPIES.

 About functions/data bundled with the instrument

• Some of the preset songs have been edited for length or arrangement, and may 

not be exactly the same as the original.

 About this manual

• The illustrations as shown in this manual are for instructional purposes only, and 

may appear somewhat different from those on your instrument.

• iPad, iPhone and iPod touch are trademarks of Apple Inc., registered in the U.S. 

and other countries.

• The company names and product names in this manual are the trademarks or 

registered trademarks of their respective companies.

 Tuning

• Unlike an acoustic piano, this instrument does not need to be tuned by an expert 

(although the pitch can be user-adjusted to match other instruments). This is 
because the pitch of digital instruments is always maintained perfectly.

Yamaha cannot be held responsible for damage caused by improper use or modifications to the instrument, or data that is lost or destroyed.
