components, set all volume levels to minimum. Also, be sure to set the v\
olumes 
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.
• During extreme changes in temperature or humidity, condensation may occur 
and water may collect on the surface of the instrument. If water is left\

Introd uction 
Thank you for purchasing the Yamaha Digital Piano! 
We  recommend that you read this manual carefully so that you can 
fully take advantage of the advanced and convenient functions. We  also recommend that you keep this manual in a safe and 
handy place for future reference. 
M ain Features 
Graded Hammer Effect Keyboard  
Thanks to our experience as the world’s leading manufacturer of acoustic pianos, we’ve developed a keyboard with 
action that’s virtually indistinguishable from the real thing. Just  as on a traditional acoustic piano, the keys of the lower 
notes have a heavier touch, while the higher ones are more responsive to lighter playing. The keyboard’s sensitivity can 
ev en be adjusted to match your playing style.  
A WM Dynamic Stereo Sampling  
This digital piano offers a rich and versatile range of sounds, which are created using Yamaha’s proprietary sampling 
to ne-generation system, “AWM Dynamic Stereo Sampling.”
A WM (Advanced Wave Memory) is a sampling system that creates sounds close to those of an acoustic instrument by 
digitally recording the sounds of an instrument and applying high-quality digital filtering technology to the recorded 
audio samples.
The sound waveform created by an acoustic piano differs depending on the player’s strength of touch, from pianissimo 
to  fortissimo.
A WM Dynamic Stereo Sampling can create extremely dynamic nuances by recording samples at various playing 
strengths. The greater the number of samples used, the greater the resulting expressiveness of the instrument.
The piano voice “Grand Piano 1” features a totally new sample recorded from a full-size concert grand piano. Each 
note in the sample has been adjusted meticulously so that the digital piano will play only the very best piano sounds.
The piano voices are well-separated sounds featuring a fast attack and a satisfying response.
The “Grand Piano 1” voice features multiple wave samples for different velocities (Dynamic Sampling). That is, differ-
ent samples are used depending on how fast or strong the player strikes the keys. Therefore, this voice expresses 
detailed dynamics and sounds much closer to those of a true acoustic piano.
The instrument creates a rich, luxurious sound using “Sustain Sampling,” which is a sample of the soundboard and the 
r esonance of the strings when the damper pedal is pressed. The instrument also features “Key-off Sampling,” which is a 
sample of the very delicate noises that are caused when keys are released.
