Possible Cause and Solution
This is normal and the Auto Power Off function may have been activated
(page 14). If desired, disable the Auto Power Off function.
The plugs are not properly connected. Make sure that the DC plug is
securely inserted into the DC IN jack on the instrument, and that the AC
plug is securely inserted to the AC outlet (page 13).
This is normal when electrical current is being applied to the instrument.
The noise may be due to interference caused by the use of a mobile phone
in close proximity to this instrument. Turn off the mobile phone, or move it
further away from this instrument.
When you use the instrument along with the application on your smart
device, we recommend that you set "Airplane Mode" to "ON" on your smart
device in order to avoid noise caused by communication.
The Master Volume is set too low. Set it to an appropriate level using the
[MASTER VOLUME] knob (page 10).
Make sure a pair of headphones or conversion adaptor is not connected to
the [PHONES] jack (page 15).
The Speaker setting is "Off." Set the Speaker to "Normal" or "On" (page 15).
The Volume Limiter setting is "On".Set the Volume Limiter to "Off" (page 14).
Make sure that Local Control is On. For details, refer to the "MIDI
Reference" (page 8).
The pedal cord may not be securely connected to the [TO PEDAL] jack. Be
sure to insert the pedal cord all the way until the metal part of the cord plug
disappears from view (pages 36, 39).
This is no problem.
Yamaha develops the Piano Voices so that the original piano sound is
reproduced as faithfully as possible. This is why you may hear overtones
emphasized in a certain key range, or you may feel that the sound pitch or
quality is different from another key range.
This is no problem.
The keyboard mechanism of this product is designed to simulate the actual
noises of an acoustic piano. Such noises are produced even if you play an
acoustic piano.
This is no problem.
It is because the [+R] and [−L] lamps may flash when the internal
processing of this product is taking a long time. Note that no operations are
available while these are flashing.
