Why is the volume low or no sound heard on my Yamaha Musical Instrument?
If the overall volume is low or no sound is heard, it might be due to several reasons. First, check the [MASTER VOLUME] slider and set it to an appropriate level. Also, ensure that headphones are not connected to the headphones jack. Finally, verify that Local Control is ON; for details, refer to 'MIDI Reference' on the website.
What to do if I hear noise from the speakers of my Yamaha P-105?
If you hear noise from the speakers or headphones, it may be due to interference caused by a mobile phone close to the instrument. Try turning off the mobile phone or moving it further away from the instrument.
How to fix a Yamaha P-105 that does not turn on?
If the instrument does not turn on, ensure that the female plug is securely inserted into the jack on the instrument and the male plug is properly inserted into an AC outlet.
What to do if the pedal has no effect on my Yamaha Musical Instrument?
If the pedal has no effect, the pedal cable/plug may not be properly connected. Make sure to securely insert the pedal plug into the [SUSTAIN] or [PEDAL UNIT] jack.
Why does the footswitch produce the opposite effect on my Yamaha Musical Instrument?
If the footswitch seems to produce the opposite effect (e.g., pressing cuts off the sound), it's likely that the polarity of the footswitch is reversed because the footswitch was pressed when the power was turned on. To reset the function, turn off the power and turn it on again, making sure not to press the footswitch during power-up.
Why does my Yamaha P-105 automatically turn off?
This is normal. This occurs due to the Auto Power Off function.
