Yamaha P-35 Owner's Manual - Page 16

Troubleshooting Appendix Problem The instrument does not turn on. The instrument is automatically turned off even if no operation is done. Noise is heard from the speakers or headphones. The overall volume is low, or no sound is heard. The pedal has no effect. The footswitch (for sustain) seems to produce the opposite effect. For example, pressing the footswitch cuts off the sound and releasing it sustains the sounds. Possible Cause and Solution The instrument has not been plugged in properly. Securely insert the female plug into the jack on the instrument, and the male plug into a proper AC outlet (page 7). This is normal. This occurs due to the Auto Power Off function (page 14). The noise may be due to interference caused by the use of a mobile phone in close proximity to the instrument. Turn off the mobile phone, or use it further away from the instrument. The Master Volume is set too low; set it to an appropriate level using the [MASTER VOLUME] slider (page 7). Make sure a pair of headphones is not connected to the headphones jack (page 7). The pedal cable/plug may not be properly connected. Make sure to securely insert the pedal plug into the [SUSTAIN] jack (page 7). The polarity of the footswitch is reversed because the footswitch was pressed when the power was turned on. Turn off the power and turn it on again to reset the function. Make sure to not press the footswitch when turning the power on. Specifications Dimensions (W x D X H) • 1,326 x 295 x 154 mm (52-3/16" x 11-5/8" x 6-1/16") Weight • 11.5 kg (25 lbs. 6 oz.)
