Yamaha P-70 Owner's Manual - Page 24

Troubleshooting Troubleshooting Problem The P-70 does not turn on. Noise is heard from the speakers or headphones. The overall volume is low, or no sound is heard. The sustain pedal has no effect. Possible Cause and Solution The P-70 has not been plugged in properly. Securely insert the female plug into the socket on the P-70, and the male plug into a proper AC outlet (page 11). The noise may be due to interference caused by the use of a mobile phone in close proximity to the P-70. Turn off the mobile phone, or use it further away from the P-70. • The Master Volume is set too low; set it to an appropriate level using the [MASTER VOLUME] control. • Make sure a pair of headphones is not connected to the headphones jack (page 12). • Make sure that Local Control (page 22) is ON. The pedal cable/plug may not be properly connected. Make sure to securely insert the pedal plug into the proper jack (page 12).
