ENGLISH Troubleshooting Troubleshooting Problem Possible Cause and Solution The P-140 does not turn on. The P-140 has not been plugged in properly. Securely insert the female plug into the socket on the P-140, and the male plug into a proper AC outlet (page 12). A click or pop is heard when the power is turned on or off. This is normal when electrical current is being applied to the instrument. Noise is heard from the speakers or headphones. The noise may be due to interference caused by the use of a mobile phone in close proximity to the P-140. Turn off the mobile phone, or use it further away from the P140. The overall volume is low, or no sound is heard. • 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 13). • Make sure that Local Control (page 44) is ON. The sustain pedal has no effect. The pedal cable/plug may not be properly connected. Make sure to securely insert the pedal plug into the proper jack (page 47). The foot pedal seems to produce the opposite effect. For example, pressing the foot pedal cuts off the sound and releasing it sustains the sounds. The type of the foot pedal is reversed. If this happens, use F5.6 or F5.7 to correct the pedal type (pages 37, 43). If you press the [VARIATION] button during performance, Sound is cut off. This is normal, and is no cause for concern.

A click or pop is heard when the power is
turned on or off.
This is normal when electrical current is being applied to the instrument.
Noise is heard from the speakers or head-
phones.
The noise may be due to interference caused by the use of a mobile phone in close
proximity to the P-140. Turn off the mobile phone, or use it further away from the P-
140.

heard.
•

The foot pedal seems to produce the oppo-
site effect. For example, pressing the foot
pedal cuts off the sound and releasing it sus-
tains the sounds.
The type of the foot pedal is reversed.
If this happens, use F5.6 or F5.7 to correct the pedal type (pages 37, 43).
