Appendix Troubleshooting Problem Possible Cause and Solution Power suddenly and unexpectedly turns off. This is normal and the Auto Power Off function may have been activated (page 12). If desired, disable the Auto Power Off function. The instrument does not turn on. Securely insert the adaptor plugs into the socket on this instrument and into a proper AC outlet (page 11). 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 this instrument. Turn off the mobile phone, or move it further away from this instrument. Noise is heard from the instrument's speakers or headphones when using the instrument with the application on iPhone/iPad. When you use the instrument along with the application on your iPhone/ iPad, we recommend that you set "Airplane Mode" to "ON" on your iPhone/ iPad 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 13). The overall volume is low, or no sound is heard. Make sure a pair of headphones is not connected to the headphones jack (page 12). Make sure that Local Control is On. For details, refer to the "MIDI Reference" (page 8). Pedals do not function. 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 (page 30). The damper pedal does not function as expected. The damper pedal was pressed when the power was turned on. This is not a malfunction; release the pedal and press it again to reset the function. 28 CLP-525 Owner's Manual
