To initialize the backup parameters: While holding down the C7 key (highest key), turn the power on to initialize the backup data to the factory initial settings. Highest key NOTICE • Never turn off the power while the initialization is being executed. NOTE • If this instrument somehow malfunctions or fails to operate properly, try executing the initialization. Troubleshooting 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. When using a DAW (Digital Audio Workstation) with an instrument, there is a loud noise or abnormal sound. 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 9). This is normal. This occurs due to the Auto Power Off function (page 9). 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. When you use the instrument along with the application on your smart device, we recommend that you set "Airplane Mode" to "ON" on your smart device in order to avoid noise caused by communication. The Master Volume is set too low. Set it to an appropriate level using the [VOLUME] slider (page 8). Make sure a pair of headphones or conversion adaptor is not connected to the [PHONES] jack (page 8). The pedal cable/plug may not be properly connected. Turn off the power and make sure to securely insert the pedal plug into the [SUSTAIN] jack or [PEDAL UNIT] jack (page 9, 15). 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. Depending on the settings of the computer or the application software, a loud sound may occur. Set the Audio Loop Back function to off (page 11). P-145, P-143 Owner's Manual 13
