Backup data Metronome Volume, Metronome Beat, Touch Sensitivity, Tuning, Auto Power Off, Operation Confirmation Sound on/off To initialize the backup data: While holding down the C7 key (right-most key), turn the power on to initialize the backup data to the factory initial settings. C7 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. Appendix Troubleshooting Problem Power suddenly and unexpectedly turns off. The instrument does not turn on. A click or pop is heard when the power is turned on or off. Noise is heard from the speakers or headphones. Noise is heard from the instrument's speakers or headphones when using the instrument with the application on iPhone/iPad. The overall volume is low, or no sound is heard. Pedals do not function. The damper pedal does not function as expected. Possible Cause and Solution This is normal and the Auto Power Off function may have been activated (page 13). If desired, disable the Auto Power Off function. The plugs are not properly connected. Make sure that the DC plug is securely inserted into the DC IN jack on the instrument, and that the AC plug is securely inserted to the AC outlet (page 12). This is normal when electrical current is being applied to the instrument. 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 iPhone/iPad, we recommend that you set "Airplane Mode" to "ON" on your iPhone/iPad in order to avoid noise caused by communication. While Bluetooth is connected, setting "Airplane Mode" to "ON" disconnects Bluetooth; however, the connection can be restored by reconnecting again. The Master Volume is set too low. Set it to an appropriate level using the [MASTER VOLUME] knob (page 12). Make sure a pair of headphones or conversion adaptor is not connected to the [PHONES] jack (page 13). 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 23). 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. 21 YDP-103 Owner's Manual
