C7 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 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. 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 12). 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 18). 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 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 [MASTER VOLUME] knob (page 9). Make sure a pair of headphones or conversion adaptor is not connected to the [PHONES] jack (page 9). The Volume Limiter setting is "On". Set the Volume Limiter to "Off" (page 11). 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 18). 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. 19 YDP-105 Owner's Manual
