Troubleshooting.

Problem.	
The YDP-123 does not turn on.	
Possible Cause and Solution.
The YDP-123 has not been plugged in properly. Securely insert the female plug into the socket on the YDP-123, and the male plug into a proper AC outlet (page 11).

Problem.
A click or pop is heard when the power is turned on or off.	
Possible Cause and Solution.
This is normal when electrical current is being applied to the instrument.

Problem.
Noise from the speakers or headphones is audible.
Possible Cause and Solution.
The noise may be due to interference caused by the use of a mobile phone in close proximity to the YDP-123. Turn off the mobile phone, or move it further away from the YDP-123.

Problem.
The overall volume is low, or no sound is heard.	
Possible Cause and Solution.
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.
Make sure that Local Control (page 26) is ON.

Problem.
The damper pedal has no effect, or the sound continuously sustains even when the damper pedal is not pressed.	
Possible Cause and Solution.
The pedal cord may not be properly connected. Make sure to securely insert the pedal cord into the [PEDAL] jack (page 30).
