Power does not turn on
 
Is the power cord connected correctly?
 
Pedal does not work, or is “stuck”
 
Is the pedal connected correctly? 
Plug the cable firmly into the pedal connector.
If you disconnect the pedal cable from the HP203 while the power is on, the 
pedal effect may remain “stuck” in the On condition.
You must power-off the HP203 before connecting or disconnecting the pedal 
cable.
If you’ve switched the function of the soft pedal or sostenuto pedal, these 
pedals will not operate as the soft pedal or sostenuto pedal.
 
Unable to read from/write to USB 
memory
 
Are you using (optional) Roland USB memory?
Reliable performance cannot be guaranteed if you use non-Roland USB 
memory products.
If you are unable to read or write USB memory successfully, change the 
External Memory setting to “Mode 1.”
 
“Buzz” is heard from external 
devices
 
Are the external devices connected to more than one AC power outlet? 
If you connect external devices, be sure to connect them to the same AC outlet.
 
Device connected to the Input 
jacks have insufficient volume
 
Could you be using a connection cable that contains a resistor?
Use a connection cable that does not contain a resistor.
 
No sound
 
No sound
 
Could the HP203’s volume or the volume of the connected equipment be 
turned down?
Could headphones be connected?
Could there be a plug inserted in a headphone jack? 
The speakers will not produce sound if headphones or plug are connected to 
the headphone jacks.
Has Local Control been set to “Off”? 
When Local Control is set to Off, no sound is produced by playing back a 
song. Set Local Control to On.
 
No sound when you play back a 
song
 
Has Local Control been set to “Off”? 
When Local Control is set to Off, no sound is produced by playing back a 
song. Set Local Control to On.
Could the song volume be set to “0”?
 
No sound from the leftmost notes 
of the keyboard
 
Is V-LINK switched on? 
When V-LINK is on, the lowest twelve notes of the keyboard are used to control 
the image, and will not produce sound.
 
No sound (when a MIDI device is 
connected)
 
Are all devices powered on?
Are the MIDI cables connected correctly?
Do the MIDI channels of the HP203 and the connected device match?
 
Not all the notes you play are 
sounded
 
The maximum simultaneous polyphony is 128 notes. If you are playing along 
with a song and making heavy use of the damper pedal, the number of notes 
the HP203 is attempting to produce may exceed the maximum polyphony, 
meaning that some of the notes will drop out.
