Troubleshooting
 
If you are encountering problems with the unit, please read the section below before assuming that there is a malfunction.
 
Case
Cause/Remedy
 
The piano 
cannot be 
switched on
 
Is the AC adaptor properly connected? 
(p. 10)
 
No sound is 
produced
 
Is the [Volume] knob set to the 
minimum position? (p. 12)
Has a plug remained connected to the 
phones jack? (p. 12)
 
Only One Tone 
Plays in Dual 
Play
 
Depending on the setting for volume 
balance, and the particular selection of 
tones you make, certain tones may be 
difficult to hear when layered. Try 
adjusting volume balance (p. 21).
 
Demo songs 
do not play
 
 
Buttons do not 
function
Keyboard 
sound does not 
change
Two sounds 
are produced 
when the 
keyboard is 
played
 
Is the keyboard in Dual Play mode? 
(p. 16)
 
The tone has 
changed in the 
Dual Play
 
If you use Dual Play with a Tone button 
for which tone number 3 or 4 is selected, 
tone number 1 will be selected for that 
Tone button (p. 15).
 
The pitch of the 
keyboard 
sounds 
incorrect
 
Is the Master Tuning setting correct? 
(p. 20)
Is the Key Transpose setting correct? 
(p. 20)
 
The recorded 
performance 
has 
disappeared
 
Any performance that has been 
recorded is deleted when the power to 
the F-50 is turned off. A performance 
cannot be restored once it’s been 
deleted.
 
Sound is 
distorted
 
Raising the volume too high may distort 
the sound. Adjust the volume level with 
the [Volume] knob (p. 12).
With certain tones, the sounds may 
seem to be distorted.
 
In the upper 
range, the 
sound changes 
abruptly 
beyond a 
certain key
 
On an acoustic piano, notes in the upper 
one and a half octaves of the keyboard 
continue to sound until they decay 
naturally, regardless of the damper 
pedal. There is a difference in the timbre 
as well. Roland pianos faithfully 
simulate such characteristics of the 
acoustic piano. On the F-50, the range 
that is unaffected by the damper pedal 
will change depending on the Key 
Transpose setting.
 
High-Pitched 
Whine is 
Produced
 
When listening through headphones: 
 
Certain piano tones that feature vibrant, 
sparking sounds contain a large high-
frequency component, which may make 
it appear that a metallic reverberation 
has been applied. This faithfully 
reproduces the characteristics of 
acoustic pianos, and does not indicate 
any malfunction. Since this 
reverberation becomes particularly 
audible when supplemented by heavy 
reverb, you may be able to diminish the 
problem by reducing the amount of 
reverb applied to the sound.
 
If you can’t hear the problem in the 
headphones: 
 
Here, a different cause (such as 
resonance produced by the F-50) would 
be suspect. Consult your Roland dealer 
or nearest Roland Service Center.
 
Bass notes 
sound wrong/
buzzing or 
vibration 
occurs
 
If you can’t hear the problem in the 
headphones: 
 
When playing at high volumes, 
resonance may occur in the piano itself 
or in objects near the piano. At times, 
other objects in the room, such as 
fluorescent lights or glass doors, could 
start vibrating. Such phenomenon 
becomes more prevalent when 
sounding the lower frequencies at high 
volume. To minimize such unwanted 
resonance, please observe the following: 
• Locate the instrument so it is 10-15 
cm away from walls.
• Reduce the volume.
• Increase the distance from the object 
that is resonating.
 
If you can hear the problem in the 
headphones: 
 
The problem may be for a different 
reason. Please contact your dealer.
