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)
Are the headphones connected? (p. 12)
Has a plug remained connected to the
phones jack? (p. 12)
Is Local On/Off set to “Off”? (p. 24)
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
Is Panel Lock on? (p. 19)
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.
