7.1 Troubleshooting

If you are encountering problems with the C-180,
please read the section below before assuming that
there is a malfunction.
The C-180 cannot be switched on
Is the adapter connected properly (see page 7)?
No sound is produced
Is the [VOLUME] slider set to the minimum position
(see page 7)?
Are headphones connected (see page 7)? Disconnect
them.
Cannot hear the BASS sound
Is the [BASS] slider set to the minimum position
(see page 7)?
Does the indicator of one of the two BASS tabs light?
Cannot select orchestral sounds
Does the ORCHESTRA indicator light? Press the
[ORCHESTRA] button to make its indicator light.
The organ sounds are not available
Does the ORCHESTRA indicator light? Press the
[ORCHESTRA] button to make its indicator go dark.
Two sounds are produced when the keyboard is
played
Have you layered two Tones (see page 13)?
The pitch of the keyboard sounds incorrect
Is the [PITCH] setting correct (see page 11)?
Is the Transpose setting correct (see page 12)?
Is the temperament setting correct (see page 11)?
The C-180 does not respond to your playing
Does the DEMO indicator light? Press its button to
make it go dark (see page 8).
The recorded performances have been deleted
This happens if you wait longer than two weeks
before switching the C-180 on again.
In Orchestra mode, some sounds are transposed
one octave down when a BASS sound is selected
This is normal and intended to provide a more natur-
al distribution of the pitches for the left and right sec-
tions.
The Manual sound is not available to the left of
the split point
In Organ mode: did you select the split bass mode
(see page 10)? Switch it off. In Orchestra mode, this is
normal whenever you select a BASS sound.
Bass notes sound wrong/buzzing or vibration
occurs
If you don't hear the problem in the headphones:
When playing at high volumes, resonance may occur
in the instrument itself, or in objects near the C-180.
At times, other objects in the room, such as fluores-
cent lights or glass doors, could start vibrating. To
minimize such unwanted resonance, please observe
the following:
• Locate the instrument at least 10~15 cm away from
the walls.
• Reduce the volume.
• Increase the distance from the object that is resonat-
ing.
If you can hear the problem in the headphones, there
may be another reason. Please contact your dealer.
When the C-180 is connected to an exter-
nal device
Are the connections between the C-180 and the MIDI
sequencer or the other external device correct (see
page 17)?
