Roland C-190 用户手册

 Troubleshooting

C-190 Portable Organ 

r

If you encounter problems with the C-190, please read 
the following before assuming that there is a malfunc-
tion.

■The C-190 cannot be switched on

■No sound is produced

Is the [VOLUME] slider set to the minimum position 
(page 9)? 

Are headphones connected? Disconnect them 
(page 9).

■Cannot hear the PEDAL sound

Is the [PEDAL] slider set to the minimum position 
(page 9)?

Does the indicator of one of the PEDAL tabs light?

Did you connect a MIDI cable to the PEDAL IN socket? 
In that case, the PEDAL division needs to be played 
from a PK-series pedal unit.

■Cannot select orchestral sounds

Does the [ORCHESTRA] button light? If not, press it.

■The organ sounds are not available

Does the [ORCHESTRA] indicator light? Press it so 
that its indicator goes dark. 

■Two sounds are produced when the keyboard is 

played
Did you press a MANUAL II tilt tab (whose indicator 
now lights)? Switch it off.

■The pitch of the keyboard seems incorrect

Is the [TUNE] setting correct (page 16)?

■The C-190 does not respond to your playing

Did you select the Demo mode? Leave that mode 
(page 10).

■While the ORCHESTRA indicator lights, some 

sounds are transposed one octave down when a 
PEDAL sound is selected
This is normal and intended to provide a more natu-
ral distribution of the pitches for the left and right 
sections.

■The MANUAL I sound is not available to the left 

of the split point
Did you switch on at least one MANUAL I tilt tab after 
switching off the [II÷I] tilt tab? 

■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-190. 

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-190 is connected to an external 

device
Are the connections between the C-190 and the MIDI 
sequencer or the other external device correct 
(page 23)?
