Problem

ly in the display.
Vertical lines can be seen in
the screen.

The volume level of the instru-

80S/60S is too low.

Check
In the Score screen, some lyrics or
notes could extend beyond the edges
of the screen, and not be displayed.
The score display feature is particu-
larly unsuitable for the display of
difficult, complex musical works
that demand accurate notation.
If you select a part that does not con-
tain performance data, notes will not
be displayed in the score.
This is attributable to the design fun-
damentals of a liquid crystal display,
and does not indicate a malfunction.
Playing at loud volumes may cause
instruments near the AT-90S/80S/
60S to resonate. Resonance can also
occur with fluorescent light tubes,
glass doors, and other objects. In par-
ticular, this problem occurs more
easily when the bass component is
increased, and when the sound is
played at higher volumes.
When listening through head-
phones:
Here, a different cause (such as reso-
nance produced by the AT-90S/80S/
60S) would be suspect.
Could you be using a connection ca-
ble that contains a resistor?
Solution
This is not a malfunction.
This is not a malfunction.
Change the part that is displayed.
Adjusting the display's contrast can
make such lines less noticeable, so
you may want to try adjusting it.
Use the following measures to sup-
press such resonance.
Place speakers so they are 10-15 cm
from walls and other surfaces.
Reduce the volume.
Move the speakers away from any
resonating objects.
Consult your Roland dealer or near-
est Roland Service Center.
Use a connection cable that does not
contain a resistor.
