Cause/Remedy
Is the power cord connected and plugged in
correctly? (p. 18)
Is the panel locked? (p. 157)
Turn the power off, then back on.
The KR-7/5 uses a liquid-crystal screen, so
text may not be displayed when the ambient
temperature is below freezing.
These occur due to the nature of a liquid crys-
tal display, and do not indicate a malfunction.
They can be minimized by adjusting the
brightness of the screen. (p. 22)
The positioning of the touch screen may be-
come displaced if some time has passed since
it was last used. Take a look at "Calibrating
the Touch Screen (Touch Screen)" (p. 156) to
correct the positioning.
Adjust the adjuster underneath the pedal so
that the pedal presses firmly against the floor
surface. (p. 20)
Is the pedal connected correctly?
Make sure the pedal cord extending from the
stand is securely connected to the pedal
connector on the rear of the unit (p. 18).
Has a different function been assigned to the
pedal?
See "Assigning Functions to Pedals and Per-
formance Pads (Pedal Setting/User Func-
tions)" (p. 147).
Normal pedal operation is automatically en-
abled when the One Touch Program [Piano]
button is pressed (p. 20).
Could you be using a connection cable that
contains a resistor?
Use a connection cable that does not contain a
resistor.
Is the external display properly connected (p. 21)?
Is the external display's power turned on?
Are you using a display that is compatible
with the KR?
Refer to "Displays That Can Be Connected to
This Instrument" (p. 21).
Are the KR's settings correct?
Follow the instructions in "Selecting Images
To Be Shown on the KR-7 and External Dis-
plays (User Image Display) (KR-7)" (p. 154) to
set the "External Display" image. Also refer to
"Changing the Settings for Showing Images
with the External Display (External Display)
(KR-7)" (p. 153).
