The KR105 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
crystal display, and do not indicate a
malfunction. They can be minimized by
adjusting the brightness of the screen (p.
18).
The positioning of the touch screen may
become displaced if some time has passed
since it was last used. Take a look at
"Calibrating the Touch Screen (Touch
Screen)" (p. 139) to correct the positioning.
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. 15).
Has a different function been assigned to
the pedal?
See "Assigning Functions to Pedals and
Performance Pads (Pedal Setting/User
Functions)" (p. 126).
Normal pedal operation is automatically
enabled when the One Touch Program
[Piano] button is pressed (p. 16).
Could you be using a connection cable that
contains a resistor?
Use a connection cable that does not
contain a resistor.

Do you have different external devices
plugged into different power outlets?
When connecting external devices, always
draw power from the same outlet.
Adjusting the panel's [Volume] knob may
cause the mic volume to change.

Is the volume level of the KR105 (p. 17) or
connected device turned all the way down?

the keyboard's speaker stops playing.

15 in the Quick Start)
