Case
Cause/Remedy
The power doesn’t
come on.
Is the power cord connected and plugged in
correctly? (p. 16)
The button doesn’t
work.
Is the panel locked? (p. 152)
Turn the power off, then back on.
Nothing appears
on screen.
The KF-7 uses a liquid-crystal screen, so text
may not be displayed when the ambient tem-
perature is below freezing.
Vertical lines ap-
pear in the screen/
Color is “washed
out” at the edges of
the screen
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. 19).
The touch screen
doesn’t respond
correctly.
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. 151) to
correct the positioning.
Depressing a ped-
al has no effect, or
the pedal effect
doesn’t stop.
Is the pedal connected correctly?
Make sure the pedal cord is securely connect-
ed to the pedal connector on the rear of the
unit (p. 16).
Has a different function been assigned to the
pedal?
See “Assigning Functions to Pedals and Per-
formance Pads (Pedal Setting/User Func-
tions)” (p. 143).
Normal pedal operation is automatically en-
abled when the One Touch Program [Piano]
button is pressed (p. 20).

The volume level
of the instrument
connected to Input
jacks is too low.
Could you be using a connection cable that
contains a resistor?
Use a connection cable that does not contain a
resistor.
No sound is heard
No sound is heard.
Is the volume level of the KF-7 (p. 18) or con-
nected device turned all the way down?
Are headphones plugged in? (p. 18)
Has the Balance knob been moved all the way
to the right or left?
Has the volume been set to “0” using the Part
Balance? (p. 63)
Are all sliders in the Equalizer screen at the
minimum level? (p. 30)
Has the footage been adjusted so that all fre-
quency components aren’t sounded? (p. 15 in
the Quick Start)
No sound is heard
(when a MIDI in-
strument is con-
nected).
Have all devices been switched on?
Are the MIDI cables connected correctly? (p.
154)
Does the MIDI channel match the connected
instrument? (p. 156)
Is the Computer switch on the rear panel set
to “MIDI”? (p. 159)
You cannot use a
connected MIDI
device and com-
puter simulta-
neously
The MIDI connectors and the computer con-
nector cannot be used at the same time.
Confirm that the computer switch is set to
“MIDI” when a MIDI device is connected to
the MIDI connector, and to either “MAC,”
“PC-1,” “PC-2,” when a computer is connect-
ed to the Computer connector (p. 159).
No sound is heard
when the keyboard
is played.
Has Local Control been set to “Off”?
When Local Control is set to Off, no sound is
produced by playing the keyboard.
Set Local Control to On. (p. 156)
Not all played
notes are sound-
ed.
The maximum number of notes that the KF-7
can play simultaneously is 128. Frequent use
of the damper pedal during automatic accom-
paniment or when playing along with a song
on floppy disk may result in performance
data with too many notes, causing some notes
to drop out.
The sound is strange
Sounds are heard
twice (doubled)
when the keyboard
is played.
Is the KF-7 in layer play? (p. 24)
When the KF-7 is connected to an external se-
quencer, set it to the Local OFF mode
(p. 156). Alternatively, the sequencer could be
set so its Soft Thru feature is OFF.
