Roland KF-7 业主指南

 

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.

 

Is the volume level of the KF-7 (p. 18) or con-
nected device turned all the way down?

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?

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.

 

Sounds are heard 

twice (doubled) 

when the keyboard 

is played. 

 

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.

 

If you think there’s a problem, read this first.
