Roland Electronic Keyboard PK 7 User Guide

Owner’s Manual  
Before using this unit,  
Thank you, and congratulations on your choice of the Roland PK-7 Pedal Keyboard.  
The PK-7 is a pedal keyboard unit which was designed especially for the VK-88/VK-  
8. It provides a pedal keyboard, an expression pedal for dynamic volume changes, foot  
switches that let you control various functions of the VK-88/VK-8 by foot, and a hold  
pedal to sustain the sound.  
carefully read the sections  
entitled: “USING THE UNIT  
SAFELY” (p. 2, 3) and  
“IMPORTANT NOTES” (p. 4).  
These sections provide  
important information  
Features  
concerning the proper  
operation of the unit.  
Twenty-note pedal keyboard and removable expression pedal  
The PK-7 features a twenty-note pedal keyboard for maximum enjoyment of organ  
playing. The built-in expression pedal can be removed from the pedal keyboard unit  
to make the unit more compact for transportation.  
Additionally, in order to feel  
assured that you have gained  
a good grasp of every feature  
provided by your new unit,  
this Owner’s Manual should  
be read in its entirety. The  
manual should be saved and  
kept on hand as a convenient  
reference.  
Foot switches for controlling the VK-88/VK-8  
Two foot switches are built into the expression pedal. During a performance, you can  
switch the settings of the VK-88/VK-8 without removing your foot from the  
expression pedal or your hands from the keyboard.  
Hold pedal  
A hold pedal is located where it can be easily operated by your right foot, for  
additional expressive possibilities when playing sustain-type sounds.  
Single-cable connection to the VK-88  
When connecting the PK-7 to the VK-88, the PK cable that is supplied with the VK-88  
is the only connection required–no need for MIDI cables, analog cables, or an AC  
power adaptor. This makes setup quick and easy.

In households with small children, an adult  
should provide supervision until the child is  
capable of following all the rules essential for the  
safe operation of the unit.  
The unit and the AC adaptor should be located so  
their location or position does not interfere with  
their proper ventilation.  
..........................................................................................................  
..........................................................................................................  
Always grasp only the plug on the AC adaptor  
cord when plugging into, or unplugging from, an  
outlet or this unit.  
Protect the unit from strong impact.  
(Do not drop it!)  
..........................................................................................................  
103b  
..........................................................................................................  
At regular intervals, you should unplug the AC  
adaptor and clean it by using a dry cloth to wipe  
all dust and other accumulations away from its  
prongs. Also, disconnect the power plug from the  
power outlet whenever the unit is to remain  
unused for an extended period of time. Any  
accumulation of dust between the power plug and  
the power outlet can result in poor insulation and  
lead to fire  
Do not force the unit’s power-supply cord to share  
an outlet with an unreasonable number of other  
devices. Be especially careful when using  
extension cords—the total power used by all  
devices you have connected to the extension cord’s  
outlet must never exceed the power rating (watts/  
amperes) for the extension cord. Excessive loads  
can cause the insulation on the cord to heat up and  
eventually melt through.  
..........................................................................................................  
..........................................................................................................  
Try to prevent cords and cables from becoming  
entangled. Also, all cords and cables should be  
placed so they are out of the reach of children.  
Before using the unit in a foreign country, consult  
with your retailer, the nearest Roland Service  
Center, or an authorized Roland distributor, as  
listed on the “Information” page.  
..........................................................................................................  
Never climb on top of, nor place heavy objects on  
the unit.  
..........................................................................................................  
..........................................................................................................  
Never handle the AC adaptor body, or its output  
plugs, with wet hands when plugging into, or  
unplugging from, an outlet or this unit.  
..........................................................................................................  
Before moving the unit, disconnect the AC adaptor  
and all cords coming from external devices.  
..........................................................................................................  
Before cleaning the unit, turn off the power and  
unplug the AC adaptor from the outlet.  
..........................................................................................................  
Whenever you suspect the possibility of lightning  
in your area, disconnect the AC adaptor from the  
outlet.  
..........................................................................................................  
Be careful when handling the expression pedal  
unit or attaching/detaching the expression pedal  
unit to/from the PK-7 so you do not get your  
fingers pinched.

Important Notes  
In addition to the items listed under “USING THE UNIT SAFELY” on page 2 and 3, please read and observe the following:  
Power Supply  
Do not connect this unit to same electrical outlet that is being used by an electrical appliance that is controlled by an inverter  
(such as a refrigerator, washing machine, microwave oven, or air conditioner), or that contains a motor. Depending on the  
way in which the electrical appliance is used, power supply noise may cause this unit to malfunction or may produce audible  
noise. If it is not practical to use a separate electrical outlet, connect a power supply noise filter between this unit and the  
electrical outlet.  
The AC adaptor will begin to generate heat after long hours of consecutive use. This is normal, and is not a cause for concern.  
Before connecting this unit to other devices, turn off the power to all units. This will help prevent malfunctions and/or  
damage to speakers or other devices.  
Placement  
This device may interfere with radio and television reception. Do not use this device in the vicinity of such receivers.  
Do not expose the unit to direct sunlight, place it near devices that radiate heat, leave it inside an enclosed vehicle, or  
otherwise subject it to temperature extremes. Excessive heat can deform or discolor the unit.  
355b  
When moved from one location to another where the temperature and/or humidity is very different, water droplets  
(condensation) may form inside the unit. Damage or malfunction may result if you attempt to use the unit in this condition.  
Therefore, before using the unit, you must allow it to stand for several hours, until the condensation has completely  
evaporated.  
358 Do not allow objects to remain on top of the keyboard. This can be the cause of malfunction, such as keys ceasing to produce  
sound.  
Maintenance  
For everyday cleaning wipe the unit with a soft, dry cloth or one that has been slightly dampened with water. To remove  
stubborn dirt, use a cloth impregnated with a mild, non-abrasive detergent. Afterwards, be sure to wipe the unit thoroughly  
with a soft, dry cloth.  
Never use benzine, thinners, alcohol or solvents of any kind, to avoid the possibility of discoloration and/or deformation.  
Additional Precautions  
Use a reasonable amount of care when using the unit’s buttons, sliders, or other controls; and when using its jacks and  
connectors. Rough handling can lead to malfunctions.  
When connecting / disconnecting all cables, grasp the connector itself—never pull on the cable. This way you will avoid  
causing shorts, or damage to the cable’s internal elements.  
558b  
To avoid disturbing your neighbors, try to keep the unit’s volume at reasonable levels (especially when it is late at night).  
When you need to transport the unit, package it in the box (including padding) that it came in, if possible. Otherwise, you will  
need to use equivalent packaging materials.
