PK-9

1. Important notes

In addition to the items listed under “Using the unit safely” on p. 4, 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 or
a motor (such as a refrigerator, washing machine, microwave
oven, or air conditioner). Depending on the way in which the elec-
trical 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.
•To prevent malfunction and equipment failure, always make sure
to turn off the power on all your equipment before you make any
connections.
•With the factory settings, the PK-9 will automatically be switched
off 240 minutes (4 hours) after you stop playing or operating the
unit. If you don't want the unit to turn off automatically, change
the “Auto Off” setting to “Off” as described on p. 16.

Note:

The settings you were editing will be lost when the unit is turned off. If you want to keep your settings, you must save your settings before turning the unit off.

Placement

•This device may interfere with radio and television reception. Do
not use it in the vicinity of such receivers.
•Noise may be produced if wireless communications devices, such
as cell phones, are operated in the vicinity of this unit. Such noise
could occur when receiving or initiating a call, or while conversing.
Should you experience such problems, you should relocate such
wireless devices so they are at a greater distance from this unit, or
switch them off.
•Do not expose the unit to direct sunlight, place it near devices that
radiate heat, leave it inside an enclosed vehicle, or otherwise sub-
ject it to temperature extremes. Excessive heat can deform or dis-
color the unit.
•When moved from one location to another where the temperature
and/or humidity is very different, water droplets (condensation)
may form inside the PK-9. 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.
•Do not allow objects to remain on top of the pedalboard. This can
be the cause of malfunction, such as keys ceasing to produce
sound.
•Depending on the material and temperature of the surface on
which you place the unit, its rubber feet may discolor or mar the
surface.
You can place a piece of felt or cloth under the rubber feet to pre-
vent this from happening. If you do so, please make sure that the
unit will not slip or move accidentally.
•Do not put anything that contains water on the PK-9. Also, avoid
the use of insecticides, perfumes, alcohol, nail polish, spray cans,
etc., near the unit. Swiftly wipe away any liquid that spills on the
unit using a dry, soft cloth.

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 benzene, thinner, alcohol or solvents of any kind, to
avoid the possibility of discoloration and/or deformation.

Repairs and Data

•Please be aware that all data contained in the unit's memory may
be lost when the unit is sent for repairs. Important data should
always be backed up in another MIDI device (e.g., a sequencer), or
written down on paper (when possible). During repairs, due care is
taken to avoid the loss of data. However, in certain cases (such as
when circuitry related to memory itself is out of order), we regret
that it may not be possible to restore the data, and Roland
assumes no liability concerning such loss of data.

Additional precautions

•Please be aware that the contents of memory can be irretrievably
lost as a result of a malfunction, or the improper operation of the
unit. To protect yourself against the risk of loosing important data,
we recommend that you periodically save a backup copy of impor-
tant data you have stored in the unit's memory, in another MIDI
device (e.g., a sequencer).
•Unfortunately, it may be impossible to restore the contents of data
that was stored in the unit’s memory once it has been lost. Roland
Corporation assumes no liability concerning such loss of data.
•Use a reasonable amount of care when using the PK-9’s buttons,
other controls and jacks/connectors. Rough handling can lead to
malfunctions.
•Never strike or apply strong pressure to the display.
•When disconnecting all cables, grasp the connector itself—never
pull on the cable. This way you will avoid causing shorts, or dam-
age to the cable’s internal elements.
•The sound of pedals being struck and vibrations produced by play-
ing an instrument can be transmitted through a floor or wall to an
unexpected extent. Please take care not to cause annoyance to
others nearby.
•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.
•Use only the specified expression pedal (Roland EV-series, sold
separately) or pedal switch (Roland DP-series, BOSS FS-5U). By
connecting any other expression pedal or footswitch, you risk
causing malfunction and/or damage the unit.
•When you operate the pedals, please be careful not to get your
fingers pinched between the movable part and the panel. In places
where small children are present, make sure that an adult provides
supervision and guidance.
