IMPORTANT NOTES
291a
In addition to the items listed under “USING THE UNIT SAFELY”, please read
and observe the following:
Power Supply: Use of Batteries
304a
• When installing or replacing batteries,
always turn off the power on this unit
and disconnect any other devices you
may have connected. This way, you can
prevent malfunction and/or damage to
other devices.
306a
• A battery was installed in the unit before
it left the factory. The life of this battery
may be limited, however, since its
primary purpose was to enable testing.
307/921
• Before connecting this unit to other
devices, turn off the power to all units.
This will help prevent malfunctions
and/or damage to other devices.
Placement
352a
• This device may interfere with radio and
television reception. Do not use this
device in the vicinity of such receivers.
352b
• 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.
354a
• 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.
Maintenance
401a
• 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.
402
• Never use benzine, thinners, alcohol or
solvents of any kind, to avoid the possi-
bility of discoloration and/or defor-
mation.
Additional Precautions
551
• 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 write
down important data you have stored in
the unit's memory on paper.
452/552
• 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 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.
553
• 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.
556
• 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.
559a
• 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 equiv-
alent packaging materials.
Thank you, and congratulations on your choice of the BOSS DB-30 Dr. Beat METRONOME.
Before using this unit, carefully read the sections entitled: “USING THE UNIT SAFELY” and “IMPORTANT NOTES.” These sections provide important information concerning
the proper operation of the unit. Additionally, in order to feel assured that you have gained a good grasp of every feature provided by your new unit, this manual should be read
in its entirety. The manual should be saved and kept on hand as a convenient reference.
