Boss BR-80 Owner's Manual page 5

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.
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.
Included batteries must never be recharged, heated,
taken apart, or thrown into fire or water.
Never expose batteries to excessive heat such as
sunshine, fire or the like.
Incorrect handling of batteries, rechargeable
batteries, or a battery charger can cause leakage,
overheating, fire, or explosion. Before use, you must
read and strictly observe all of the precautions that
accompany the batteries, rechargeable batteries, or
battery charger.
When using rechargeable batteries and a charger,
use only the combination of rechargeable batteries
and charger specified by the battery manufacturer.
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 output plug or the body of
the AC adaptor when plugging into, or unplugging
from, this unit or an outlet.
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.
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.
USING THE UNIT SAFELY
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 (p. 41).
Whenever you suspect the possibility of lightning
in your area, disconnect the AC adaptor from the
outlet.
If used improperly, batteries may explode or leak
and cause damage or injury. In the interest of safety,
please read and observe the following precautions
(p. 38).
• Carefully follow the installation instructions for
batteries, and make sure you observe the correct
polarity.
• Avoid using new batteries together with used
ones. In addition, avoid mixing different types
of batteries.
• Remove the batteries whenever the unit is to
remain unused for an extended period of time.
• If a battery has leaked, use a soft piece of cloth or
paper towel to wipe all remnants of the discharge
from the battery compartment. Then install new
batteries. To avoid inflammation of the skin, make
sure that none of the battery discharge gets onto
your hands or skin.
Exercise the utmost caution so that none of the
discharge gets near your eyes. Immediately rinse
the affected area with running water if any of the
discharge has entered the eyes.
• Never keep batteries together with metallic
objects such as ballpoint pens, necklaces,
hairpins, etc.
Used batteries must be disposed of in compliance
with whatever regulations for their safe disposal
that may be observed in the region in which you
live.
Keep the included SD card in a safe place out of
children's reach, so there is no chance of them being
swallowed accidentally.
