Using The Unit Safely; Important Notes - Boss AC-22LX Owner's Manual

USING THE UNIT SAFELY

WARNING
Use only the supplied AC adaptor and the correct
voltage
Be sure to use only the AC adaptor
supplied with the unit. Also, make
sure the line voltage at the installation
matches the input voltage specified on
the AC adaptor's body. Other AC adaptors
may use a different polarity, or be designed for a
different voltage, so their use could result in damage,
malfunction, or electric shock.
Use only the supplied power cord
Use only the attached power cord. Also,
the supplied power cord must not be
used with any other device.
Turn the unit off before installing expansion
boards
Before installing the BT-DUAL, you must
first always turn off the AC-22LX and
unplug the AC adaptor.

IMPORTANT NOTES

Power Supply
• Place the AC adaptor so the side with the indicator
faces upwards. The indicator will light when you
plug the AC adaptor into an AC outlet.
Power Supply: Use of Batteries
• If the batteries run extremely low, the sound may
distort / interruptions in the sound may occur
at high volume levels, but this does not indicate
a malfunction. If this occurs, please replace the
batteries / use the included AC adaptor.
• If operating this unit on batteries, please use
alkaline batteries, Ni-MH batteries.
• If operating this unit on batteries, please disconnect
the AC adaptor from this unit.
Placement
• Do not allow lighting devices that normally are
used while their light source is very close to the unit
(such as a piano light), or powerful spotlights to
shine upon the same area of the unit for extended
periods of time. Excessive heat can deform or
discolor the unit.
• Depending on the material and temperature of the
surface on which you place the unit, its rubber feet
may discolor or mar the surface.
Maintenance
• To clean the unit, use a dry, soft cloth; or one that
is slightly dampened. Try to wipe the entire surface
using an equal amount of strength, moving the
cloth along with the grain of the wood. Rubbing
too hard in the same area can damage the finish.
