USING THE UNIT SAFELY
Avoid extended use at high volume
This unit, either alone or in combination with an

for a long period of time at a high volume level,
or at a level that is uncomfortable. If you
experience any hearing loss or ringing in the
ears, you should immediately stop using the unit,
and consult an audiologist.

of other devices
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.

Periodically wipe the dust off the AC adaptor plug
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.
