At regular intervals, you should unplug the power plug and
clean it by using a dry cloth to wipe all dust and other accumula-
tions 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.

•
Do not connect this unit to same electrical outlet that is being used by an
electrical appliance that is controlled by an inverter (such as a refrigerator,
washing machine, microwave oven, or air conditioner), or that contains a
motor. Depending on the way in which the electrical 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.

Although the LEDs are switched off when the POWER switch is switched
off, this does not mean that the unit has been completely disconnected
from the source of power. If you need to turn off the power completely,
first turn off the POWER switch, then unplug the power cord from the
power outlet. For this reason, the outlet into which you choose to connect
the power cord’s plug should be one that is within easy reach and readily
accessible.

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 temper-
ature extremes. Also, 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.

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.
