• Protect the unit from strong impact.
(Do not drop it!)
.................................................................................................................................
015
• 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.
.................................................................................................................................
016
• Before using the unit in a foreign country, consult with your

ventilation.
.................................................................................................................................
102c
• Always grasp only the plug on the AC adaptor cord when
plugging into, or unplugging from, an outlet or this unit.
.................................................................................................................................
103b
• 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.
.................................................................................................................................
104
• 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.
.................................................................................................................................
106
• Never climb on top of, nor place heavy objects on the unit.
.................................................................................................................................
107c
