CAUTION concerning the Power Cord
Most appliances recommend they be placed upon
a dedicated circuit;
That is, a single outlet circuit which powers only
that appliance and has no additional outlets or
branch circuits. Check the specication page of this
owner’s manual to be certain. Do not overload wall
outlets. Overloaded wall outlets, loose or damaged
wall outlets, extension cords, frayed power cords, or
damaged or cracked wire insulation are dangerous.
Any of these conditions could result in electric
shock or re. Periodically examine the cord of your
appliance, and if its appearance indicates damage
or deterioration, unplug it, discontinue use of the
appliance, and have the cord replaced with an
exact replacement part by an authorized service
center. Protect the power cord from physical or
mechanical abuse, such as being twisted, kinked,
pinched, closed in a door, or walked upon. Pay
particular attention to plugs, wall outlets, and
the point where the cord exits the appliance. To
disconnect power from the mains, pull out the
mains cord plug. When installing the product,
ensure that the plug is easily accessible.
This device is equipped with a portable battery or
accumulator.
Safety way to remove the battery or the

container at designated collection points. Do
not dispose of batteries or battery together with
other waste. It is recommended that you use
local, free reimbursement systems batteries and
accumulators. The battery shall not be exposed to
excessive heat such as sunshine, re or the like.
Grounding
(Except for devices which are not grounded.)
Ensure that you connect the earth ground wire
to prevent possible electric shock (i.e. a Audio
with a three-prong grounded AC plug must be
connected to a three-prong grounded AC outlet).
If grounding methods are not possible, have a
qualied electrician install a separate circuit breaker.
Do not try to ground the unit by connecting it to
telephone wires, lightening rods, or gas pipes.
