Cleaning
When the unit gets dirty, wipe it with a
clean, soft dry cloth. If necessary, wipe it
with a soft cloth dampened with mild
soapy water, then a fresh cloth with clean
water. Wipe dry immediately with a dry
cloth. NEVER use benzene, aerosol
cleaners, thinner, alcohol or any other
volatile cleaning agent. Do not use
abrasive cleaners, as they may damage
the finish of metal parts. Avoid spraying
insecticide near the unit.

Moving The Unit
Before moving the unit, be certain to
disconnect any interconnection cords
with other components, and make
certain that you disconnect the unit from
the AC outlet.

Verify Line Voltage Before Use
Your HD740 has been designed for use
with 230-volt AC current. Connection to
a line voltage other than that for which it
is intended can create a safety and fire
hazard, and may damage the unit.

If you have any questions about the 
voltage requirements for your specific
model, or about the line voltage in your
area, contact your selling dealer before
plugging the unit into a wall outlet.

Do Not Use Extension Cords
We do not recommend that extension
cords be used with this product. As with
all electrical devices, do not run power
cords under rugs or carpets or place
heavy objects on them. Damaged power
cords should be replaced immediately by
an authorized service depot with cords
meeting factory specifications.

Handle the AC Power Cord Gently
When disconnecting the power cord from
an AC outlet, always pull the plug, never
pull the cord. If you do not intend to use
the unit for any considerable length of
time, disconnect the plug from the AC
outlet.

Do Not Open The Cabinet
There are no user-serviceable
components inside this product. Opening
the cabinet may present a shock hazard,
and any modification to the product will
void your guarantee. If water or any
metal object such as a paper clip, wire or
a staple accidentally falls inside the unit,
disconnect it from the AC power source
immediately, and consult an authorized
service station.
