7. Water and moisture—Do not use the product near water, such as bathtub, washbasin, kitchen

excessive force and uneven floor surface can cause the product to fall from the
cart.
10.Ventilation—The vents and other openings in the cabinet are designed for
ventilation. Do not cover or block these vents and openings since insufficient
ventilation can cause overheating and/or shorten the life of the product. Do not
place the product on a bed, sofa, rug or other similar surface, since they can
block ventilation openings. This product is not designed for built-in installation; do
not place the product in an enclosed place such as a bookcase or rack, unless
proper ventilation is provided or the manufacturer’s instructions are followed.
11.Power source—This product must operate on a power source specified on the
specification label. If you are not sure of the type of power supply used in your home, consult your
dealer or local power company. For units designed to operate on batteries or another power
source, refer to the operating instructions.
12.Power cord protection—The power cords must be routed properly to prevent people from stepping
on them or objects from resting on them. Check the cords at the plugs and product.
13.If the AC adapter is misplaced or needs to be replaced, obtain the same type of adapter from a
SHARP service center or your dealer.
14.If you plan to use a 13-VDC power supply unit other than the AC adapter supplied with the
product, make sure the power supply unit provides stable voltage with minimum fluctuations.
Unstable power supply can cause problems in the product.
15. The LCD panel used in this product is made of glass. Therefore, it can break when the product is

electric shock.
