cart, stand, tripod, bracket, or table. Use only with
carts, stands, tripods, brackets, or tables recom-
mended by the manufacturer or sold with the

tilation to ensure reliable operation of the product and to protect it
from overheating. These openings should never be blocked by placing
the product on a bed, sofa, rug, or other similar surface. This product
should not be placed in a built-in installation such as a bookcase or
rack unless proper ventilation is provided or the manufacturer in-
structions have been adhered to.

power source indicated on the rating label. If you are not sure of the
type of power supply to your home, consult your product dealer or
local power company. For products intended to operate from battery
power or other sources, refer to the operating instructions.
11. Grounding or Polarization: This product may be equipped with a po-
larized alternating-current line plug that has one blade wider than
the other. This plug will only t into the power outlet in one direction.
This is a safety feature. If you are unable to insert the plug fully into
the outlet, try reversing the direction of the plug. If the plug should
still fail to t, contact an electrician to replace the obsolete outlet. Do
not defeat the safety purpose of the polarized plug.
12. Power-Cord Protection: Power supply cords should be routed so that

tachment plug with overload protection. This is a safety feature. See
the operating instructions for replacement or directions to reset the
protective device. If replacement of the plug is required, be sure the
service technician has used a replacement plug that has the same over-
load protection as the original plug as specied by the manufacturer.
14. Lightning: For added protection for this product, unplug it from the
wall outlet during a lightning storm or when it is left unattended and
unused for long periods oftime. This will prevent damage to the prod-
uct due to lightning or power-line surges.
15. Overloading: Do not overload wall outlets, extension cords, or inte-
gral convenience receptacles as this can result in a risk of re or elec-
tric shock.
16. Object and Liquid Entry: Never push objects of any kind into this prod-
uct through openings as they may touch dangerous voltage points or
short-out parts that could result in a re or electric shock. Never spill
liquid of any kind on the product.
17. Servicing: Do not attempt to service this product yourself as open-
ing or removing covers may expose you to dangerous voltage or other
hazards. Refer all servicing to qualied service personnel.
18. Damage Requiring Service: Unplug this product from the wall outlet
and refer servicing to qualied service personnel under the follow-
ing conditions: a) when the power-supply or plug is damaged; b) if
liquid has been spilled or if objects have fallen into the product; c) if
the product has been exposed to rain or water; d) if the product does
not operate normally by following the operating instructions. Adjust
only those controls that are covered by the operating instructions as
improper adjustment of other controls may result in damage and will
often require extensive work by a qualied technician to restore the
product to its normal operation; e) if the product has been dropped or
damaged in any way; f) when the product exhibits a distinct change in
performance—this indicates a need for service.
19. Replacement Parts: When replacement parts are required, be sure
