IMPORTANT SAFEGUARDS

In addition to the careful attention devoted to quality standards in the manufacture of your
video product, safety is a major factor in the design of every instrument. However, safety is
your responsibility too. This sheet lists important information that will help to assure your
enjoyment and proper use of the video product and accessory equipment. Please read them
carefully before operating and using your video product.

Installation

1 Read and Follow Instructions – All the safety and operating instructions should be read before the

video product is operated. Follow all operating instructions.

2 Retain Instructions – The safety and operating instructions should be retained for future

reference.
3 Heed W arnings – Comply with all warnings on the video product and in the operating instructions.
4 Polarization – This video product is equipped with a polarized alternating -current line plug (a plug

having one blade wider than the other). This plug will fit into the power outlet only one way.

This is a safety feature. If you are unable to insert the plug fully into the outlet, try reversing the

plug. If the plug still fails to fit, contact your electrician to replace your obsolete outlet. To prevent

electric shock, do not use this polarized plug with an extension cord, receptacle, or other outlet

unless the blades can be fully inserted without blade exposure. If you need an extension cord,

use a polarized cord.
5 Power Sources – This video product should be operated only from the type of power source

indicated on the marking label. If you are not sure of the type of power supply to your home,

consult your video dealer or local power company. For video products intended to operate from

battery power, or other sources, refer to the operating instructions.

6 Overloading – Do not overload wall outlets or extension cords as this can result in a risk of fire or

electric shock. Overloaded AC outlets, extension cords, frayed power cords, damaged or cracked
wire insulation, and broken plugs are dangerous. They may result in a shock or fire hazard.
Periodically examine the cord, and if its appearance indicates damage or deteriorated insulation,
have it replaced by your service technician

P

ower-Cord Protection – Power-supply cords should be routed so that they are not likely to be
walked on or pinched by items placed upon or against them, paying particular attention to cords
at plugs, convenience receptacles, and the point where they exit from the video product.

8 Ventilation – Slots and openings in the case are provided for ventilation to ensure reliable

operation of the video product and to protect it from overheating. These openings must not be
blocked or covered. The openings should never be blocked by placing the video product on a bed,
sofa, rug, or other similar surface. This video product should never be placed near or over a
radiator or heat register. This video product should not be placed in a built-in installation such as
a bookcase or rack unless proper ventilation is provided or the video product manufacturer’s
instruction’s have been followed.

9 Attachments – Do not use attachments unless recommended by the video product manufacture

as they may cause a hazard.

10 Water and Moisture – Do not use this video product near water- for example, near a bath tub,

wash bowl, kitchen sink or laundry tub, in a wet basement, or near a swimming pool and the like.
Caution : Maintain electrical safety. Powerline operated equipment or accessories connected to
this unit should bear the UL listing mark or CSA certification mark on the accessory itself and
should not be modified so as to defeat the safety features. This will help avoid any potential
hazard from electrical shock or fire. If in doubt, contact qualified service personnel.

11 Accessories – Do not place this video product on an unstable cart, stand,

tripod, bracket, or table. The video product may fall, causing serious injury to
a child or adult as well as serious damage to the video product. Use this video
product only with a cart, stand, tripod, bracket, or table recommended by the
manufacturer or sold with the video product. Any mounting of the product
should follow the manufacturer’s instructions and use a mounting accessory
recommended by the manufacturer.

12 A video product and cart combination should be moved with care. Quick stops, excessive force,

and uneven surfaces may cause the video product and cart combination to overturn.

13 Power Lines – An outside antenna system should not be located in the vicinity of overhead power

lines, other electric light or power circuits, or where it can fall into such power lines or circuits.
When installing an outside antenna system, extreme care should be taken to keep from touch­ing or approaching such power lines or circuits as contact with them might be fatal. Installing an
outdoor antenna can be hazardous and should be left to a professional antenna installer.
