1 Important safety instructions & FCC information 1.1 Safety The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the appliance. The lighting flash with arrowhead symbol, Within an equilateral triangle, is intended to alert the user to the presence of un-insulated “dangerous voltage” within the product’s enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons. CAUTION :TO REDUCE THE RISK OF ELECTRIC SHOK DO NOT REMOVE COVER(OR BACK) NO USER-SERVICEABLE PARTS INSIDE. REFER SERVICING TO QUALIFIED SERVICE PERSONNEL. FOR YOUR SAFETY - The space around the receiver should be clear to allow for proper ventilation of the receiver. - Do not cover the receiver or place it on a unit that emits heat - Use a damp soft cloth to clean the casing. - Do not connect or disconnect cables when the receiver is plugged in. - Do not remove the cover. - Do not allow the unit to be exposed to hot, cold or humid conditions. - Never allow liquids, spray or other materials to come into contact with the inside of the receiver. Outdoor Use Marking Warning : To prevent fire of electric shock, do not expose this appliance to rain or moisture. Cable System Installation Marking Note to CATV System Installer: This reminder is provided to call CATV system installer’s attention to Article 820-40 of the NEC that provides guidelines for proper grounding and, in particular, specifies that the cable ground shall be connected to the grounding system of the building, as close to the point of cable entry as practical Polarized Attachment plug Marking Caution : To prevent electric shock, match wide blade of plug to wide slot, fully insert. Important Safety Instruction 1) Read Instructions : All the safety and operating instructions should be read before the product is operated. 2) Retain Instructions : The safety and operating instruction should be retained for future reference. 3) Head Warnings : All warnings on the product and in the operating instructions should be adhered to. 4) Follow instructions : All operating and use instructions should be followed. 5) Cleaning : Unplug this product from the wall outlet before cleaning. Do not use liquid cleaners or aerosol cleaner. Use a damp cloth for cleaning. 6) Exception : A product that is meant or uninterrupted service and that for some specific reason, such as the possibility of the loss of and authorization code for c CATV converter, is not intended to be unplugged by the user for cleaning or any other purpose, may exclude the reference to unplugging the product in the cleaning description otherwise required in this article. 7) Attachment : Do not use attachments not recommended by the product manufacturer as they may cause hazards. 8) Water and Moisture : Do not use the product near water for example, near a bath, wash bowl, kitchen sink, or laundry tub ; in a wet basement; or rear a swimming pool; and the like. 9) Accessories : Do not place this product on an unstable cart, stand, tripod, bracket, or table. This product may fall, causing serious injury to a child or adult, and serious damage to the product. 10) A product and cart combination should be moved with care. Quick stops, excessive force, and uneven surface may cause the product and cart combination to overturn. Please refer to picture 1 in the end of this chapter. 11) Ventilation : Slot and openings in the cabinet are provided for ventilation and to ensure reliable operation of the product and to protest it from overheating, and these openings must not be blocked by covered. The 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’s instructions have been adhered to. 12) Power sources : This 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 product dealer or local power company. For products intended to operate from battery power, or other sources, refer to the perating instructions. 13) Grounding or Polarization : This product may be equipped with a polarized alternating current line plug(a plug having on blade wider than the other). This plug will fit into the power outlet only on way. This is a safety feature. If you are unable to insert the plug gully into the outlet, try reversing the plug. If the plug should still fail to fir, contact your electrician to replace your obsolete outlet. Do not defeat the safety purpose of the polarizing plug. Alternate Warning : This product is equipped with a three-wire grounding-type plug, a plug having a third (grounding) pin. This plug will only fit into a grounding-type power outlet. This is a safety feature. If you are unable to insert the plug into the outlet, contact your electrician to replace your obsolete outlet. Do not defeat the safety purpose of the grounding-type plug. 14) Power-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 product. 15) Protective Attachment Plug : The product is equipped with an attachment plug having overload protection. This is a safety feature. See instruction Manual for replacement or resetting of protective device. If replacement of the plug is required, be sure the service technician has used a replacement plug specified by the mnufactu- rer that has the same overload protection as the original plug. 16) Outdoor Antenna Grounding : If an outside antenna or cable system is connected to the product, be sure the antenna or cable system is grounded so a…
