This will prevent damage to the unit due to lightning and power line surges. 14. POWER LINES An outside antenna system should not be located in the vicinity of overhead power lines or other electric light or power circuits, or where it can fall onto or against such power lines or circuits. When installing an outside antenna system, extreme care should be taken to keep from touching such power lines or circuits, as contact with them might be fatal. 15. OVERLOADING Do not overload wall outlets and extension cords, as this can result in a risk of fire or electric shock. 16. OBJECT AND LIQUID ENTRY Do not push objects through any openings in this unit, as they may touch dangerous voltage points or short out parts that could result in fire or electric shock. Never spill or spray any type of liquid into the unit. 17. OUTDOOR ANTENNA GROUNDING If an outside antenna or cable system is connected to the unit, be sure the antenna or cable system is grounded to provide some protection against voltage surges and built-up static charges, Section 810 of the National Electrical Code, ANSI/NFPA 70, provides information with respect to proper grounding of the mast and supporting structure, grounding of the lead-in wire to an antenna discharge unit, size of grounding conductors, location of antenna discharge unit, connection to grounding electrodes, and requirements for the grounding electrode. 18. SERVICING Do not attempt to service this unit yourself as opening or removing covers may expose you to dangerous voltage or other hazards. Refer all servicing to qualified service personnel. For example: a. When the power-supply cord or plug is damaged. b. If liquid has been spilled, or objects have fallen into the unit. c. If the unit has been exposed to rain or water. d.

For maximum protection, repack the unit as it was originally packed at the factory. Do not use volatile liquids, such as insect spray, near the DVD/VCR. Do not leave rubber or plastic products to contact the DVD/VCR for a prolonged period. They will leave marks on the finish. The top and rear panels of the DVD/VCR may become warm after a long period of use. This is not a malfunction. When the DVD/VCR is not in use, be sure to remove the disc and the video cassette turn off the power. If you do not use the DVD/VCR for a long period, the unit may not function properly in the future. Turn on and use the DVD/VCR occasionally. Notes on locating Place the DVD/VCR on a level surface. Do not use it on a shaky or unstable surface such as a wobbling table or inclined stand. The loaded disc or the video tape may become dis-aligned and damage the DVD/ VCR. When you place this DVD/VCR near a TV, radio, or VCR, the playback picture may become poor and the sound may be distorted. In this case, place the DVD/ VCR away from the TV, radio, or VCR. Notes on cleaning Moisture condensation damages the DVD/VCR. Please read the following carefully. Moisture condensation occurs, for example, when you pour a cold drink into a glass on a warm day. Drops of water form on the outside of the glass. In the same way, moisture may condense on the head drum or the optical pick-up lens inside this unit, one of the most crucial internal parts of the DVD/VCR. Exacmopnldeeonfsmatoioisnt!ure Tape Head drum Moisture condensation occurs during the following cases. When you bring the DVD/VCR directly from a cold place to a warm place. When you use the DVD/VCR in a room where you just turned on the heater, or a place where the cold wind from the air conditioner directly hits the unit. In summer, when you use the DVD/VCR in a hot and humid place just after you move the unit from an air conditioned room. When you use the DVD/VCR in a humid place. It's too warm! Use a soft, dry cloth for cleaning. For stubborn dirt, soak the cloth in a weak detergent solution, wring well and wipe. Use a dry cloth to wipe it dry.
