Safety precautions (continued) FCC Warning This equipment may generate or use radio frequency energy. Changes or modifications to this equipment may cause harmful interference unless the modifications are expressly approved in this instruction manual. The user could lose the authority to operate this equipment if an unauthorized change or modification is made. Note This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment may cause harmful interference to radio communications if it is not installed and used in accordance with these instructions. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one of more of the following measures: • Reorient or relocate the receiving antenna • Increase the separation between the equipment and receiver • Connect the equipment into an outlet on a circuit differ- ent from that to which the receiver is connected • Consult the dealer or an experienced radio/TV techni- cian for help Cleaning the DT-7000S If the tuner becomes dirty, turn its power off and wipe it clean with a soft dry cloth. Do not use hard cloths or paint thinner, alcohol, or other volatile solvents to clean the tuner. These may cause damage or remove indicator characters. Important Safeguards Power Source - Connect the DT-7000S only to a 120V 60Hz AC power supply. If you are not sure of the type of power supply to your home, consult your local power company. Power cord protection - Route the power cord so that it is not likely to be walked-on or pinched by items placed upon or against it. CAUTION - Polarization - The DT-7000S is fitted with a polarized AC plug (having one blade wider than the other). This plug will fit into the 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 it should still fail to fit, contact your electrician to replace your obsolete outlet. Do not defeat the safety purpose of the polarized plug. Ventilation - Do not block the ventilation openings on the back of the DT-7000S. Place the tuner at least 4 inches away from the wall. When placing the DT-7000S in a rack or built-in installation, take care to provide proper ventilation. Water & moisture - Do not use the DT-7000S near water; do not expose it to dripping or splashing liquids; do not place objects filled with liquids, such as vases, on the tuner. Temperature - The DT-7000S may not work properly if used at extremely low, or freezing temperatures. The ideal ambient temperature is above 41°F (+5°C). Heat - Do not install the DT-7000S near heat sources such as radiators, heat registers, stoves or other appliances that produce heat. Electric shock - Do not place objects or spill liquids into the ventilation openings. If a metal object comes into contact with the inside of the tuner, a dangerous electric shock may result. Never remove the enclosure. If internal parts are touched accidentally, a serious electric shock could occur. Lightning - Unplug the DT-7000S from the wall outlet and disconnect the antenna when it will be unused for a long period of time. Damage requiring service - The DT-7000S should be serviced by qualified service personnel when: • The power cord or plug has been damaged • Objects have fallen, or liquid has been spilled into the tuner • The tuner has been exposed to rain or water • The tuner does not appear to operate normally by following the instructions in this manual. • The tuner has been dropped, or its chassis damaged. • The tuner exhibits a marked change in performance. Outdoor antenna grounding - If an outside antenna is connected to the DT-7000S, be sure the antenna system is grounded so as to provide some protection against voltage surges and built-up static charges. Article 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. See the illustration below. 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 into 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. Replacement parts - When replacement parts are required, be sure the service technician has used replacement parts specified by the manufacturer or that have the same characteristics as the original parts. Unauthorized substitutions may result in fire, electric shock, or other hazards. Attachments - Only use attachments specified by Kenwood with the DT-7000S. Accessories - Use only with the cart, stand, tripod, or bracket recommended by Kenwood or sold with the DT-7000S. Do not place the tuner on an unstable cart, stand, tripod, bracket or table. When a cart is used, use caution when moving it to avoid tip-overs that can cause injuries. DT-7000S Instruction Manual 3
