2IMPORTANT SAFETY INSTRUCTIONSSafety1.Power source— Connect the unit to a power source of the typedescribed in these instructions or as marked on the unit.2.Polarization— The unit is equipped with a polarized power plugwhere one blade is wider than the other. This safety feature ensuresthat the plug fits into your household AC outlet only one way. If theplug doesn’t fit one way, try reversing it. If the plug still doesn’t fit,contact an electrician to replace the obsolete outlet. Do not attemptto defeat the safety purpose of the plug.3.Power cord protection— Route the AC power supply cord so that itwill not be walked on or pinched by items placed on or against it.Never take hold of the plug or cord with wet hands. Always grasp theplug body firmly when connecting and disconnecting it.4.Overloading— When connecting the AC power supply cord, becareful not to overload the household AC outlet, extension cord, oroutlet from any other device as this can result in fire or electric shock.5.Nonuse periods— Turn the unit off when it is not in use. Unplug theunit from the household AC outlet if it is not to be used for a longtime. Unplug the unit during lightning storms.6.Attachments and accessories— Use only the attachments andaccessories recommended in these operating instructions.Read these operating instructions carefully before using the unit. Follow the safety instructions on the unit and the safety precautions listed below.Keep these operating instructions handy for future reference.InstallationEnvironmentELECTRICSERVICEEQUIPMENTGROUNDCLAMPANTENNALEAD INWIREANTENNADISCHARGE UNIT(NEC SECTION 810-20)GROUNDING CONDUCTORS(NEC SECTION 810-21)GROUND CLAMPSPOWER SERVICE GROUNDINGELECTRODE SYSTEM(NEC ART 250, PART H)NEC— NATIONAL ELECTRICAL CODE1.Water and moisture— Do not use the unit near water, such as neara bathtub or swimming pool. Avoid damp basements.2.Heat— Situate the unit away from heat sources, such as radiators.Do not situate where temperatures fall below 5° C (41° F) or riseabove 35° C (95° F).3.Power lines— Take care when setting up an outdoor antenna that itis not near overhead power lines, electric lights, or electrical circuits,and that there is no danger of the antenna falling on power lines,electric lights, or electrical circuits. When installing an outdoorantenna, take extreme care not to touch such power lines or circuits,as contact with them can be fatal.Placement1.Ventilation— Situate the unit so that it receives proper ventilation. Donot install in a confined space such as a bookcase or cabinet. Allowat least 10 cm (4 inches) clearance from the rear of the unit. Toprevent the risk of electric shock or fire due to overheating ensurecurtains and other materials do not obstruct the unit’s ventilation.2.Foreign material— Ensure objects and liquids do not get into theunit. Avoid exposing the unit to excessive smoke, dust, mechanicalvibration, and shock.3.Magnetism— Situate the unit away from equipment and devices thatgenerate strong magnetic fields.4.Stacking— Do not place heavy objects on top of this unit.5.Surface— Place the unit on a flat, level surface.6.Carts and stands— Use the unit only with cartsand stands recommended by the manufacturer.Move carts with care. Sudden stops, excessiveforce, and uneven surfaces can cause carts tooverturn.7.Wall and ceiling mounting— Do not mount theunit on walls or ceilings unless specified in the instructions.Maintenance(See page 17 for details.)Unplug the unit from the household AC outlet before cleaning.Clean with a damp cloth.Do not use abrasive pads, scouring powders, or solvents.Service1.Damage requiring service— The unit should be serviced byqualified service personnel if:(a) The AC power supply cord or the plug has been damaged; or(b) Objects or liquids have gotten into the unit; or(c) The unit has been exposed to rain; or(d) The unit does not operate normally or exhibits a marked changein performance; or(e) The unit has been dropped or the cabinet damaged.2.Servicing— Do not attempt to service the unit beyond that describedin these operating instructions. Refer all other servicing to authorizedservicing personnel.3.Replacement parts— When parts need replacing ensure the serviceruses parts specified by the manufacturer or parts that have the samecharacteristics as the original parts. Unauthorized substitutes mayresult in fire, electric shock, or other hazards.4.Safety check— After repairs or service, ask the servicer to performsafety checks to confirm that the unit is in proper working condition.4.Outdoor antenna grounding— If you connect an outdoor antenna,ground the antenna system to protect against voltage surges andbuilt-up static charges. Section 810 of the National Electrical Code,ANSI/NFPA No. 70-1990, provides information about grounding ofthe mast and supporting structure, grounding of the lead-in wire to anantenna discharge unit, size of grounding conductors, location ofantenna-discharge unit, connection to grounding electrodes, andrequirements for the grounding electrode.
