Safety Instructions - continued

å  

Do not block or cover slots and openings in the unit. These are provided for ventilation and protection from overheating.  Never place the 

unit near or over a radiator or heat register. Do not place the unit in an enclosure such as a cabinet without proper ventilation. Do not mount 

equipment in the rack space directly above or below the unit.

å  

Operate the unit using only the type of power source indicated on the marking label. Unplug the unit power cord by gripping the plug, not the 

cord.

å  

The unit is equipped with a three-wire ground-type plug. This plug will fit only into a ground-type power outlet. If you are unable to insert the 

plug into the outlet, contact an electrician to replace the outlet. Do not defeat the safety purpose of the ground-type plug.

å  

Route power supply cords so that they are not likely to be walked on or pinched by items placed upon or against them. Pay particular attention 

to cords at plugs, convenience receptacles, and the point where they exit from the unit.

å  

Be sure that the outdoor components of the antenna system are grounded in accordance with local, federal, and National Electrical Code (NEC) 

requirements. Pay special attention to NEC Sections 810 and 820.  See the example shown in the following diagram:

å 

 We strongly recommend using an outlet that contains surge suppression or ground fault protection. For added protection during a lightning 

storm, or when the unit is left unattended and unused for long periods of time, unplug it from the wall outlet and disconnect the lines between 

the unit and the antenna. This will prevent damage caused by lightning or power line surges.

å 

 Do not locate the antenna near overhead power lines or other electric light or power circuits, or where it can fall into such power lines or circuits. 

When installing the antenna, take extreme care to avoid touching such power lines or circuits, as contact with them can be fatal.

å 

Do not overload wall outlets or extension cords, as this can result in a risk of fire or electrical shock.

å 

 Never insert objects of any kind into the unit through openings, as the objects may touch dangerous voltage points or short out parts. This could 

cause fire or electrical shock.

å 

 Do not attempt to service the unit yourself, as opening or removing covers may expose you to dangerous voltage and will void the warranty. Refer 

all servicing to authorized service personnel.

å 

 Unplug the unit from the wall outlet and refer servicing to authorized service personnel whenever the following occurs:

 

 The power supply cord or plug is damaged;

 

 Liquid has been spilled, or objects have fallen into the unit;

 

 The unit has been exposed to rain or water;

 

 The unit has been dropped or the chassis has been damaged;

 

 The unit exhibits a distinct change in performance.

å 

 When replacement parts are required, ensure that the service technician uses replacement parts specified by Blonder Tongue. Unauthorized 

substitutions may damage the unit or cause electrical shock or fire, and will void the warranty.

å 

 Upon completion of any service or repair to the unit, ask the service technician to perform safety checks to ensure that the unit is in proper 

operating condition.
