11 GROUNDING OR POLARIZATION
This unit is equipped with a polarized alternating -current line plug (a plug having one blade wider than the other).
This plug will fit into the power 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 the plug still fails to fit, contact your electrician to replace your obsolete
outlet.To prevent electric shock, do not use this polarized plug with an extension cord, receptacle, or other outlet
unless the blades can be fully inserted without blade exposure. If you need an extension cord, use a polarized
cord.
12 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 unit.
Note to CATV system installer
This reminder is provided to call the CATV system installer’s attention to Section 820-40 of the NEC which
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.
13 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 as to provide some
protection against voltage surges and built-up static charges. Section
810 of the National Electrical Code, ANSI/NFPA No. 70-1984
(Section 54 of Canadian Electrical Code, Part 1) provides information
with respect to proper grounding of the mast and supporting
structure, grounding of the lead-in wire to an antenna-discharge unit,
connection to grounding electrodes, and requirements for the
grounding electrode. See example as shown.
14 Power Lines
An outside antenna system should not be located in the vicinity of overhead power lines, 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 or approaching such power lines or circuits as contact with
them might be fatal. Installing an outdoor antenna can be hazardous and should be left to a professional antenna
installer.
15 LIGHTNING
For added protection for this unit during a lightning storm, or when it is left unattended and unused for long periods
of time, unplug it from the wall outlet and disconnect the antenna or cable system. This will prevent damage to
the unit due to lightning and power line surges.
16 DISC TRAY
Keep your fingers well clear of the disc as it is closing. It may cause serious personal injury.
17 OVERLOADING
Do not overload wall outlets of extension cords as this can result in a risk of fire or electric shock.
18 OBJECT AND LIQUID ENTRY
Never push objects of any kind into this unit through openings as they may touch dangerous voltage points or
“short-out” parts that could result in a fire or electric shock. Never spill liquid of any kind on the unit.
19 BURDEN
Do not place a heavy object on or step on the product. The object may fall, causing serious personal injury and
serious damage to the product.
20 DISC
Do not use a cracked, deformed or repaired disc. These discs are easily broken and may cause serious personal
injury and product malfunction.
