Note To Catv System Installer - NAD M3 Owner's Manual

12 Grounding or Polarization - This product may be 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 should still fail to fit, contact your electrician to replace your obsolete outlet. Do not defeat the
safety purpose of the polarized plug.
13 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 product.
14 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. Article 810 of the National Electrical Code, ANSI/NFPA 70, provides
information with regard 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.

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.
15 Lightning - For added protection for this product 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 product due to lightning and power-line surges.
16 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.
17 Overloading - Do not overload wall outlets, extension cords, or integral convenience receptacles 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 product 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 product.
19 Damage Requiring Service - Unplug this product from the wall outlet and refer servicing to qualified service
personnel under the following conditions:
a) When the power-supply cord or plug is damaged.
b) If liquid has been spilled, or objects have fallen into the product.
c) If the product has been exposed to rain or water.
d) If the product does not operate normally by following the operating instructions. Adjust only those controls that
are covered by the operating instructions as an improper adjustment of other controls may result in damage
and will often require extensive work by a qualified technician to restore the product to its normal operation.
e) If the product has been dropped or damaged in any way.
f) when the product exhibits a distinct change in performance-this indicates a need for service.
20 Replacement Parts - When replacement parts are required, be sure the service technician has used replacement
parts specified by the manufacturer or have the same characteristics as the original part. Unauthorized substitutions
may result in fire, electric shock, or other hazards.
21 Safety Check - Upon completion of any service or repairs to this product, ask the service technician to perform
safety checks to determine that the product is in proper operating condition.
22 Wall or Ceiling Mounting - The product should be mounted to a wall or ceiling only as recommended by the
manufacturer.
