Important Information
10. Grounding or Polarization - This video product is equipped
with either a three prong plug for 110 VAC use or a two prong
flat blade 220 volt type plug. Each type is to be inserted into
only the type of receptacle for which they are specifically
designed. Do not cut off the round grounding pin of a three
prong plug in order to be able to fit into a two prong receptacle
as this could cause injury and will void the warranty.
11. Power Sources - This product should be operated only from
the type of power source indicated on the marking label. If you
are not sure of the type of power supplied to your home, consult
your appliance dealer or local power company.
12. Power Cord Protection - Power supply cords should be rout ed so they are not likely to be walked on or pinched by items
placed upon or against them. Pay particular attention to cords
and plugs, convenience receptacles, and the point where they
exit from the appliance.
13. Lightning - For added protection for this product during a
lightning storm, or when it is left unattended or unused for long
periods of time, the unit should be disconnected from power
source.
14. Power Lines - An outside antenna system should not be
located in the vicinity of overhead power lines, other electric
light or power circuits, 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 may be fatal.
15. Overloading - Do not overload wall outlets and extension cords
as this can result in risk of fire or electric shock.
16. Object and Liquid Entry - Never push objects of any kind into
this product through openings as they may touch dangerous volt age points or short-out parts that could result in a fire or electric
shock. Never spill liquid of any kind on the product.
17. Servicing - Do not attempt to service this product yourself as
opening or removing covers may expose you to dangerous volt age or other hazards. Refer all servicing to qualified service
personnel.
18. 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 instruction. Adjust only those controls that are
covered by the operating instructions. An improper adjust ment 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 the cabinet has been
damaged
f. When the product exhibits a distinct change in performance
this indicates a need for service.
19. Replacement Parts - When replacement parts are required, be
sure the service technician has used replacement parts speci
fied by the manufacturer or have the same characteristics as the
original parts. Unauthorized substitutes may result in fire, elec
tric shock or other hazards.
20. 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 conditions.
21. Outdoor Antenna Grounding - Before attempting to install this
product, be sure the antenna or cable system is grounded so as
to provide some protection against voltage surges and built-up
static charges.
a. Use No.10 AWG (5.3mm ) copper, No.8 AWG (8.4mm)
aluminum, No.7 AWG (10mm) copper-clad steel or
bronze wire or larger, as ground wire.
b. Secure antenna lead-in and ground wires to house
with standoff insulators spaced from 4 feet (1.22m) to 6 feet
(1.83m) apart.
c. Mount antenna discharge unit as close as possible to where
lead-in enters house.
d. A driven rod may be used as the grounding electrode where
other types of electrode systems do not exist. Refer to the
National Electrical Code, ANSI/NFPA 70-1984 for
information.
e. Use jumper wire not smaller than No.6 AWG (13.3mm)
copper or equivalent, when a separate antenna grounding
electrode is used.
NOTE TO THE CATV SYSTEM INSTALLER:
THIS REMINDER IS PROVIDED TO CALL THE CATV SYSTEM
INSTALLER’S ATTENTION TO ARTICLE 820 - 40 OF
THE NEC THAT 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.
