13. Reliable Earthing: Reliable earthing of rack-mounted
equipment should be maintained. Particular attention should
be given to supply connections other than direct connections
to the branch circuit (e.g. use of power strips).
14. 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.
15. Power-cord Protection: Power-supply cords should be rout-

lightning storm, or when it is left unattended or unused for long
periods of time, the unit should be disconnected from power
source.
17. 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.
18. Object and Liquid Entry: Never push objects of any kind
into this product through openings as they may touch danger-
ous voltage points or short-out parts that could result in a fire or

specified by the manufacturer or have the same characteristics
as the original parts. Unauthorized substitutes may result in
fire, electric shock or other hazards.
22. 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.
23. 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 stand-off 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.
