18. 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 2 ) copper, No.8 AWG (8.4mm 2 ) alumi-
num, No.17 AWG (1.0mm 2 ) 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 70-1990 for information.
e. Use jumper wire not smaller than No.6 AWG 13.3mm 2 ) copper
or equivalent, when a separate antenna grounding electrode is
used.
14. Servicing—Do not attempt to service the AC adaptor yourself
as opening or removing covers may expose you to dangerous
voltage or other hazards. Refer all servicing to qualified service
personnel.
15. Damage Requiring Service—Unplug this product from the
wall outlet and refer servicing to qualified service personnel under
the following conditions:
a. When the AC adaptor cord or plug is damaged.
b. If the AC adaptor has been exposed to rain or water.
c. If the product does not operate normally by following the
operating instructions. Adjust only those controls that are covered
by the operating instructions. An improper adjustment may result
in damage and will often require extensive work by a qualified
technician to restore the product to its normal operation.
d. If the product has been dropped or the cabinet has been
damaged.
e. When the product exhibits a distinct change in performance—
this indicates a need for service.
16. 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, electric
shock or other hazards.
17. Safety Check—Upon completion of any service or repairs to
this product, ask the service technician to perform safety checks
