Power Off - Kenwood KC-207 Instruction Manual

A\caution : Read this page carefully to keep your safety.
11. Magnetic fields — Keep the units away from a
source of magnetic fields such as TV sets, speaker
systems, radios, motorized toys or magnetized ob-
jects.
12. Cleaning — Do not use volatile solvents such as
alcohol, paint thinner, gasoline, or benzine, etc. to
clean the cabinet. Use a clean dry cloth.

15. Damage requiring service — The unit should be
serviced by qualified service personnel when:
A. The power-supply cord or the plug has been
damaged; or
B. Objects have fallen, or liquid has been spilled
into the unit; or
C. The unit has been exposed to rain; or
D. The unit does not appear to operate normally or
exhibits a marked change in performance; or
E. The unit has been dropped, or the enclosure
damaged.
16. Servicing — The user should not attempt to ser-
vice the unit beyond that described in the operating
instructions. All other servicing should be referred
to qualified service personnel.
17. Outdoor antenna grounding — [If an outside
antenna is connected to the receiver, be sure the
antenna system is grounded so as to provide some
protection against voltage surges and built up
static charges. Section 810 of the National Elec-
trical Code, ANSI/ NFPA No. 70—1984, provides
information with respect 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 elec-
trodes, and requirements for the grounding, elec-
trode. See Figure.
®Use No. 10 AWG (5.3 mm?) copper, No. 8 AWG (8.4 mm?) alu-
minum, No. 17 AWG (1.0 mm?) copper-clad steel or bronze wire, or
larger, as a ground wire.
®Secure antenna lead-in and ground wires to house with stand-off in-
sulators spaced from 4 — 6 feet (1.22 — 1.83 m) apart.
"Mount antenna discharge unit as close as possible to where lead-in
enters house.
4Use jumper wire not smaller than No. 6 AWG (13.3 mm?) copper, or
the equivalent, when a separate antenna-grounding electrode is used.
See NEC Section 810-21()).
