Important safeguards
Please read all of the safety and operating
instructions before operating this unit. For best
results, follow all warnings placed on the unit and
‘adhere to the operating and use instructions. These
safety and operating instructions should be retained
for future reference.
1.
Power sources — The unit should be connect-
ed to a power supply only of the type described
in the operating instructions or as marked on the
appliance.
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. pay particular attention to cords
at plugs, convenience receptacles, and the point
where they exit from the unit.
Never pull or stretch
the cord.
Grounding or polarization — Precautions that
should be taken so that the grounding or polari-
zation means of this unit is not defeated.
. Ventilation — The unit should be situated so
that its location or position does not interfere
with its proper ventilation.
To maintain good ventilation, do not put records
or a table-cloth on the unit. Place the unit at least
10 cm away from the walls.
Do not use the unit on a bed, sofa, rug or similar
surface that may block the ventilation openings.
. Water and moisture — The unit should not be
used near water — for example, near a bathtub,
washbowil, kitchen sink, laundry tub, in a wet
basement, or near a swimming pool, etc.
A\ Caution: Read this page carefully to keep your safety.
6. Temperature — The unit may not: function
properly if used at extremely low. or freezing
temperatures. The ideal ambient temperature is
above +5°C (41°F).
. Heat - The unit should be situated away from
heat sources such as radiators, heat registers,
stoves, or other units (including amplifiers) that
produce heat.
. Electric shock — Care should be taken so that
10.
object do not fall and liquid are not spilled into
the enclosure through openings. If a metal
object, such as a hair pin or a needle, comes into
contact with the inside of this unit, a dangerous
electric shock may result. For families with
children, never permit children to put anything,
especially metal, inside this unit.
Enclosure removal — Never remove the enclo-
sure. If the internal parts are touched accidental-
ly, a serious electric shock might occur.
AC outlets - Do not connect other audio
equipment with a power consumption larger
than that specified to the AC outlet on the rear
panel. Never connect other electrical units, such
as an iron or toaster, to it to prevent fire or
electric shock.
The maximum capacities indicated for the AC
outlets on the rear panel of the this unit are as
follows.
1. SWITCHED outlets ; 7OOW
2. UNSWITCHED outlets ; 100W
KT-87 {K) 3

11. Magnetic fields - Keep the units away from
a source of magnetic fields such as TV sets,
speaker systems, radios, motorized toys or mag-
netized objects.
12. Cleaning — Do notuse volatile solvents such as
alcohol, paint thinner, gasoline, benzine, etc. to
clean the cabinet. Use a clean dry cloth.
13. Nonuse periods — The power cord of the unit
should be unplugged from the outlet when left
unused for a long period of time.
A\ Caution: Read this page-carefully to keep your safety.
14. Abnormal smell — If an abnormal smell or
smoke is detected, immediately turn the power
OFF and pull out the power cord. Contact your
dealer or nearest service station.
POWER OFF!

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.
15.
16. Servicing - The user should not attempt to
service 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
Electrical 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 electrodes, and requirements for
the grounding electrode. See Figure. —
2
Use No.10 AWG (5.3 mm?) copper, No.8 AWG (8.4 mm?)
aluminum, No.17 AWG (1.0 mm?) copper-clad steel or bronze wire,
or larger, as a ground wire.
o
Secure antenna lead-in and ground wires to house with stand-off
insulators 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.
4 Use 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 810-2 1(j).
18. Power lines — An outdoor antenna should be
located away from power lines.

Note:
Do not place the AM loop antenna on the unit. As this unit employs
computing device. placing the AM loop antenna on the unit may
result in noise generation. Place the AM loop antenna away from
the unit.
6 KT-87 {K)
AM outdoor antenna ;
In steel buildings or at a great distance from the transmitter,
it may be necessary to install an outside long wire antenna.
The end of this wire should be stripped of insulation and
connected to the AM terminal. At this time, keep the loop
antenna connected.
FM antenna
Your tuner approaches the theoretical limit in FM sensitivi-
ty. However, the performance of your system is determined
to a very large extent upon the signal conditions where the
antenna is placed. The reason is that FM broadcast signals
travel in straight paths. Therefore they can.be blocked by
natural or man-made obstructions such as mountains, hills
or buildings. At large distances from the transmitter the
curvature of the earth acts as a screen between the
transmitter and receiver.
Consider the signal conditions in planning your installation.
lf you live in or near an urban area the indoor antenna
(supplied) may serve your needs adequately. However, if
desired stations are weak due to natural obstructions, or
if you live in a building which is made of steel-reinforced
concrete (which acts as a shield) it may be necessary to
install a good outdoor antenna.
FM outdoor antenna
Consult with your dealer or service man. about the best
method of selecting and erecting an outdoor FM antenna.
The choice. of lead-in (feeder) wire is also important. The
flat ribbonshapped twin lead performs well electrically, is
cheaper and is somewhat easier to handle in routing
through windows and around rooms. Coaxial cable is more
expensive, does a much better job of minimizing inter-
fence, is less prone to the effects of weather and close-by
metal objects, and is nearly as good a signal conductor as
the ribbon type wire. The latter is particularly true of
foam-type coaxial cables. Coaxial cable is somewhat more
difficult to install at the point where the cable enters the
building. If coaxial cable is selected, make sure the antenna
is designed to drive that type of cable.
@ To minimize auto-ignition noise, locate the antenna as far from heavy
traffic as possible.
@ Keep the feeder or coaxial cable as short as possible. Do not bundie
or roll up excess cable.
@ The antenna should be at least two meters (6.6 feet) from reinforced
concerete walls, or metal structures.

Note:
Do not connect both the 300 feeder and 750 coaxial cable to
the FM antenna terminal.
