Unpacking and Installation
Unpacking and Installation
Athough it is neither complicated to install nor difficult to operate your set, a few minutes of your time is
required to read this manual for a properly wired installation and becoming familiar with its many features
and how to use them. Please take a great care in unpacking your set and do not discard the carton and
other packing materials. They may be needed when moving your set and are required if it ever becomes
necessary to return your set for service. Never place the unit near radiators, in front of heating vents, in
excessively humid or dusty location to avoid early damage and for your years of quality use. Connect your
complementary components as illustrated in the following page.
RISK OF ELECTRIC SHOCK
DO NOT OPEN
CAUTION
CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK.
DO NOT REMOVE COVER (OR BACK).
NO USER-SERVICEABLE PARTS INSIDE.
REFER SERVICING TO QUALIFIED SERVICE PERSONNEL.
WARNING
To prevent fire or shock hazard, do not
expose the unit to rain or moisture.
This symbol is intended to alert the user to the
presence of uninsulated “dangerous voltage”
within the product’s enclosure that may be of suf-
ficient magnitude to constitute a risk of electric
shock to persons.
This symbol is intended to alert the user to the
presence of important operation and mainte-
nance (servicing) instructions in the literature
accompanying the appliance.
Caution: To prevent electric shock do not use this (polarized) plug
with an extension cord, receptacle or other outlet unless
the blades can be fully inserted to prevent blade expo-
sure.
Attentions: Pour prévenir les chocs électriques ne pas utiliser cette
fiche polarisée avec un prolongateur, une prise de
courant on une autre sortie de courant, sauf si les
lames peuvent étre insérées à fond sans en laisser
aucune partie à découvert.
* Do not install this apparatus in a confined space such as a book case or similar unit.
* The apparatus shall not be exposed to dripping or splashing and no objects filled with liquids, such as vases,

switch).
B. Press 4(memory switch) then select the desirable address when 13(address selector switch).
C. Present status of tuner will be memorized in selected address.
- Method 2
A. Select the frequency that you want to memorize by the UP/DOWN switch and press 4(memory
switch).
B. Press 4(memory switch)
C. Present status of tuner will be memorized in 1 address.
D. If A and B action repeat, present status of tuner will be memorized in next address.
11. PRESET/SCAN
When the switch is pressed one time, memorized broadcasting can be listening sequentially during five
seconds. (The status display at the Number 9 of LCD.)
12. MODE PRESET/TUNE
When you press the UP/DOWN switch,
MODE PRESET is increase and decrease by 1 channel.
MODE TUNE is increase and decrease by 1 step.

Application of The Antenna
Application of The Antenna
- FM RECEIVING ANTENNA
First of all, you have to connect FM antenna in the box. But, The electric wave of FM broadcasting is able to
weaken in the case of hills and valleys, around buildings and in iron-reinforced buildings.
- INSTALLATION OF ANTENNA EXCLUSIVELY FOR FM
Listening to the broadcasting, fix the antenna after deciding the location and the direction so that the recep-
tion may be optimized.
- INSTALLATION OF ANTENNA USING THE COAXIAL CABLE
Noisy reception may occur in built-up areas and factory sites as well as around power cables. This may be
the case even when an antenna is used exclusively for FM. In these regions, install the antenna using 75Ω
coaxial cable.
- INDOOR ANTENNA
In the regions where FM broadcasting is heard comparatively well due to the near distance to the station or
wooden structure, you can receive broadcasting of good quality by using T-type antenna.(using matching
trans: 300Ω/75Ω)
- AM LOOP ANTENNA
Tuning the electric wave of AM broadcasting, you have to connect AM loop antenna in the box.
Fix one end of AM loop antenna single cable to the AM terminal and the other end to GND.
- AM OUTDOOR ANTENNA
Install the vinyl-coated cable to an outdoor place if the AM reception is not good enough.

- THE FOLLOWING INSTRUCTIONS ARE FOR EXTERNAL ANTENNA INSTALLATION:
“Antenna System–This receiver, tuner or tuner-amplifier is intended for connection to an antenna system,
including outdoor antennas or community antenna television (CATV) systems, installed to provide some pro-
tection against voltage surges and built up static charges. Articles 810 and 820 of the National Electrical
Code, ANSI/NFPA 70–1984, provide information with respect to grounding of the mast and supporting
structure, the lead-in wire to an antenna discharge unit, and the coaxial cable system; and with respect to
the size of grounding conductors, location of antenna-discharge units, connection to grounding electrodes,
and the requirements for the grounding electrode. If an outside antenna is connected to the antenna termi-
nal of the tuner, be sure the antenna system is grounded in a manner similar to the accompanying Figure.”
(See Figure 67.1).
aUse No. 10 AWG (5.3 mm2) copper, No. 8 AWG (8.4 mm2) aluminum, No. 17 AWG (1.0 mm2)
copper-clad steel or bronze wire, or larger, as a ground wire.
bSecure antenna lead-in and ground wires to house with stand-off insulators spaced from 4–6 feet
(1.22–1.83m) apart.
cMount antenna discharge unit as close as possible to where lead-in enters house.
dUse jumper wire not smaller than No. 6 AWG (13.3 mm2) copper, or the equivalent, when a separate
antenna-grounding electrode is used. See NEC Section 810-21(f).
