concept Before starting operation, please read this instruc¬
tion manual thoroughly and acquaint yourself with the
proper mode of using the unit and all its connections.
We hope you will enjoy top-notch performance for many
years to come.
INSTALLATION
Be sure to place the unit in a level and flat place where it
is free from humidity, vibration, high temperature and not to
place the unit in a highly enclosed place such as near a wall
or on a bookshelf. A poor ventilation will cause undesirable
effects to the unit.
POWER SUPPLY CONNECTION
For power the unit requires the normal house electrical cur¬
rent (AC). You may simply plug the unit into a wall outlet, or
into your amplifier's (or receiver's) convenience AC outlet.
CAUTION: Do not apply power without first making sure the
proper connections are completed. If you live in U K. and your
unit comes with 2-core cord without a plug, be sure to read
the exclusive caution for U K.
EXCLUSIVE NOTE FOR U.K.
If your unit comes with a 2-core cable without a plug,
make certain live and neutral leads are connected to the
proper terminals. Check that the terminals are screwed
down firmly and no loose strands of wire are present.
IMPORTANT: The wires in this mains lead are coloured
in accordance with the following code:
BLUE:
NEUTRAL
BROWN: LIVE
As the colours of the wires in the mains lead of this ap¬
paratus may not correspond with the coloured markings
identifying the terminals in your plug proceed as follows.
The wire which is coloured BLUE must be connected to
the terminal which is marked with he letter N or coloured
BLUE or BLACK. The wire which is coloured BROWN
must be connected to the terminal which is marked with
the letter L or coloured BROWN or RED.
CAUTION:
To prevent electric shock do not use this (polarized)
outlet unless the blades qan be fully inserted to prevent
blade exposure.
■ FM Antenna
Proper installation of antenna is the key to smooth signal
reception. To install the attached T-shape indoor antenna,
stretch it taut and secure horizontally along a wall or the like
in a location where signal reception is optimal. Securely
connect the antenna to FM antenna terminals marked "300fi"
on the rear panel if outdoor type FM antenna is installed, the
T-shape antenna is not necessary. For proper use of your
outdoor FM antenna, follow the instructions below.
1. Be sure to select the most appropriate type of antenna
for the signal reception conditions in your area.
2. A 75-ohm coaxial cable is recommended in connecting
the antenna to the unit.
3. Set the antenna in a position as high as possible if
buildings, mountains or other obstructions nearby affect
reception.
4. The 75-ohm coaxial antenna cable should be properly
hooked up to the designated antenna terminals on the rear
panel: Locate the terminals labeled "750"

■ AM Antenna
The loop antenna is provided for optimum AM reception.
Attach the loop antenna onto the antenna holder on the rear
panel, and connect the lead wires to the antenna screw ter¬
minals marked "G
and "AM". If an outdoor antenna is
desired for better reception due to difficult reception area,
connect such antenna to the same screw terminals as the
loop antenna. Please note that the loop antenna should be
left connected to the terminals even when the external
antenna is connected.
