BEFORE ENJOYMENT/
POWER SUPPLY

Follow the instructions below for maximum
safety: ,

1. Use a wall outlet for power supply

Be sure to connect the AC line cord directly to
a household wall outlet, and not to an auxiliary
outlet on another component. Be certain that
the outlet voltage matches the electrical rating
of the unit, found on the rear panel name plate.
2. Connecting and removing AC cord

Be sure to connect or disconnect the AC line
cord only after turning off the power switch to
prevent possible shock noise or damage to
the speakers.

3. Ventilete the unit well

Never block any ventilation holes at the top
and bottom of the unit. Be sure also to provide
ample ventilation space around the unit. Poor
ventilation may result in damage due to exces~
sive heat.

4. Do not open the cabinet

In order to avoid electric shock or damage to
the component, never open the cabinet. If a
foreign object falls inside the unit by mistake,
turn the power off, disconnect the wall plug,
and consult a qualified electrician or your
dealer.

5. Installation

Be sure to place the unit in a level and flat place
where it is free from humidity, vibration, high
temperature and not exposed to direct sunlight.
Be careful not to place the unit in a highly
enclosed place such as near a wall or on a
bookshelf. A poor yentilation will cause unde-
sirable effects to the unit.

6. Moving the unit

When transporting, remove the AC cord from
the wall outlet and all other connected cards on
the rear panel to prevent wire breakage and
short circuits.

7. If the unit gets wet

If the unit should get wet, immediately discon-
1ect the AC cord, and consult your dealer or a
qualified electrician.

3. Cleaning and maintenance

Do not use chemicals such as benzine or thin-

ners on the front panel. Always use a soft, dry
cloth to clean the unit.

9. Owner's manual

Keep the owners manual near the unit, and
record the serial number (found on the rear
panel) on the cover.

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 follow-

ing code:
BLUE: NEUTRAL
BROWN: LIVE

As the Colours of the wires in the mains lead
of this apparatus 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 the 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 colour-
ed BROWN or RED.

SPEAKERS

The unit allows hookup of two speaker sys-
tems. Use speaker systems with impedance
ratings of 846 ohms. Before hooking up your
speaker system. be sure to check its impedance,
which should be indicated either on the back of
the speaker, or in the speaker instruction man-
ual.

of speaker terminals, "A" and "B", to which
two speaker systems may be connected. Con-

0 terminals R" Of A IOI HE), and the
speaker leads of the left-hand speaker to tern
minals "L" of A" (or "3"). Make sure that the
"+" speaker lead is connected to the "+" ter-
minal, and the -~" lead to the "-" terminal.
Strip 1.0cm (3/8) of the polyvinyl chloride
insulation from the end of each speaker lead.
Twist the exposed strands tightly, and secure
the end with a touch of solder.

The terminals are the push-insert type. Insert
