POWER SUPPLY

Follow the instructions below for
maximum safety:

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 ter»
minals are screwed down firmly
and no loose strands of wire are
present.

IMPORTANT: The wires in this
mains lead are coloured in ac-
cordance with the following
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 pro-
ceed 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 con-
nected to the terminal which is
marked with the letter L or
coloured BROWN or RED.

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. Power outlet on the rear panel
The rear panel of the unit is e-
quipped with a power supply outv
let designed exclusively for power-
ing the tuner FiT-400. Insert the
square plug of the RT-400 into the
power supply outlet. Never attempt
to insert any other plugs into this
outlet.

4. Installation

Be sure to place the unit on a level,
flat surface in a place free from hu-
midity, vibration, and high tempe-
rature and not exposed to direct
sunlight. Make sure the location

placed is well ventilated.

5. Vantilate the unit well

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

6. 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.

7. Turn the volume control initial-
ly to minimum.

When lowering the tonearm of your
turntable onto a record, an excess
of current in the lower frequency
range may cause damage to the
speakers. To prevent this, always
minimize the volume setting initial-
ly.

8. Moving the unit

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

9. If the unit gets wet

If the unit should get wet, immedi-
ately disconnect the AC cord, and
consult your dealer or a qualified
electrician.

10. Cleaning and maintenance

Do not use chemicals such as
benzine or thinners on the front
panel. Always use a soft, dry cloth
to clean the unit.

11. Retain the owners manual
Retain the owner's manual near the
unit, and write down the serial
number (found on the rear panel)
on the cover.

SPEAKERS

Be sure to use only speakers rated
at 4 7 16 ohms. The unit will ac-
cept two pairs of speaker systems,
but if the two systems are to be
driven at a time, each speaker
should be rated at 8 - 16 ohms.
The speaker impedance may be
found on its name plate or the
instruction manual of the speaker.
