THIS MUSIC SYSTEM IS CAPABLE OF RE
CEIVING THE NEW AM STEREO BROADCASTS

FROM THE AM BAND RADIO STATIONS.
HOWEVER LIKE MANY MUSIC SYSTEM CUR
RENTLY AVAILABLE ON THE MARKET IT WILL
REPRODUCE THIS AM STEREO SIGNAL ONLY
IN AM MONO, WHICH, IN EFFECT, IS OF NO
LESSER QUALITY THAN YOUR EXISTING AM
MONO MUSIC SYSTEM.

Suggestions for Safety

■ Use a standard AC wall outlet

1. Use from an AC power source of high voltage, such as that

used for an air conditioner, is very dangerous.

A fire might be caused by such a connection.

2. A DC power source cannot be used.

Be sure to check the power source carefully, especially on a
ship or other place where DC is used.

■ Grasp the plug when disconnecting the power supply cord

1. Wet hands are dangerous.

A dangerous electric shock may result if the plug is touched by
wet hands.

2. Never place heavy items on top of the power supply cord,

nor force it to bend sharply.

■ Place the unit where it will be well ventilated

Place this unit at least 10 cm (4") away from wall surfaces, etc.

■ Avoid places such as the following:

In direct sunlight or in other places where the temperature is
high.
In places where there is excessive vibration or humidity.

Such conditions might damage the cabinet and/or other component
parts and thereby shorten the unit’s service life.

■ Be sure to place the unit on a flat, level surface

If the surface is inclined, a malfunction may result.

■ Never attempt to repair nor reconstruct this unit

A serious electric shock might occur if this unit is repaired, dis
assembled or reconstructed by unauthorized persons, or if the

internal parts are accidentally touched.

■ Take particular care if children are present

Never permit children to put anything, especially metal, inside this
unit. A serious electric shock or malfunction could occur if articles
such as coins, needles, screwdrivers, etc. are inserted through the
ventilation holes, etc. of this unit.

■ If water Is spilled on the unit

Be extremely careful if water is spilled on the unit, because a fire or
serious electric shock might occur. Immediately disconnect the
power cord plug, and consult with your dealer.

■ Avoid spray-type insecticides

Insecticides might cause cracks or "cloudiness" in the cabinet and

plastic parts of this unit. The gas used in such sprays might,

moreover, be ignited suddenly.

■ Never use alcohol or paint thinner

These and similar chemicals should never be used, because they

might cause flaking or cloudiness of the cabinet finish.

■ Disconnect the power supply cord if the unit will not be used for a long time

If the unit is left for a long time with the power ON, this not only will
shorten its useful operation life, but also may cause other trouble.

■ If trouble occurs

If, during operation, the sound is interrupted or indicators no longer
illuminate, or if an abnormal odour or smoke is detected, imme
diately disconnect the power cord plug, and contact with your
dealer or an Authorized Service Center.

For United Kingdom

("EB” area code model only)

The "EB" indication is shown on the serial number tag.

Important

THE WIRES IN THIS MAINS LEAD ARE COLOURED IN ACCOR
DANCE 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 proceed as follows. The wire which is coloured BLUE
must be connected to the terminal which is marked with the letter N
or coloured BLACK.
The wire which is coloured BROWN must be connected to the
terminal which is marked with the letter L or coloured RED.
Under no circumstances must either of the above wires be con
nected to the earth terminal of a three pin plug.

Concerning the Remote Control

Battery installation

1 open the cover

Press gently and slide the cover out.

2

Insert the batteries included with this system.

•When you need to replace these batteries, use two UM-4
‘‘AAA’’, lEC R03 (1.5 V) or equivalent batteries.

Use of batteries

• Do not mix old and new batteries or batteries of different types
(carbon and alkaline, etc.).

•The average battery life is about one year. Although the battery
life varies depending on how often the device is used, you should
generally replace the batteries about once a year.

•Replace the batteries if commands from the remote control trans
mitter do not operate the unit even when the transmitter is held
close to the front panel.

•Never subject batteries to excessive heat or flame; do not attempt
to disassemble them; and be sure they are not short-circuited.

•If you will not be using the remote control for a long period of time,
remove the batteries and store them in a cool, dark place.

Operation notes

•Be sure that you insert the batteries so that their positive (+)
and negative (-) polarities match the polarities indicated in
the compartment. Batteries installed incorrectly may leak
and cause damage.

• Refer to “Use of batteries” for additional information,

3

Close the cover.

•If a battery teaks, remove all batteries and dispose of them prop
erly. Thoroughly clean the battery compartment before inserting
new batteries.
If the leaking electrolyte comes into contact with skin or clothes,
flush with water immediately.

•Keep batteries out of the reach of children.

• Do not use rechargeable-type (nickel-cadmium) batteries.

•Do not attempt to recharge alkaline or carbon batteries.

•Always remove old, weak, or worn-out batteries promptly and

dispose of them properly.

• Do not dispose of used batteries in household rubbish.

Aim the remote control transmission window toward the amplifier's
sensor. Avoid any obstacles.

• Use the remote control within a 60-degree angle of the amplifier.

•The reachable distance is within 6 meters directly facing toward
the amplifier.

•Be sure the transmission window and the amplifier's sensor are
free from dust. Excessive dust might prevent reception.

• If direct sunlight or other strong light source strikes the remote
control signal sensor part of the amplifier, it may impair the remote
control’s operation. If there is a problem, place the amplifier away
from the light source.

• If this system is installed in a rack with glass doors, the glass

doors' thickness or color might make it necessary to use the
remote-control transmitter a shorter distance from the system.
