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

Suggestions for Safety
Use astandard AC wall outlet
1. Use from an AC power source of high voltage, such as that
used for an air conditioner, is very dangerous.
Afire might be caused by such aconnection.
2. ADC 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.
Adangerous 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 aflat, level surface
If the surface is inclined, amalfunction may result.
Never attempt to repair nor reconstruct this
unit
Aserious 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. Aserious 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 afire 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 along 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 Lor coloured RED.
Under no circumstances must either of the above wires be con-
nected to the earth terminal of athree pin plug.

Concerning the Remote Control
Battery installation
1Open the cover
Press gently and slide the cover out.
2Insert the batteries included with this system.
•When you need to replace these batteries, use two UM-4
"AAA", IEC R03 (1 .5 V) or equivalent batteries.
•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.
3Close the cover.
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 ayear.
•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 along period of time,
remove the batteries and store them in acool, dark place.
•If abattery leaks, 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.
Operation notes
Aim the remote control transmission window toward the amplifier's
sensor. Avoid any obstacles.

Amplifier
dust Avoid dust
•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 aproblem, place the amplifier away
from the light source.
•If this system is installed in arack with glass doors, the glass
doors' thickness or color might make it necessary to use the
remote-control transmitter ashorter distance from the system.
•Use the remote control within a60-degree angle of the amplifier.
The reachable distance is within 6meters directly facing toward
the amplifier.

Connections
Connect the FM indoor antenna provided with
this system.
Tack or tape this antenna to awall. If you use a tack, be sure
it does not contact the internal antenna wire. Experiment with
the height and direction of the antenna until you achieve the
best reception.
For best reception and sound quality:
Use an FM outdoor antenna. If you use an FM outdoor an-
tenna, disconnect the indoor antenna.
