Suggestions for Safety
■ Use a standard AC wall outlet
1. Usa 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.
■ Ba sure to place the unit on a flat, level surface
If the surface is inclined, a malfunction may result.
■ Hever 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 igriited 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 disconrtect the power cord plug, and contact with your
dealer or an Authorized Service Center.

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.
•Reier to “Use o1 batteries” for additional information.
3 Close the cover.
•If a battery leaks, remove all batteries and dispose of them prop
erly. Thoroughly dean 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.

free from dust. Excessive dust might prevent reception.
•if direct sunlight or other strong light source strikes №e remote
controi signai sensor part of the ampiifier, 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 instailed in a rack with glass doors, the glass
doors' thickness or color might mdre it r>ecessary to use the
remote-control transmitter a shorter distance from the system.

Start the sound source.
4
Adjust the volunra level.
The memory backup function will retain the volume level and
sound source.
Note;
Before you set the system to the standby mode, be sure to reduce
the volume level to prevent the extremely high output from the
amplifier from damaging the speakers.
How to mute the volume
Press the MUTING on the remote control.
The muting indicator appears on the display.
•This lowers the volume level by 20 dB (approximately Vio).
•Cancel the muted state by pressing the muting button once again
or reduce the volume level to the minimum position and then reset
to the desired volume.
How to use headphones (not Included)
Reduce the VOLUME level.
Connect the headphones to the headphones jack.
•When you connect the headphones, the speakers will automati
cally cut off.
•Avoid listening for prolonged periods of time to prevent hearing
damage.
• Plug type: Stereo mini
How to use a microphone (not included)
(For areas except for Australia and New Zealand only:)
Reduce the VOLUME level.
Connect the microphone to the MIC Jack.
•You can control microphone volume using the MIC VOL control
within the volume levels of the main unit. Make sure to adjust the
main volume level using the VOLUME control to optimum posi
tion.
•If you hear strange noises (squealing or howling) during mixing,
change the direction of the mioophone or turn down the volume.
