TO PREVENT THE RISK OF ELECTRIC SHOCK, DO

NOT REMOVE COVER (OR BACK). NO USER-

SERVICEABLE PARTS INSIDE. REFER SERVICING TO

QUALIFIED SERVICE PERSONNEL.

WARNING

TO PREVENT THE RISK OF ELECTRIC SHOCK, DO NOT REMOVE

COVER (OR BACK). NO USER-SERVICEABLE PARTS INSIDE.

REFER SERVICING TO QUALIFIED SERVICE PERSONNEL.

This equipment is not waterproof. To prevent a fire or shock hazard, do

not place any container filled with liquid near this equipment (such as a

vase or flower pot) or expose it to dripping, splashing, rain or moisture.

To prevent a fire hazard, do not place any naked flame sources (such as

a lighted candle) on the equipment.

Store small parts out of the reach of children and infants. If accidentally

swallowed, contact a doctor immediately.

Slots and openings in the cabinet are provided for ventilation to ensure

reliable operation of the product, and to protect it from overheating. To

prevent fire hazard, the openings should never be blocked or covered

with items (such as newspapers, tablecloths, curtains) or by operating

the equipment on thick carpet or a bed.

Do not use or store batteries in direct sunlight or other excessively hot

place, such as inside a car or near a heater. This can cause batteries to

leak, overheat, explode or catch fire. It can also reduce the life or

performance of batteries.

Risk of explosion if battery is replaced by an incorrect type. Risk of

explosion If disposal of a battery into fire or a hot oven, or mechanically

crushing or cutting of a battery.

Precautions

If you install the apparatus in a built-in installation, such as a bookcase or

rack, ensure that there is adequate ventilation.

Leave 20 cm (8”) of free space at the top and sides and 10 cm (4”) at the

rear. The rear edge of the shelf or board above the apparatus shall be

set 10 cm (4”) away from the rear panel or wall, creating a flue-like gap

for warm air to escape.

Operating Environment

Operating environment temperature and humidity: +5 °C to +35 °C (+41

°F to +95 °F); less than 85 %RH (cooling vents not blocked)

Do not install this unit in a poorly ventilated area, or in locations exposed

Important Notice

The model number and serial number of this equipment are on the rear

or bottom. Record these numbers on your enclosed warranty card and

keep in a safe place for future reference.

CAUTION

The power switch on this unit will not completely shut off all power from

the AC outlet. Since the power cord serves as the main disconnect

device for the unit, you will need to unplug it from the AC outlet to shut

down all power. Therefore, make sure the unit has been installed so that

the power cord can be easily unplugged from the AC outlet in case of an

accident. To avoid fire hazard, the power cord should also be unplugged

from the AC outlet when left unused for a long period of time (for

example, when on vacation).

The Safety of Your Ears is in Your Hands

Get the most out of your equipment by playing it at a safe level - a level

that lets the sound come through clearly without annoying blaring or

distortion and, most importantly, without affecting your sensitive hearing.

Sound can be deceiving. Over time, your hearing “comfort level” adapts

to higher volumes of sound, so what sounds “normal” can actually be

loud and harmful to your hearing. Guard against this by setting your

equipment at a safe level BEFORE your hearing adapts.

Be Sure To Observe The Following Guidelines:

0 Do not turn up the volume so high that you can’t hear what’s around

you.

0 Use caution or temporarily discontinue use in potentially hazardous

situations.

0 Do not use headphones while operating a motorized vehicle; the use

of headphones may create a traffic hazard and is illegal in many

areas.

Establish a Safe Level:

0 Set your volume control at a low setting.

0 Slowly increase the sound until you can hear it comfortably and

clearly, without distortion.

0 Once you have established a comfortable sound level, set the dial

and leave it there.

When disposing of used batteries, please comply with governmental

regulations or environmental public institution’s rules that apply in your

country/area.

Problems may be solved by simply turning the power on/off

or disconnecting/connecting the power cord, which is easier

than working on the connection, setting and operating

procedure. Try the simple measures on both the unit and the

connected device. After reconnecting, turn off and on the

unit and the connected device.

0 This unit contains a microPC for signal processing and

control functions. In very rare situations, severe

interference, noise from an external source, or static

electricity may cause it to lockup. In the unlikely event that

this happens, unplug the power cord from the wall outlet,

wait at least 5 seconds, and then plug it back in.

0 We are not responsible for reparations for damages (such

as CD rental fees) due to unsuccessful recordings caused

by the unit’s malfunction. Before you record important

data, make sure that the material will be recorded

correctly.

∫ Resetting the unit (this resets the unit settings

to the default)

Resetting the unit to the status at the time of shipment may

solve the problem. If the unit is reset, your settings are

restored to the default values. Be sure to note down your

setting contents before performing the following operations.

1. While the power is on, press Í ON/STANDBY while

pressing DIRECT.

∫ Cannot turn on the unit

0 Make sure that the power cord is properly plugged into

the wall outlet.

0 Unplug the power cord from the wall outlet, wait 5

seconds or more, then plug it in again.

∫ The unit turns off unexpectedly

0 The unit automatically enters standby mode when auto

standby (p19) is activated.

0 A speaker cable may have shorted and the protective

circuit function may have been activated. Make sure bare

speaker wires are not touching each other or the back

panel of the unit, then turn the unit on again. If this unit

does not turn on, immediately unplug the power cord from

the wall outlet and contact your dealer.

0 The protective circuit function may have been activated

because the temperature of the unit rose abnormally. If

this happens, then the power will continue to turn off after

you have turned the unit on again. Make sure the unit has

plenty of space for ventilation around it, wait for the unit to

cool down sufficiently, and then try turning it on again.

WARNING: If smoke, smell or abnormal noise is produced

by the unit, unplug the power cord from the wall outlet

immediately and contact the dealer or customer support.

0 Confirm that the connection between the output jack on

the device and the input jack on this unit is correct.

0 Make sure that none of the connecting cables are bent,

twisted, or damaged.

0 If MUTING is active, press MUTING on the remote

controller to cancel. MUTING is active when the indicator

for the selected input source is blinking.

0 While headphones are connected to the PHONES jack,

no sound is output from the speakers or subwoofer.

∫ Audio performance

0 Audio performance will be at its best about 10 to 30

minutes after the integrated amplifier has been turned on

and had time to warm up.

0 The sound quality can be affected by strong magnetic

fields, such as those from a TV. Try moving any such

devices away from the integrated amplifier.

0 If you have any devices that emit high-intensity radio

waves near the integrated amplifier, such as a cellular

phone that’s being used to make a call, the integrated

amplifier may output noise.

0 Install the integrated amplifier on a sturdy rack or shelf.

Position it so that its weight is evenly dispersed on its four

insulators. Do not install the integrated amplifier in a place

with vibration or an unstable location.

∫ No sound from a connected playback device

0 Change the input selector on this unit to the position of

the terminal to which the playback device is connected.

∫ A speaker produces no sound

0 Make sure that the polarity of the speaker cables (+/-) is

correct, and that no bare wires are in contact with the

metal part of speaker terminals.

0 Make sure that the speaker cables have not shorted.

0 Make sure the speakers are connected correctly. (p9)

∫ Noise can be heard

0 Using cable ties to bundle analog audio cables, power

cords, speaker cables, etc. may degrade the audio

performance. Do not bundle cords.

0 An audio cable may be picking up interference. Try

repositioning your cables.
