Troubleshooting

Before starting the procedure

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. If the problem isn't fixed after

referring to "Troubleshooting", resetting the unit to the

status at the time of shipment may solve the problem. Note

that your settings will also be initialized when you reset, so

we recommend that you note down your settings before

doing the following.

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.

If operation becomes unstable

Try unplugging the power cord of the unit and connected

devices, and then plugging them in again.

Resetting the unit (this resets the unit settings to the

default)

If the issue is not fixed by unplugging the power cord,

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

solve the problem. Your settings will also be initialized when

you reset, so note down your settings before doing the

following.

1. While holding down SPEAKER A/B on the main unit,

press Í ON/STANDBY.

2. The unit switches to standby and the settings are reset.

∫ Power

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 switches to standby when the

"AutoStandby" setting in the Setup menu functions.

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 "NG" is

displayed, 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.

∫ Audio

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 the MUTING indicator on the display flashes, press

MUTING on the remote controller to cancel muting.

0 While headphones are connected to the PHONES jack,

no sound is output from the speakers.

No sound from an other connected external device

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

the terminal to which the other external device is

connected.

0 Check the digital audio output setting on the connected

component. On some game consoles, such as those that

support DVD, the default setting is off.

0 Only PCM audio is supported for input through the

DIGITAL IN OPTICAL/COAXIAL jacks. Set the audio

output on the other external device to output PCM.

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 (P8).

Noise can be heard

0 Using cable ties to bundle analog audio cables, power

cord, 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.

∫ AM/FM broadcasting

Radio reception is poor or there is a lot of noise

0 Re-check the antenna connection.

0 Separate the antenna from speaker cables and the

power cord.

0 Move the unit away from your TV or PC.

0 Passing cars and airplanes can cause interference.

0 Concrete walls weaken radio signals.

0 Listen to the station in mono.

0 When listening to an AM station, operating the remote

controller may cause noise (North American models).

0 FM reception may become clearer if you use the antenna

jack on the wall used for the TV.
