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. 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 STANDBY/ON while

pressing DIRECT.

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 enters standby mode when auto

standby (p20) 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.

0 When switched to power amplifier mode, if the volume of

the connected pre-amplifier is low, auto standby (p20)

may function and the power may automatically switch to

standby. If this happens, you may be able to fix it by

increasing the volume on the pre-amplifier.

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 MUTE is active, press MUTE on the remote controller to

cancel. MUTE is active when the SPEAKERS indicator

and the indicator for the selected input source are

blinking.

0 While headphones are connected to the PHONES jack,

no sound is output from the speakers.

∫ 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.

0 Only PCM audio is supported for input through the

DIGITAL IN OPTICAL/COAXIAL jacks. Set the audio

output on the playback 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.
