Troubleshooting

∫ Restoring factory default settings

If this unit does not operate properly, follow the

procedures below to restore it to the default settings that

it had when shipped new from the factory. Doing this

might correct the problem.

While the unit is on, press and hold the stop (∫) button

and press the Í ON/STANDBY button.

∫ Power/Remote control

The unit does not turn on.

0 Confirm that the power plug is securely plugged in to

an outlet.

0 Unplug the power cord once, wait five seconds and

then plug it in again.

“Now Initializing...” appears on the display.

0 If you turn on the unit when the input source is set to

USB or NET, it takes about 20 to 30 seconds until the

unit recognizes the input.

The unit turns off.

0 When the Auto Standby function is enabled, the unit

will enter standby automatically after a set amount of

time. See “ASb (Auto Standby)” under “Menu settings”

in “Various settings” to check the setting.

Remote control does not work.

0 Make sure the batteries have been installed with the

correct polarity (i/j).

0 If the batteries are exhausted, replace both of them

with new ones.

0 Point the remote control at the front panel of the unit

from a distance of less than about 5 m.

0 The remote control will not work if there is an

obstruction between it and the main unit. In this case,

try changing the position.

0 If a fluorescent light is near the unit, turn the light off.

0 The unit is located behind the glass doors of a audio

rack or cabinet.

∫ Audio

There’s no sound.

0 Make sure the correct input source is selected.

0 If “MUTING” is displayed on the display, press the

MUTING button to cancel muting.

0 Make sure the speakers are connected correctly.

0 Check all connections and correct as necessary.

0 While headphones are connected, the speakers output

no sound.

0 If the headphones do not output audio, contact failure

could be the cause. See the instruction manual for the

headphones.

There is noise.

The sound quality is not good.

0 Make sure that i/j of the speaker cables are

connected correctly. Connect the speaker placed on

the left hand side to the L terminal of the unit, and

connect the right speaker to the R terminal.

0 Make sure all audio connecting plugs are pushed in all

the way.

0 Place the unit as far away as possible from TVs and

other devices that have strong magnetism.

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

waves near the unit, such as a cellular phone that’s

being used to make a call, the unit may output noise.

0 The unit’s precision drive mechanism may emit a faint

hissing sound while reading discs during playback or

when searching for tracks. You may be able to hear

this noise in extremely quiet environments.

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

minutes after the unit has been turned on and had time

to warm up.

0 Using cable ties to bundle audio cables with speaker

or power cables may degrade the sound quality, so

don’t do it.

∫ CD playback

Playback is not possible.

0 If the disc is upside down, reload it with the labeled

side up.

0 If the disc is dirty, wipe it clean.

0 If a blank disc is loaded, replace it with a disc that has

recordings on it.

0 Depending on the quality of the disc and the condition

of the recording, playback of a CD-R/CD-RW might not

be possible.

0 This unit cannot play back unfinalized CD-R/CD-RW

discs.

The sound skips.

0 Vibrations will cause the sound to skip. Install this unit

in a stable location.

0 If the disc is dirty, wipe it clean.

0 Do not use discs that are scratched or cracked.

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.
