Troubleshooting

In case you experience any problem with this unit, please take the time to look through this chart and see if you can solve the problem yourself before you call your dealer.

General

No power

eCheck the connection to the AC power supply. Check and make sure the AC source is not a switched outlet and that, if it is, the switch is turned on. Make sure there is power to the AC outlet by plugging another item such as a lamp or fan.

ePress the POWER button of the main unit to turn it on.

Remote control doesn’t work.

ePress the POWER button of the main unit to turn it on. eIf the batteries are dead, change the batteries.

eUse remote control unit within the range (7m /23ft) and point at the front panel.

eClear obstacles between the remote control unit and the main unit.

eIf a strong light is near the unit, turn it off.

Other units with remote controls operate incorrectly.

eNote that other units with remote controls may operate incorrectly because of infrared light “overspill” when you operate the remote control unit.

There is no sound or only a very low-level sound is heard. eAdjust the volume by turning the VOLUME knob.

eSelect the proper source using the INPUT knob.

eCheck that the speakers and components are connected securely.

eCheck the operation of the connected component.

No sound from a Super Audio CD.

eDigital audio from a Super Audio CD cannot go through the OPTICAL or COAXIAL terminals. Use analog audio terminals (LINE IN).

No digital audio output.

eThe AI-10 isn’t equipped with Dolby Digital/DTS/MPEG decoders. The digital output setting of the connected player must be PCM. Or use analog audio terminals (LINE IN).

Unstable sound.

eSpeaker polarity (+/_) is reversed. Check all speakers for correct polarity.

Word Sync

The display shows “WRD ERROR!”

eThe connected unit may not be in word sync mode while the AI-10 is in word sync mode. Check the word sync terminal for correct connection and the settings on the connected unit.

eThe received digital signal doesn’t much the sync signal. Check the frequency of the word sync signal (see page 16).

eWhen you don’t use the WORD SYNC terminal, turn the word sync mode off (see page 13).

Buzzing noise produced at regular intervals.

eThe connected unit may not be in word sync mode while the AI-10 is in word sync mode. Check the word sync terminal for correct connection and the settings on the connected unit.

Normally, if this problem occurs, the display reads “WRD ERROR!”, but this message does not appear when deviation in sync is too small and out of the word error detection threshold of the AI-10.

i.LINK (AUDIO) terminal

The i.LINK (AUDIO) terminals will become available after a future hardware upgrade (charged).

No i.LINK output.	ENGLISH
eCheck the channel setting. One AI-10 unit must be set to
L/R channel when multiple AI-10 units are connected.
The i.LINK indicator blinks.
eTurn on the digital device connected to the i.LINK(AUDIO)
terminal. When you don’t use the i.LINK terminal, turn the
i_RC setting off.
If normal operation cannot be obtained, unplug the power
cord from the outlet and plug it again. This resets the
internal micro-computer which can be disturbed during
electrical storms, power interruptions, et cetera.

Short Circuit and Output Protection

“OVER LEVEL” blinks on the display when the short circuit protection (or the output protection) is activated. In this case, turn the unit off and check the speaker cables. The metal portions of the two separate wires should not touch.

If there is no shorted wire, turn down the volume using the VOLUME knob.

Thermal Overload Protection

“HIGH TEMP” blinks on the display when the overload protection is activated. In this case, turn the unit off and leave it for a few hours to cool it down.

Also check the location of your unit. Place the unit in a cool place, and always leave sufficient space around the unit for ventilation.
