Condensation

Sudden temperature changes, storage or operation in an extremely humid environment may cause condensation inside the cabinet or on the transmitter on the remote control.

Condensation can cause the speaker to malfunction. If this happens, leave the power on until normal operation is possible (about 1 hour). Wipe off any condensation on the transmitter with a soft cloth before operating the speaker.

If problem occurs

When this product is subjected to strong external interference (mechanical shock, excessive static electricity, abnormal supply voltage due to lightning, etc.) or if it is operated incorrectly, it may malfunction.

If such a problem occurs, do the following:

1.Set the speaker to the stand-by mode and turn the power on again.

2.If the speaker is not restored in the previous operation, unplug and plug in the speaker, and then turn the power on.

Factory reset, clearing all setting

Make sure to disconnect all audio input cables attached to the speaker before performing the factory reset.

Can be operated on the remote control only.

1.Press the ON/STAND-BY button to enter the power stand-by mode.
