Condensation
Sudden temperature changes, storage or operation in an extremely

the transmitter on the remote control.

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.

(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.
