Condensation

Sudden temperature changes, storage or operation in an extremely humid environment may cause condensation inside the cabinet. Condensation can cause the unit to malfunction. If this happens, leave the power on until normal playback is possible (about 1 hour). Wipe off any condensation on the transmitter with a soft cloth before operating the unit.

If problem occurs during operation

When this product is subject 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 the unit is not restored in the previous operation, unplug and plug in the unit again

or

unplug all components connected and plug in again.

Maintenance

Cleaning the cabinet

Periodically wipe the cabinet with a soft cloth.

Caution:

Do not use chemicals for cleaning (gasoline, paint thinner, etc.). It may damage the cabinet finish.

Do not apply oil to the inside of each component. It may cause malfunctions.
