■ Condensation
Sudden temperature changes, storage or operation in an extremely humid environ-

transmitter on the remote control.
Condensation can cause the unit to malfunction.
If this happens, leave the power on with no disc in the unit until normal playback is
possible (about 1 hour). Wipe off any condensation on the transmitter with a soft
cloth before operating the unit.
