Condensation
Sudden temperature changes, storage or operation in an extremely
humid environment may cause condensation inside the cabinet (CD
pickup, tape heads, etc.) or on the transmitter on the remote control.
Condensation can cause the unit to malfunction. If this happens,
leave the power on with no disc (or cassette) 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.
