Condensation
Sudden temperature changes, storage or op-

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 conden-
sation on the transmitter with a soft cloth before
operating the unit.
