Sudden temperature changes, storage or opera-
tion in an extremely humid environment may
cause condensation inside the cabinet (CD pick-
up, 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 condensa-
tion on the transmitter with a soft cloth before op-
erating the unit.
