Sudden temperature changes, storage or
operation in an extremely humid environ-
ment may cause condensation inside the
cabinet (CD pickup, MD pickup, etc.) or on
the transmitter on the remote control.
Condensation can cause the unit to mal-
function. If this happens, leave the power on
with no disc in the unit until normal playback
is possible (about 1 hour). Wipe off any con-
densation on the transmitter with a soft cloth
before operating the unit.
