„ Condensation
Sudden temperature changes, storage or opera-

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.
Possible cause
z Is the erase-prevention tab removed?
z Is it a normal tape? (You cannot record on
a metal or CrO tape.)
z Is there any slack?
z Is the tape stretched?
z Are the capstans, pinch rollers, or heads
dirty?
z If a power failure occurs during playback,
the heads remain engaged with the tape.
Do not open the compartment forcibly.
Wait until electricity resumes.
Possible cause
z Is the AC power lead of the unit plugged
in?
z Is the battery polarity respected?
z Are the batteries dead?
z Is the distance or angle incorrect?
z Does the remote control sensor receive
strong light?
