Sudden temperature changes, storage or opera-

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.

a metal or CrO tape.)

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?
