„ Condensation
Sudden temperature changes, storage or operation

heads, etc.) or on the transmitter on the remote con-
trol.
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 condensation on the
transmitter with a soft cloth before operating the unit.

metal or CrO tape.)

dirty?

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?
