Moisture condensation
Moisture may condense on the lens inside the
system in the following cases:
• After turning on heating in the room.
• In a damp room.
• If the system is brought directly from a cold to
a warm place.
Should this occur, the system may malfunction.
In this case, leave the system turned on for a few
hours until the moisture evaporates, unplug the
AC power cord, and then plug it in again.
Cassette tapes
• If the tape is loose, it may get stretched, cut, or
caught in the cassette. Take up the slack by
inserting a pencil in one of the reels and
rotating.
• Do not touch the tape surface.
• Do not store the tape:
– In dusty places
– In direct sunlight or heat
– In moist areas
– On a TV or speaker
– Near a magnet
