3.1.4.1 Proper Handling of Cassette Tapes

Digital Equipment Corporation recommends that you use TLZ04 cassette
tapes. To ensure optimal performance from your cassette tapes, observe
the following guidelines when handling them.
• Avoid placing the cassette tapes near sources of electromagnetic
interference, such as terminals, and video or X-ray equipment.
Emissions from such equipment can erase data on the tape.
• Keep cassette tapes out of direct sunlight and away from heaters and
other sources of heat.
• Store cassette tapes (and cleaning cassette) where the room
temperature is between 5°C and 32°C (40°F and 90°F).
• Store cassette tapes in a dust-free environment where the relative
humidity is 20% to 60%.
