Mechanism/cassette tapes
To avoid possible problems, you should not
use cassette tapes longer than 60 or 90
minutes (C60/C90). Store your tapes in a
cool place away from dirt, dust and
temperatures exceeding 50
°
Celsius. Allow
very cold tapes to warm up before playing
them in order to avoid uneven transport. After
approximately 100 hours of use, dust
particles collected on the playback head or
roller may lead to tape run problems and
sound distortions.
Use a head cleaning tape to remove normal
dirt build-up. For tougher cases, use a cotton
swab (Q-Tip) soaked with alcohol. Do not
attempt to clean by inserting a hard object
into the player!
