Internal care
• Dirty heads, capstans, and pinch rollers can cause poor sound and tape jams.
Clean these parts with a commercially available cleaning tape.
• After long use, the deck's heads and capstans may become magnetized, causing poor sound. Demagnetize these
parts once every 30 hours of playing/recording time by using a commercially available tape head demagnetizer.
Read the demagnetizer's instructions carefully before use.
