Guide to the Serial Copy Management System This digital audio tape deck adopts the Serial Copy Management System. This system enables one generation of digital recording of prerecorded software via digital input/output. A summary of this system is as follows: 1 You can record a compact disc to a digital audio tape via digital input/output. But you cannot record the recorded tape to another via digital input/output.
2 You can record a digital audio tape recorded via analog input/output to another via digital input/output. But, you cannot make a second generation tape via digital input/output.
Troubleshooting Guide Basic Operation Symptom Cause Remedy The tape is ejected after being loaded. The cassette is inserted incorrectly. Insert the cassette correctly.
