Operating Considerations After Belt Replacement
After successful belt replacement, the Denon DRW-660 Dual Cassette Deck should operate as intended. Observe the following:
- Båndhastighed: Verify that playback and recording speeds are consistent and accurate.
- Wow og Flutter: Listen for any noticeable fluctuations in pitch (wow and flutter), which should be significantly reduced or eliminated with new belts.
- Transportfunktioner: Ensure all tape transport functions (Play, Record, Fast Forward, Rewind, Stop, Pause) engage smoothly and reliably.
If any issues persist, re-check the belt routing and ensure all connections are secure.
Opretholdelse
Proper maintenance extends the life of your cassette deck and its new belts.
- Regelmæssig rengøring: Periodically clean the tape heads, capstan, and pinch rollers with isopropyl alcohol to prevent tape residue buildup.
- Støvforebyggelse: Keep the cassette deck covered when not in use to prevent dust accumulation, which can affect mechanical parts and belt longevity.
- Bælteinspektion: While not easily accessible, if you notice performance degradation over time, the belts may need re-inspection or replacement again after many years of use.
