This is a perfect copy of the Service Manual, The quality is great. I am very
happy. Thank you
I PURHASED THIS PRODUCT BECAUSE I WAS HAVING PROBLEMS WITH MY CDR20 HARMAN KARDON RECORDER. WHICH I PURCHASED NEW 12 YEARS AGO. AFTER REVIEWING THE MANUAL, I WAS ABLE TO ADJUST THE TENSIONER IN THE SYSTEM. WORKS LIKE A CHAMP!.
SAVED ME AT LEAST 100.00 WHICH WAS WHAT A SERVICE REPAIR STATION WANTED. GREAT MANUAL EASY TO READ. SPECIALLY AFTER I PRINTED THE PAGES WHICH DEALT WITH MY RECORDER. THANKS A LOT!!!!!!!!
You can fully trust on this one!
All the schematics are very crear an in one piece per page

1-1-4. Capacitor for Data Backup
To store a setup data and a real-time clock, the large storage capacitor (3 Farad) is mounted on the CPU264A board. To charge the large storage capacitor sufficiently, turn on the power of DVS-7000A for more than about thirty minutes. The sufficiently charged large storage capacitor enables data to be stored for about one week in the normal temperature.
