Deterioration in the conductive
coating inside the case
The inside of the case is coated with a conductive material. If the
board undergoes repeated detaching/attaching, the coating on the
boss may deteriorate.
If the resistance value between the case center and the head of the
boss becomes 5Ω or more, the effect of conductive coating cannot
be expected. In such a case, replace the case.
Note : Consider about the natural environment carefully before through the old lithium battery away when you exchange to the new one.you exchange to the new one.

USER DATA SAVE AND LOAD
To save the data stored in the RAM of the mainframe (DR-770) in
an external memory or load external MIDI.
Methods of transmitting and receiving data are explained below.
NOTE : If loading is executed all data stored in the RAM of the
mainframe will be lost.
NOTE : If you select “ALL” and execute the Bulk Dump, the
memory on the receive device will be full before the Bulk Dump is
completed, not being able to receive any more data.
If this happens, change the data to be transferd to “SEQ,”“GLOBAL,”“DRMKITS,” or “1DRMKIT,” then execute the Bulk
Dump again.
注 意:ALLを選んでバルク・ダンプを実行した場合、
受信側の機器のメモリーが途中でいっぱいになり、それ以降
のデータを受け付けなくなることがあります。
このようなときは、転送するデータをSE Q、G L OB A L、
