#73030 - 12/14/99 11:18 AM Yamaha DX7IIFD with E!card-backup batt.

Hi! My 1988 Yamaha DX7II with E! card has
probably lost its memories due to backup battery failure, either in the DX7 or the
E!card modules. On power.up it only displays
a lot of fffffffffffffff'S and plays no sounds, neither does it work as master keyboard to my other modules. I now have to
load the internal ERAM and Cartridge sounds from my floppy disk every time I want to play.
I have opened the bottom cover, but am unable to find the backup battery location and -type.
Can anyone help? How much do I have to dismantle?
Please reply by E-Mail to

Sincerely yours
Arvid Kaada, Sola, Norway.

See Dave Benson's DX7 Page; it also deals with the E!

Good Luck ,changing the battery appears to be quite a job. I'll have to do it on mine soon.mn
