Have been unable to enter service mode on my MZ-R700PC. Have tried many times - anyone got any ideas? Get flashing HOLD in display until I release the VOL- key, then display goes blank. (no release level info displayed) so R700 just remains in normal mode. Should there be a disk in the unit when trying the Service Mode sequence? I'm stumped!! It works if you key the sequence faster!! You get the new features as well. Thanks to Peter for his work on the eprom patches and sorry for wasting everyone's time.
