Page 21: Balancing The Cd Volume (Cd Master Balance)(Applies Only To Models With
Balancing the CD Volume (CD Master Balance)(Applies only to models with CD-ROM drives) Before playing back PianoSoft.PlusAudio and other audio/MIDI CDs, it is a good idea to first balance the volume levels of the MIDI piano and Audio parts. Once you adjust the volume using the CD Master Balance function, you can use the [VOLUME] buttons on the remote control to conveniently increase or decrease the overall volume in a normal fashion. -
Page 22: Maintenance
MAINTENANCE 1. Basic Approach As with previous hybrid models, the technician first adjusts the acoustic system, then adjusts the silent system (except for model DGA1, which does not have a silent system), and then lastly adjusts the elec- trical system using the built-in maintenance and test modes. Important Be sure to turn off the main power switch before removing the action or carrying out any other type of assembly. - Page 23 [MD-Unit Diagram and LED Table This adjustment is generally not required. Silent Off MD UNIT Green Green Silent On Green...
- Page 24 Adjusting the Regulating Rods Adjust the let-off as with a conventional acoustic piano. Set the Silent switch to On. Adjust the regulating-rod-lever adjustment screw so that the jack knob hits the rod about the same time that the jack tail hits the regulating button. Rotate the regulating-rod adjustment screws of each section to adjust the timing more precise.

Since the playback function of the solenoids (in particular, playback of very soft notes) degrades as the temperature increases, playback data is automatically compensated (when it is decreased, the data reverts to its original values).
