The entire Roland service manual for the A-90 controller is posted to
the files area of a different Yahoo group: Roland-Controllers
Once joined, look at the Files/Service Manuals directory.
In the service manual, you will see a description on how to replace
the backup battery. Recalibration of the pitch bend lever is required
after a battery change - all inside the manual.
