Important Information!
Here is a brief background story.
Since the start of the Nord Stage line, Clavia has accurately picked and tested out the
best units from Fatar's semi weighted keybed production.
In order to increase the quality level on the velocity sensibility some hardware changes
were made to the main board and a calibration memory card was added to the keybed.
Due to this change, precaution has to be measured when replacing keybeds or main
boards at service.
Pls. see below for scenarios that may occur and how to handle the service matters.
Uncalibrated Units
Nord Stage 88 Serial No from SA10004 to SA11522
Nord Stage 76 Serial No from SB10001 to SB10182
Nord Stage Compact - There are no uncalibrated units
Scenario 1: Main board up to V1.2 needs to be replaced.
Action: Replace with main board (V1.2 or higher) AND a calibrated keybed (with
attached memory card).
Scenario 2: Keybed needs to be replaced.
Action: An approved but uncalibrated keybed must be used as replacement.
Calibrated Units
Nord Stage 88 Serial No from SA11523 and higher
Nord Stage 76 Serial No from SA10183 and higher
Nord Stage Compact Serial No from SA10001 and higher
Scenario 1: Main board must be replaced (V1.2 or higher)
Action: Replace with main board (V1.2 or higher)
Scenario 2: Keybed must be replaced.
Action: A calibrated keybed with memory card must be used as replacement.
In order to get the correct replacement parts, always state the units Serial No and also
the main board Version No that is printed on the barcode label.
NOTE! The small memory card attached to a calibrated keybed must be handled as a
unit and must during any circumstances NEVER be switched or removed from the
keybed. If a keybed must be scrapped, this card must go along with it.
