Updating the software

The software version is briefly shown in the display when you power on the Nord Electro/Electro 2. For
more information on how to update the software, visit http://www.clavia.se.
Known or common errors
Many of the errors that occur can be related to the improper use of the synthesizer. Before it can be
established that a hardware error has occurred, check the manual and the FAQ on www.clavia.se for
information. In some cases an error can be cured by updating the software. See www.clavia.se for more
information on how to update the software. If the possibility of a software error can be excluded, check
the following:
- Is the fuse blown? Many times the problem can be as simple as that. Also check the power rating on the
back panel to make sure that it complies with your country.
- Does all voltages appear on the power supply unit/main board? For information on where to measure
the different voltages, see the schematic.
- Is there a bad connection? Check all ribbon cables and connectors to see that they are fixed in their
respective positions.
- Is there a bad solder joint? A bad solder joint might be difficult to discover on surface mount
components, but should be easy to find on hole mount components like jacks and connectors.
- Are all components and connectors in good condition? Inspect the card to see if the problem can be
detected visually.
- In general, some types of errors that are hard to trace might be cured by cleaning the board with an
electronic cleaning solvent. Sometimes this can remove conductive debris that shorts out tightly spaced
component pins. It might also help to gently scratch the surface between component pins with a scalpel
or a similar fine tipped instrument in order to remove debris.
The above list is by no means complete, but it can give an indication on where the problem might be
located.
Input or output jacks not working
The Nord Electro is built with high quality components and the circuit boards are well protected in a steel
chassis to withstand physical strain. However, input and output jacks are exposed to possible damage, for
example when dropping the synth. If a jack is not working, check the EMI-filter for that jack too see that it
conducts. Use a multimeter or other appropriate equipment to measure conductance. Measure at the outer
ends of the EMI-filter. See the schematic for details on where to find the EMI-filter for each jack. Also
check for bad solder joints or cracks in the PCB.
Display shows 'E7'
This error code indicates that there are errors on the software in FLASH. The problem can be cured by
updating the software to the latest version. The software is uploaded via MIDI with an update program
that can be downloaded at www.clavia.se. Follow the instructions as displayed by the program. In some
cases, this might not cure the problem.
Some keys not working or one key trigs several notes
This problem is most likely to occur if circuits U5, U12 and U29 on the main board are faulty. Inspect
them visually to see if any of them seem to be in bad condition.
