Returning to factory settings
It is not possible to return to factory settings without connecting the Nord Electro to a computer. Once

Running the test program
The test program is stored in an EPROM located in position U17. If the version is older than 0.20, there is
no test program is available. To find out which EPROM version that is installed, the Nord Electro needs
to be opened.
In order to trace a hardware error easier, each Nord synthesizer has a test program. This program is
primarily used in production in order to test all functions. However, any user can access the test program
by holding down certain buttons at power up. The functions provided by the test program allow a quick
and easy search for possible errors in the hardware. Test results are shown on the Electro's display. If a test
is successful, the display reads "rd". If errors are detected, en error code is shown in the display. The error
codes are listed under the section "Error codes" at the end of this document.
