Running the test program

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.
The functions provided by the test program allow a quick and easy search for possible
errors in the hardware.

Navigating through the test program
In order to execute the different tests on a Nord Lead 2/2X, first make sure power is
turned on. Press [ SHIFT + SYSTEM + SLOT X ] where X stands for one of the
following tests:
A: Knob test. Turn each knob fully counter clockwise, fully clockwise and then fully
counter clockwise again. A completely tested knob is indicated by a dot and a hyphen.
The knobs has to be turned in order, starting with the Master Level. Find the next knob
by first trying the one closest to the previous position. Exit the test with the [ PANIC ]
button. Reset the test with the [ DEMO ] button. If an error shows up, try performing
the simple knob test described in the next section.
B: Button test. Pressing each button should turn on the corresponding LED or LED
group. The buttons have to be pressed in order, starting with [ CLEAR ]. Find the next
knob by first trying the one closest to the previous position. Once a knob has been lit,
it cannot be switched off. Pressing all the buttons exits the test. You can also exit the
test manually by pressing the [ PANIC ] button.
C: Pitch stick calibration test. Tests that the pitch stick is calibrated. The value shown in
the display should be between 72 and 96. If the value is too small, this is indicated by
a dot. If the value is too large, this is indicated by a hyphen. Exit the test by pressing
the [ PANIC ] button.
D: Button and pitch stick test. This test differs from the tests above in a way that the
knobs do not have to be turned in any specific order. However, a knob must be fully
tested before the next one can be tested. This is done by turning a knob fully counter
clockwise, fully clockwise and then fully counter clockwise again.
A completely tested knob is indicated by a dot and a hyphen.
The pitch stick is tested by moving it fully to the left, then right and finally to the left
again. Hold the pitch stick in the leftmost position in order to continue testing another
function.
