After the LEDs ßash, you will see the Main Diagnostic Display:
E.M. DIAGS V1.00
CONTROLS CPU
The number in the upper-right corner is both the Operating
System version and Diagnostics version. From this screen, you
have three choices:
• Press Exit to quit Diagnostics and enter Play mode.
• Press Controls (<) to enter the User Controls Diagnostic.
• Press CPU (>) to bring up CPU Diagnostics, which let you
access the MIDI test. (The other CPU tests are only for
authorized Kurzweil Service Technicians.)
User Controls Diagnostic
The User Controls Diagnostic lets you test the buttons, Ribbon,
and any other controllers that are plugged into the
ExpressionMate.
While on the Main Diagnostic Display screen, press Controls (<),
and youÕll see this screen:
BATT=OK RIBBON
EXIT/GLOBAL=EXIT
If the battery voltage is less than 2.5 volts, the display will read
ÒBATT=BAD.Ó If this happens, read the battery replacement
steps on page 105.
Start pressing the buttons or moving controllers that you want to
test. The display should change to show which control you are
using, as described on the next few pages.
You can exit the Diagnostic at any time by pressing the Exit and
Global buttons simultaneously. This takes you back to the Main
Diagnostic Display screen.
Buttons Test
When you press a button, the display changes to this:
BUTTON xx
