Displaytest
Aktivieren des Tests:
- Gerät ausschalten.
- Tasten "DMX" und "
!
" gedrückt halten und Gerät einschalten.
- Es werden jetzt nacheinander alle Segmente des Displays einge-
schaltet.
- Anschließend wird das interne EEPROM getestet. Ist dieses in
Ordnung so zeigt das Display:
Dislpay Test
Activating the Test:
- Switch off the unit.
- Hold the buttons "DMX" and "
!
" depressed and switch on the unit.
- Now all segments in the display will be illuminated one after another.
- Now the internal EEPROM is being testet. If it is ok, the display
shows:

Hinweise
Der Schalter S701 auf der Hauptplatte muß eingeschaltet sein, da
sonst die Hauptplatte keine Betriebsspannung hat!
Notes
The switch S701 on the Main Board must be closed as otherwise
the Main Board has no power supply!
