The AOP-2 has a separate push-button (1) for the combined lamp test and dimmer functionality. A short acti-
vation of the push-button will activate the lamp test function. If no further action is taken within three seconds,
the AOP-2 will turn back to normal indication.
To activate the dimmer function, the push-button must be pressed several times or continuously to reach the
desired light intensity.
