BUILT-IN TEST
The AD1202 has a built-in test procedure that provides a
verification of AD1202 front panel controls.
To operate the built-in test:
1. Remove power from the AD1202, and remove the cover
from the unit.
2. Press the TEST button on the PCB while applying power to
the unit. See Figure A-1 for location of the TEST button.
Each of the front panel LED’s is illuminated in sequence.
This verifies that each LED illuminates properly.
If any LED’s do not illuminate, the unit is not operating
properly.
After the individual LED's have illuminated, continue with
the next step.
3. Press each front panel button, one at a time.
Each time a button is pressed, all ten front panel LED’s will
illuminate simultaneously, signifying that the switch closure
was recognized by the unit.
If the LED’s flash when a button is pressed, one or more
buttons may be shorted and the unit is not operating
properly.
4. Remove power from the unit to exit the test procedure.
If any of the above responses are not as indicated, the unit may
not be operating properly.
Note: An erroneous indication may be noted if the pan/tilt
keys are depressed incorrectly (the LEDs flash). Make
sure you press either one side or the other side of these
keys. Pressing these keys such that the two key switches
underneath are pressed simultaneously will result in
flashing LEDs.
