operational. For further information, see “Troubleshooting” below.

Troubleshooting

• Check if the front LED of the P/2 DA2 Plus is lit.

• Slide DIP switch 1 to a different position to see if the image becomes normal.

2. If there is no image on the projector, do the following:

• Check if the front LED is lit.

• Check if the VGA signal from the laptop is routed to the VGA port. Each laptop uses a

different key combination for this function.

3. If the image still does not display correctly or the front panel LED of the P/2 DA2 Plus does

not light, call the Extron Sales and Support hotline.
