Operation
After the distribution amplifier and its connected devices are powered up, the system is fully operational. For further information, see Troubleshooting below.
Troubleshooting
Check all cable connections. If problems still exist, check the following steps:
1. | If the image on the laptop and/or projector is distorted or |
| unstable, do the following: |
| • Check if the front LED 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 laptop's VGA signal is routed to the VGA |
| port. Each laptop uses a different key combination for |
| this function. |
| • Slide DIP switch 2 to a different position and see if an |
| image appears. |
3. | If the image still does not display correctly, call Extron's S3 |
| Sales and Technical Support Hotline. |
