Operation
After the distribution amplifi er 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 S 3
Sales and Technical Support Hotline.
