TROUBLESHOOTING 

There are several things you can try before you call FastVision Technical Support for help: 

_____ Make sure the computer is plugged in.  Make sure the power source is on. 

_____ Go back over the hardware installation to make sure that the system is properly 

installed. 

_____ Go back over the software installation to make sure you have installed all 
 

necessary software. 

_____ Review your FastCamera Test Data CD to review correct camera   configuration.

 

_____ Run the user-diagnostics test for your computer main board to make sure  it’s 

working properly. 

_____ Insert the FastVision CD-ROM and check the various Release Notes to see if there 

is any information relevant to the problem you are experiencing. 

FASTVISION TECHNICAL SUPPORT
