5.2 Error Codes

For certain errors that may occur in the Model 100 Projector the software provides
error codes that are helpful in determining the nature of the problem.
Note: Use a computer terminal connected to Port A or Port B for troubleshooting
because most error codes and messages will be displayed only on a terminal
screen. These error codes can be seen on the left side of the screen.
