Appendix C. Troubleshooting
Observe the LED Operation
On normal power up the LED will slowly flash 4 times.
If the LED flashes rapidly for several seconds the camera failed one of the
power-on tests. In this case factory repair is necessary.
The LED will also flash once if the Setup button is pressed.
The LED will flash twice if the SNAP button is pressed.
During communication or a firmware update the LED will remain ON to
indicate a process is in progress that should not be interrupted.
If the power switch is in the ON position the LED should flash once every 5
seconds to indicate that it is running. If the setup button is pressed, the LED
will briefly flash once a second to indicate that the camera is ready for setup
using the Device Configuration Utility.
Power Connection
If power is applied to the camera and there is no LED activity, check the power
supply voltage, and the power supply connections.
Recheck Configuration
Recheck the method for obtaining the image. Reload the configuration files in
all devices used for the method selected.
Verify Switch Settings and Configuration
If using the snap button, is the camera switch in the “on” position?
If using a pulse, is the pulse long enough?
Are the configuration files correct for the mode desired?
