Built-In Self-Test Codes
The Built-In Self-test (BIST) codes are located in the Camera Information category under Power-on
Status. None of these should occur in a properly functioning camera except OVER_TEMPERATURE.
OVER_TEMPERATURE occurs if the ambient temperature is too high where there is insufficient air
circulation or heat sinking.

LED State
Description
Off
Camera not powerd up or waiting for the software to start
Constant Red
