Camera troubleshooting overview
Camera troubleshooting is broken down into 2 parts, Phoenix automatic checks and Manual Checks. The main
purpose of the Phoenix automatic check is to try and identify the fault automatically without any manual
checks. If the Phoenix automatic flow is not providing enough information, manual checking can be
performed to narrow down the fault.
