The module is stuck in the calibration routine, or one or several outputs

are not working

Check the jack connectors & Tactical plan soldering.

One or several LEDs are not working

Check the LEDs solder points and LED orientation.

Check the Tactical Plan headers solder points.

For the amber LEDs, check the PCB to PCB headers solder points on both

PCBs.

One or several potentiometers are not working

Check the solder points and Tactical Plan headers solder points

One or several buttons are not working

Check the buttons solder points.

Check the PCB to PCB headers solder points on both PCBs.

The 7 segment display is not working

Check the display solder points.

Check the PCB to PCB headers solder points on both PCBs.
