Furthermore, the manual outlines the procedure for accessing the service menu via the front-panel keypad. This hidden menu allows a technician to run diagnostic routines, display raw photometric counts, test individual motors, and view firmware versions. Crucially, the service manual contains the instructions for updating or reloading the instrument’s firmware, often via a serial or USB connection. It also provides the factory default calibration constants, which are essential if the onboard memory is lost or the main board is replaced.
