4.9 View and update the [Firmware] version, check serial number
Firmware is the underlying software installed on the gauge. To find out what version of the firmware is
installed, tap the [Firmware] key.
Figure 49: Gauge serial number and firmware version are shown on the third settings screen
The displayed white text indicates the firmware version first, then the serial number of the gauge after the
dash. A computer with Retrotec’s “DM32 Configurator” software installed is required to update the
firmware version on the gauge. For instructions, see Retrotec’s Manual-Software-DM32 Configurator.
4.10 Re-calibrate the touchscreen
The re-calibration process resets the internal mapping of the touchscreen to physical areas on the screen.
Re-calibration thus ensures the correct functions will be activated when a user touches the screen in the
area of the keys. Each display varies slightly so the touch screen is calibrated at the factory before being
sent out to the user, but can change over time. If you find that odd things are happening when you touch
an area of the screen, try re-calibration. You will need a stylus or some tool with a tip in order to tap with
the most precision on the re-calibration screens.
