6. Flashing Firmware
To change the firmware of the device a separate Windows program (Flash Tool) is used. Before starting the
Flash Tool, any programs that access the key programmer, must be terminated.
Any firmware version can be copied to the key programmer, thus also downgrade the firmware is possible at
any time. The current firmware version of the LFSPG-MH can not be saved.
To Flash the firmware, the Flash Tool needs to be launched. The execution location is irrelevant. No
additional files are required.

With "Start", a file dialog is opened, so you can select the firmware file to Flash into the LFSPG-MH. The
Flash-process is started by pressing the Open button.
The top LED of the SPS lights blue for the duration of the operation.
