*You need to reinstall the program.
If the firmware update program is interrupted (for example, by a power failure), keep the SD
card inserted and turn the mains switch off and on. The firmware update program restarts. If you
do not do so, the message "Reboot after Card insert" is displayed when you turn the main
switch on.
