System components
The connectors are plugged directly onto the conductor paths of the printed circuit board of the display and
operating unit. Some connections on the printed circuit board of the display and operating unit are not used.
The assignment can be determined by the imprint on the printed circuit board and the labelled tags on the
cables.
A button cell is located in the display and operating unit for camping equipment to buffer the time and date in
the event of a power failure. The button cell can be found directly on the printed circuit board. To change the
button cell, the housing cover must be removed.
If a software update is necessary, this can be done with an appropriate Micro-SD card.
The current software version can be read out in the Factory menu.
The Micro-SD card has a special formatting for the display and operating unit and cannot be read by
conventional means.
For more information about the update procedure, please refer to the current service literature!
