wrong distances,

sufficient space.

cialist.
Individual faulty pixels (light or dark pixels) are attributed to the module and not covered by
the warranty. They do not impair or reduce the functionality of the system.

Replacing the Fuse

The supply connection of the sensor unit has its own fine fuse for protection against overload.
Fuses must be replaced if the screen can no longer be switched on.
Proceed as follows to change the fuse:
Open the lid of the black "FUSE BOX" plastics box.
Replace the defective fuse with a new fuse of the same type and
nominal voltage.
Fine fuse 5 x 20 mm, 2 A delayed 250 V
Close the plastics box again carefully.
