If a background has not yet been taught in, the user can do this by pressing the
Teach
Background
button. The teach-in process lasts 1.4 seconds. Alternatively, the back‐
ground can be taught in by pressing the teach-in pushbutton on the device. In this case,
the teach-in process is not started until a time delay of 5 seconds has passed. This
makes it possible for people to leave the measuring range and not be incorrectly taught
in as background.
If a background is available, the scan view changes and the live information appears on
the right side of the working range.
A taught-in background is saved directly on the device and is automatically loaded
when the device is restarted.
