Indication of the alignment quality
Important information
NOTE
Once 3 blue alignment quality light emitting diodes light up, alignment is good and
availability is stable.
Please note that body parts or objects in the protective field (e.g., hand, tool, AR60
optional laser alignment aid) may impair the function of the alignment quality LEDs.
Remove all objects from the protective field to allow the alignment quality to be
assessed.
