NOTICE Strong magnetic fields in the immediate vicinity (e.g. transformers, melting
CAUTION
furnaces...) may influence the compensator and lead to measuring errors.
Precautions:
When working near strong magnetic fields, check results for plausibility.
Be careful when pointing the product towards the sun, because the telescope functions as a magnifying glass and can injure your eyes and/or cause damage inside the
product.
Precautions:
Do not point the product directly at the sun.
