CAUTION:
Watch out for erroneous
measurements if the
instrument is defective or if it has
been dropped or has been misused
or modified.
Precautions:
Periodically carry out test
measurements and perform the field
adjustments indicated in the User
Manual particularly after the
instrument has been subjected to ab-
normal use and before and after
important measurements.
DANGER:
Because of the risk of
electrocution, it is very
dangerous to use reflector poles and
extensions in the vicinity of electrical
installations such as power cables or
electrical railways.
Precautions:
Keep at a safe distance from
electrical installations. If it is essential
to work in this environment, first
contact the safety authorities
responsible for the electrical
installations and follow their
instructions.

WARNING:
By surveying during a
thunderstorm you are at risk
from lightening.
Precautions:
Do not carry out field surveys during
thunderstorms.
CAUTION:
Be careful not to point the
instrument directly towards
the sun, because the telescope
functions as a magnifying lens and
can injure your eyes.
Precautions:
When viewing into the sun or against
bright objects only use suitable
accessories for this purpose.
