Hazards of Use
Watch out for erroneous measurement results if the product has been dropped or has
been misused, modified, stored for long periods or transported.
Precautions:
Periodically carry out test measurements and perform the field adjustments indicated
in the user manual, particularly after the product has been subjected to abnormal use
as well as before and after important measurements.
Because of the risk of electrocution, it is dangerous to use poles, levelling staffs 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 instal-
lations and follow their instructions.
Strong magnetic fields in the immediate vicinity (e.g. transformers, melting
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 func-
tions 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.
During dynamic applications, for example stakeout procedures there is a danger of
accidents occurring if the user does not pay attention to the environmental conditions
around, for example obstacles, excavations or traffic.
Precautions:
The person responsible for the product must make all users fully aware of the existing
dangers.
Inadequate securing of the working site can lead to dangerous situations, for example
in traffic, on building sites and at industrial installations.
Precautions:
Always ensure that the working site is adequately secured. Adhere to the regulations
governing safety, accident prevention and road traffic.
If the accessories used with the product are not properly secured and the product is
subjected to mechanical shock, for example blows or falling, the product may be
damaged or people can sustain injury.
Precautions:
When setting-up the product, make sure that the accessories are correctly adapted,
fitted, secured, and locked in position.
Avoid subjecting the product to mechanical stress.
