1.5 Hazards of Use

CAUTION 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.

DANGER 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.

NOTICE 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.

CAUTION 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.

WARNING 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.

WARNING 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.

CAUTION 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.
