1.2 Important Notes
Prior to using the 3D Ground Navigator and its accessories, please read these operating instructions
carefully. These instructions give information on how to use the detector and potential sources where
precautions should be taken.
The 3D Ground Navigator and its accessories serve for the analysis, documentation and detection of sub-
surface anomalies and ground disturbances. The recorded data of the ground structure will be
transmitted to a PC to give a visual representation using our proprietary software program. Any
additional notes to the software should be observed. Please read the user manual of the software!
1.2.1 General Notes
Being an electronic device, the 3D Ground Navigator has to be treated with caution and treated with
care as with any electronic device. Any failure to observe the safety precautions given or any use for
purposes other than the ones it is designed for may result in damage or destruction of the processing
unit and/or its accessories or connected components.
The device has a built in anti-tampering module which will destroy the unit if it is improperly opened.
There are no end user serviceable parts on the inside of the unit.
1.2.2 Possible Health Hazards
If used properly this device normally does not pose any health hazards. According to current scientific
knowledge, the high-frequency signals are not harmful to the human body on account of their low power.
1.2.3 Surrounding Area
When moving this unit from a cold place to a warmer place, watch out for condensation. Do not
immediately operate the unit until any possible condensation could have evaporated. The unit is not
weather proof and water or condensation can destroy the unit.
Avoid strong magnetic fields, which may occur in places where there are large electric motors or
unshielded loudspeakers. Try to avoid using this equipment within 50 meters (150 ft) of this type of
equipment.
Metallic objects on the ground such as cans, tin, nails, screws or debris can influence your scan data and
present negative results regarding your scan data. Also it is a good habit to remove any metallic objects
off of your person like cellular telephones, keys, jewelry, etc... Do not wear steel toe boots.
