Safety Directions 5

WARNING
Distraction/loss of attention
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 dan-
gers.
WARNING
Inadequate securing of the working site.
This 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
Not properly secured accessories.
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 sus-
tain 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.
WARNING
Lightning strike
If the product is used with accessories, for example masts, staffs, poles, you may increase the
risk of being struck by lightning.
Precautions:
▶Do not use the product in a thunderstorm.
6 Safety Directions

DANGER
Risk of being struck by lightning
If the product is used with accessories, for example on masts, staffs, poles, you may increase
the risk of being struck by lightning. Danger from high voltages also exists near power lines.
Lightning, voltage peaks, or the touching of power lines can cause damage, injury and death.
Precautions:
▶Do not use the product in a thunderstorm as you can increase the risk of being struck by
lightning.
▶Be sure to remain at a safe distance from electrical installations. Do not use the product
directly under or close to power lines. If it is essential to work in such an environment con-
tact the safety authorities responsible for electrical installations and follow their instruc-
tions.
▶If the product has to be permanently mounted in an exposed location, it is advisable to pro-
vide a lightning conductor system. A suggestion on how to design a lightning conductor for
the product is given below. Always follow the regulations in force in your country regarding
grounding antennas and masts. These installations must be carried out by an authorised
specialist.
▶To prevent damages due to indirect lightning strikes (voltage spikes) cables, for example
for antenna, power source or modem should be protected with appropriate protection ele-
ments, like a lightning arrester. These installations must be carried out by an authorised
specialist.
▶If there is a risk of a thunderstorm, or if the equipment is to remain unused and unatten-
ded for a long period, protect your product additionally by unplugging all systems compo-
nents and disconnecting all connecting cables and supply cables, for example, instrument -
antenna.
Suggestion for design of a lightning conductor for a GNSS system:
1.On non-metallic structures
Protection by air terminals is recommended. An air terminal is a pointed solid or tubular rod
of conducting material with proper mounting and connection to a conductor. The position of
four air terminals can be uniformly distributed around the antenna at a distance equal to
the height of the air terminal.
The air terminal diameter should be 12 mm for copper or 15 mm for aluminium. The height
of the air terminals should be 25 cm to 50 cm. All air terminals should be connected to the
down conductors. The diameter of the air terminal should be kept to a minimum to reduce
GNSS signal shading.
2.On metallic structures
Protection is as described for non-metallic structures, but the air terminals can be connec-
ted directly to the conducting structure without the need for down conductors.

CAUTION
Inappropriate mechanical influences to batteries
During the transport, shipping or disposal of batteries it is possible for inappropriate mechanical
influences to constitute a fire hazard.
Precautions:
▶Before shipping the product or disposing of it, discharge the batteries by running the prod-
uct until they are flat.
▶When transporting or shipping batteries, the person in charge of the product must ensure
that the applicable national and international rules and regulations are observed.
▶Before transportation or shipping contact your local passenger or freight transport com-
pany.
WARNING
Exposure of batteries to high mechanical stress, high ambient temperatures or immer-
sion into fluids
This can cause leakage, fire or explosion of the batteries.
Precautions:
▶Protect the batteries from mechanical influences and high ambient temperatures. Do not
drop or immerse batteries into fluids.
WARNING
Short circuit of battery terminals
If battery terminals are short circuited e.g. by coming in contact with jewellery, keys, metallised
paper or other metals, the battery can overheat and cause injury or fire, for example by storing
or transporting in pockets.
Precautions:
▶Make sure that the battery terminals do not come into contact with metallic objects.
WARNING
Incorrect fastening of the external antenna
Incorrect fastening of the external antenna to vehicles or transporters poses the risk of the
equipment being broken by mechanical influence, vibration or airstream. This may result in acci-
dent and physical injury.
Precautions:
▶Attach the external antenna professionally. The external antenna must be secured addition-
ally, for example by use of a safety cord. Ensure that the mounting device is correctly
mounted and able to carry the weight of the external antenna (>1 kg) safely.

CAUTION
Electromagnetic radiation due to improper connection of cables
If the product is operated with connecting cables attached at only one of their two ends, for
example external supply cables, interface cables, the permitted level of electromagnetic radia-
tion may be exceeded and the correct functioning of other products may be impaired.
Precautions:
▶While the product is in use, connecting cables, for example product to external battery,
product to computer, must be connected at both ends.
Use of product with radio or digital cellular phone devices:
WARNING
Electromagnetic fields can cause disturbances in other equipment, in installations, in medical
devices, for example pacemakers or hearing aids and in aircraft. It can also affect humans and
animals.
Precautions:
▶Although the product meets the strict regulations and standards which are in force in this
respect, GeoMax cannot completely exclude the possibility that other equipment can be dis-
turbed or that humans or animals can be affected.
•Do not operate the product with radio or digital cellular phone devices in the vicinity of
filling stations or chemical installations, or in other areas where an explosion hazard
exists.
•Do not operate the product with radio or digital cellular phone devices near to medical
equipment.

4 Operation
4.1 Guidelines for Correct Results with GNSS Surveys
Successful GNSS surveys require undisturbed satellite signal reception, especially at the instru-
ment which serves as a base. Set up the instrument in locations which are free of obstructions
such as trees, buildings or mountains.
For static surveys, the instrument must be kept perfectly steady throughout the whole occupa-
tion of a point. Place the instrument on a tripod or pillar.
Centre and level the instrument precisely over the marker.
