1.5 Hazards of Use
1.5.1 General
CAUTION
Dropping, misusing, modifying, storing the product for long periods or
transporting the product
Watch out for erroneous measurement results.
Precautions:
▶Periodically carry out test measurements and perform the field adjust-
ments indicated in the User Manual, particularly after the product has been
subjected to abnormal use as well as before and after important measure-
ments.

Person responsible
for the product
8 Safety Directions

WARNING
Distraction/loss of attention
During dynamic applications, for example stakeout procedures, there is a dan-
ger of accidents occurring if the user does not pay attention to the environ-
mental 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
The absence of a positive indication does not guarantee the non-existence of a
utility.
Utilities without a detectable signal may be present.
The locators can only locate non-metallic utilities such as plastic pipes, typically
used by the water and gas utilities, with the use of appropriate accessories.
Precautions:
▶Always excavate with care.
WARNING
Depth reading on locator might differ from actual depth of utility
When taking a depth reading, the depth is calculated as distance to the centre
of a utility or to a sonde within the utility. Depending on the diameter of a util-
ity, the depth reading might differ from the actual depth of the utility. This
specifically applies when the signal for depth estimation is produced by a
sonde lying in a large-diameter pipe or duct.
Precautions:
▶Always take into account allowances for the diameter of a utility.
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.
Safety Directions 9

CAUTION
Inappropriate mechanical influences to batteries
During the transport, shipping or disposal of batteries it is possible for inappro-
priate mechanical influences to constitute a fire hazard.
Precautions:
▶Before shipping the product or disposing of it, discharge the batteries by
running the product until they are flat.
▶When transporting or shipping batteries, the person in charge of the prod-
uct must ensure that the applicable national and international rules and
regulations are observed.
▶Before transportation or shipping contact your local passenger or freight
transport company.
WARNING
A hazardous signal can be present at the transmitter output when used in con-
nection mode and on the attached accessories and live utility itself.
Precautions:
▶Take care when handling exposed or non-insulated connections. Notify
others who may be working on or around the utility.
WARNING
Exposure of batteries to high mechanical stress, high ambient tempera-
tures or immersion into fluids
This can cause leakage, fire or explosion of the batteries.
Precautions:
▶Protect the batteries from mechanical influences and high ambient temper-
atures. 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 metal-
lic objects.

these products.
Safety Directions 11

1.5.2 Using the Product with a Signal Transmitter
DANGER
Clipping a transmitter clamp around a live utility
When a transmitter clamp is clipped around a live utility, a hazardous signal
might be present on the utility or at the transmitter plug connector, causing
you to receive an electric shock.
Precautions:
▶Do not clip a transmitter clamp around live utilities that have impaired or
no insulation.
▶Always ensure that the transmitter plug connector is connected to the
transmitter before you clip the transmitter clamp around a live utility.
DANGER
Connecting the cable set of the transmitter to a live utility
Connecting the cable set of the transmitter directly to a live utility can cause
you to receive an electric shock.
Precautions:
▶Never connect the cable set of the transmitter directly to a live electrical
utility.
DANGER
Power output of signal transmitter
The signal transmitter can output potentially lethal voltages!
Precautions:
▶Take care when using the maximum power output of the signal transmitter.
▶Take care when handling exposed or non-insulated connections, including
the transmitter’s cable set, the earth pin and the connection to the utility.
▶Notify others who may be working on or around the utility.
WARNING
Removing the battery pack of the signal transmitter
Removing the battery pack of the signal transmitter might cause you to receive
an electric shock.
Precautions:
▶Switch the signal transmitter off and remove any cable set or accessories
from the connection socket before removing the battery pack.
WARNING
Battery pack of the signal transmitter may get hot after prolonged use.
Risk of burning injuries.
Precautions:
▶Avoid touching the hot battery pack.
▶Allow the battery pack to cool down before removing it.

1.7 FCC Statement, Applicable in U.S.
☞The greyed paragraph below is only applicable for products without
radio.
14 Safety Directions

WARNING
This equipment has been tested and found to comply with the limits for a
Class B digital device, pursuant to part 15 of the FCC rules.
These limits are designed to provide reasonable protection against harmful
interference in a residential installation.
This equipment generates, uses and can radiate radio frequency energy and,
if not installed and used in accordance with the instructions, may cause
harmful interference to radio communications. However, there is no guaran-
tee that interference will not occur in a particular installation.
If this equipment does cause harmful interference to radio or television
reception, which can be determined by turning the equipment off and on,
the user is encouraged to try to correct the interference by one or more of
the following measures:
•Reorient or relocate the receiving antenna.
•Increase the separation between the equipment and the receiver.
•Connect the equipment into an outlet on a circuit different from that to
which the receiver is connected.
•Consult the dealer or an experienced radio/TV technician for help.
CAUTION
Changes or modifications not expressly approved by Leica Geosystems for
compliance could void the user's authority to operate the equipment.

2 Description of the System
2.1 System Information
Locators are used to detect buried conductive utilities that emit an electromag-
netic signal. Such a signal is generated as an electrical current passes through
the utility.
Signal transmitters are used to apply a distinct signal to utilities with the fol-
lowing intention:
•To improve the detection success.
•To trace the route of a utility.
•To make a depth or current measurement.
Accessories are used with the locator and transmitter to localise the position
of utilities, including some that are non-metallic.
The locators and transmitters described within this manual greatly facilitate the
search process and help to reduce the dangers and costs associated with utility
strikes. However, electromagnetic location depends on the utilities being con-
ductive (metallic) and emitting a signal as current passes through them.
☞Keep in mind that a locator on its own cannot detect all utilities. Take
care when excavating. We recommend that you adopt a safe system
which includes the planning of the search process in advance, the use
of utility maps, the use of locators and transmitters, and the use of
safe digging practices.
