Electromagnetic Compatibility; Additional Safety Instructions - Hilti PLT 400 Original Bedienungsanleitung

▶ Check the accuracy of the product before use and several times during use.
▶ Readings taken in the vicinity of reflective objects or surfaces, through panes of glass or similar materials
can falsify the result of measurement.
▶ Mount the product on a suitable holder or bracket or on a tripod, or set it on a smooth, level surface.
▶ Do not work with surveyor's staffs in the vicinity of high-voltage electricity cables.
▶ Make sure that no other laser measuring tool that can influence your measurements is in use in the
vicinity.
▶ Do not permit the laser beam to project beyond the controlled area.
2.3 Laser classification for Class 2 laser products
The device complies with Laser Class 2 in accordance with IEC60825-1/EN60825-1:2014. These products
can be used without further protective measures.
CAUTION
Risk of injury! Do not direct the laser beam toward persons.
▶ Never look directly into the source of the laser beam. In the event of direct eye contact, close your eyes
and move your head out of the path of the laser beam.
2.4

Electromagnetic compatibility

Although the tool complies with the strict requirements of the applicable directives, Hilti cannot exclude the
following possibilities:
• The tool may cause interference to other devices (e.g. aircraft navigation equipment).
• The tool may be negatively affected by powerful electromagnetic radiation, possibly leading to incorrect
operation.
In these cases, or if you are otherwise unsure, confirmatory measurements should be made by other means.

Additional safety instructions

▶ Before starting measuring work, make sure that the accuracy of the measuring tools used is adequate
for the requirements of the task.
▶ When a tripod or wall mount is used, make sure that the measuring tool is correctly and securely mounted
and that the tripod is standing firmly on solid ground.
▶ As a precaution, check the previous settings or any adjustments you may have made.
▶ Fasten the battery compartment cover carefully so that the battery doesn't fall out. If battery contact is
lost the PLT 400 will switch itself off, possibly leading to loss of data.
▶ Operation of the measuring tool in the vicinity of military installations, airports or radio astronomy facilities
is not permissible unless prior permission has been obtained.
▶ When switching distance measuring mode from prism measurement to reflectorless measurement, make
sure that no one can look into the lens of the PLT 400.
▶ Do not point the PLT 400 or accessories toward the sun or other powerful light sources.
▶ Measurements to plastic foam surfaces, e.g. polystyrene foam, to snow or to highly reflective surfaces,
etc. may result in incorrect readings.
▶ Measurements taken to surfaces with low reflectivity in highly reflective surroundings may be inaccurate.
▶ Use of setting-up / adjusting devices and equipment or operating procedures other than those specified
in these instructions may lead to exposure to hazardous radiation.
▶ Always observe the operating instructions and warnings given in the applications displayed.
2.6 Careful handling and use of batteries
▶ Comply with the following safety instructions for the safe handling and use of Li-ion batteries.
Failure to comply can lead to skin irritation, severe corrosive injury, chemical burns, fire and/or explosion.
▶ Use only batteries that are in perfect working order.
▶ Treat batteries with care in order to avoid damage and prevent leakage of fluids that are extremely
harmful to health!
▶ Do not under any circumstances modify or tamper with batteries!
▶ Do not disassemble, crush or incinerate batteries and do not subject them to temperatures over 80 °C
(176 °F).
