Initial Operation

 Do not leave the switched-on measuring tool unattended and switch the mea-
suring tool off after use. Other persons could be blinded by the laser beam.
 Protect the measuring tool against moisture and direct sun light.
 Do not subject the measuring tool to extreme temperatures or variations in
temperature. As an example, do not leave it in vehicles for a long time. In case of
large variations in temperature, allow the measuring tool to adjust to the ambient
temperature before putting it into operation. In case of extreme temperatures or
variations in temperature, the accuracy of the measuring tool can be impaired.
 Avoid heavy impact to or falling down of the measuring tool. After severe exte-
rior effects to the measuring tool, it is recommended to carry out an accuracy
check (see "Accuracy Check of the Distance Measurement", page 42) each time
before continuing to work.
