Inserting/Replacing the Batteries
AA alkaline batteries are recommended for the measuring tool.
To open the battery lid, press the latch in the direction of the
arrow and remove the battery lid. Insert the batteries. When
inserting, pay attention to the correct polarity according to the
representation on the inside of the battery compartment.
When the battery symbol
appears for the first time on the
display, measurements are still possible for approx. 15 minutes.
When the battery symbol flashes, the batteries must be
replaced; measurements are no longer possible.
Always replace all batteries at the same
time. Only use batteries from one
brand and with the identical capacity.
Remove the batteries from the tool when not using it for
extended periods. When storing for extended periods, the
batteries can corrode and discharge themselves.
Operation
Protect the tool against moisture and
direct sun irradiation.
Do not subject the tool to extreme temperatures or
variations in temperature. As an example, do not leave
it in vehicles for longer periods. In case of large variations
in temperature, allow the 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
tool can be impaired.
Avoid heavy impact or falling of the tool.
After heavy exterior
impact on the tool, an accuracy check should always be
carried out before continuing to work (see “Accuracy Check of
the Distance Measurement”, page 36).
DO NOT stare directly at the laser beam
or project the laser beam directly into
the eyes of others. Serious eye injury could result.
