Take the batteries out of the measuring tool when you are not using it for a pro-
u

longed storage.
Operation
Start-Up
Never leave the measuring tool unattended when switched on, and ensure the
u
measuring tool is switched off after use. Others may be dazzled by the laser beam.
Protect the measuring tool from moisture and direct sunlight.
u
Do not expose the measuring tool to any extreme temperatures or variations in
u
temperature. For example, do not leave it in a car for extended periods of time. In
case of large variations in temperature, allow the measuring tool to adjust to the ambi-
ent temperature before putting it into operation. The precision of the measuring tool
may be compromised if exposed to extreme temperatures or variations in temperat-
ure.
Avoid subjecting the measuring tool to violent jolts and falls. Always carry out an
u
accuracy check before continuing work if the measuring tool has been subjected to
severe external influences (see "Accuracy Check of the Distance Measurement",
page 12).
