Always replace all the batteries/rechargeable batteries at the same time. Only use
batteries/rechargeable batteries from the same manufacturer and which have the
same capacity.
When inserting the batteries, ensure that the polarity is correct according to the il-
lustration on the inside of the battery compartment.
When the empty battery symbol first appears on the display, only a limited number of
measurements are still possible.
When the battery symbol is empty and flashes red, no further measurements are possible.

Operation
Start-Up
u
Never leave the measuring tool unattended when switched on, and ensure the
measuring tool is switched off after use.
Others may be dazzled by the laser beam.

Do not expose the measuring tool to any extreme temperatures or variations in
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 ambient
temperature before putting it into operation. The precision of the measuring tool may
be compromised if exposed to extreme temperatures or variations in temperature.

After strong
external influences on the measuring tool, you should always carry out an accuracy
check (see "Accuracy Check", page 36) before further work.
