Take the batteries out of the measuring tool when you are not using it for a pro-
u
longed period of time. The batteries can corrode and self-discharge during pro-
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 33).

Switching On/Off

– To switch on the measuring tool and the laser, briefly press the measuring button (2)

Do not direct the laser beam at persons or animals and do not stare into the laser
u
beam yourself (even from a distance).
To switch off the measuring tool, press and hold the on/off button (5) [ ].
The values in the memory are retained when you switch the tool off.
