When inserting, pay attention to the correct polarity according to the representation on
the inside of the battery compartment.
When the battery symbol appears on the display for the first time, at least another
100 measurements can be taken. Once the battery symbol is empty, you have to replace
the batteries/rechargeable batteries, because measurements are no longer possible.
Always replace all the batteries at the same time. Only use batteries from the same man-
ufacturer and which have the same capacity.
u
Take the batteries out of the measuring tool when you are not using it for a pro-
longed period of time
. The batteries can corrode and self-discharge during pro-
longed storage.
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.
u
Protect the measuring tool from moisture and direct sunlight.
u
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 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.
u
Avoid subjecting the measuring tool to violent jolts and falls.
Always carry out an
accuracy check before continuing work if the measuring tool has been subjected to
severe external influences (see "Accuracy check of the measuring tool", page 29).
