Inserting/Changing the Batteries
It is recommended that you use alkaline manganese or rechargeable batteries to operate
the measuring tool.
With 1.2 V batteries fewer measurements could be possible than with 1.5 V batteries.
Press the locking mechanism (4) to open the battery compartment cover (3) and re-
move the battery compartment cover. Insert the batteries. When inserting, pay attention
to the correct polarity according to the representation on the inside of the battery com-
partment.
If the battery symbol appears on the display for the first time, at least another 100 in-
dividual measurements are possible. When the battery symbol
place the 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.
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 23).
