When the battery symbol appears
dividual measurements are still possible.
When the battery symbol flashes, the batteries/rechargeable batteries must be re-
placed. Measurements are no longer possible.
Always replace all batteries/rechargeable batteries at the same time. Do not use dif-
ferent brands or types of batteries/rechargeable batteries together.
 Remove the batteries/rechargeable batteries from the measuring tool when
not using it for longer periods. When storing for longer periods, the batteries/re-
chargeable batteries can corrode and discharge themselves.
Operation
Initial Operation
 Do not leave the switched on measuring tool unattended and switch the mea-
suring tool off after use. Other persons could be blinded by the laser beam.
 Protect the measuring tool against moisture and direct sun light.
 Do not subject the measuring tool to extreme temperatures or variations in
temperature. As an example, do not leave it in vehicles for long time. In case of
large variations in temperature, allow the measuring tool to adjust to the ambient
temperature before putting it into operation. In case of extreme temperatures or
variations in temperature, the accuracy of the measuring tool can be impaired.
 Avoid heavy impact to or falling down of the measuring tool. After severe exte-
rior effects to the measuring tool, it is recommended to carry out an accuracy
check (see "Accuracy Check of the Distance Measurement", page 23) each time
before continuing to work.
Switching On and Off
To switch on the measuring tool, briefly press the measuring button 2. Measuring tool
and laser are switched on.
 Do not point the laser beam at persons or animals and do not look into the la-
ser beam yourself, not even from a large distance.
To switch off the measuring tool, press the measuring button 2 and hold it down.
Measuring Procedure (see figure A)
Once switched on, the measuring tool is in the length measurement mode.
The rear edge of the measuring tool is always the reference level for the measure-
ment.
