Inserting/Replacing the Battery

Protect the tool against moisture and Alkali- manganese batteries are recommended for the measuring tool.

To open the battery lid 9, slide the latch 8 in the direction of the arrow and fold the battery lid up. Insert the batteries. When inserting, pay attention to the correct polarity according to the representation on the inside of the battery lid.

When the batteries are low, the battery low indicator 3 flashes red. Additionally, the laser beams flash for approx. 5 s every 10 minutes. When the flashing initially begins, the

measuring tool can be operated for approx. 1 more hour. When the batteries become empty, the laser beams flash one more time directly prior to the automatic shut-off. Always replace all batteries at the same time. Only use batteries from one brand and with the identical capacity.

Remove the batteries from the measuring tool when not using it for extended periods. When storing for extended periods, the batteries can corrode and discharge themselves.

Operation

Initial Operation

! WARNING	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 or falling of the measuring tool. After heavy exterior impact on the measuring tool, an accuracy check should always be carried out before continuing to work (see “Levelling Accuracy”).

Switch the measuring tool off during transport. When switching off, the levelling unit, which can be damaged in case of intense movement, is locked.

Switching On and Off

To switch on the measuring tool, slide the On/Off switch 4 to the “ on” position (when working without automatic levelling) or to the “ on” position (when working with automatic levelling). Immediately after switching on, the measuring tool sends laser beams out of the

exit openings 1.

!WARNING Do not point the laser b e a m at per s o n s o r

animals and do not look into the laser beam yourself, not even from a large distance.

To switch off the measuring tool, slide the On/Off switch 4 to the “off” position. When switching off, the levelling unit is locked.

Deactivating the Automatic Shut-off

When no button on the measuring tool is pressed for approx. 30 minutes, the measuring tool automatically switches off to save the batteries.

To switch on the measuring tool after automatic shut-off, either slide the On/Off switch 4 to the “off” position and then switch the measuring tool on again or press the operating mode button 2 once.
