If the unit is within its working accuracy limits (± 20”) the maximum difference from true level at 20 m (65 ft.) + 20 m (65 ft.) = 40 m (130 ft.) is 4 mm (3/16 inch).

Repeat the above steps for “minus X” and for “plus-” and “minus Y”, so that a measurement for all four axes of the unit have been performed.

The accuracy of the detector has to be regarded.

PROTECTING THE UNIT

Do not expose the unit to extreme temperatures or temperature changes (do not leave inside the car).

The unit is very robust and can resist damage if dropped even from tripod height. Before continuing your work, always check the leveling accuracy. See Accuracy Check section.

The laser is water proof and can be used indoors and outdoors.

CLEANING AND MAINTENANCE

Dirt and water on the glass parts of laser or prism will influence beam quality and operating range considerably. Clean with cotton swabs.

Remove dirt on the housing with a lint-free, warm, wet and smooth cloth. Do not use harsh cleansers or solvents. Allow the unit to air dry after cleaning it.

PROTECTING THE ENVIRONMENT

The unit, accessories and packaging should be recycled. This manual is made of non-chlorine recycling paper.

All plastic parts are marked for recycling according to material type.

Do not throw used batteries into the garbage, water or fire. Remove them in compliance with environmental requirements.

WARRANTY

According to legal regulations, the warranty-period for this unit is 12 months for material and manufacturing defaults.

We do not take any liability for damages caused by a non-accurate unit.

Before starting to work, always carry out the Accuracy Check according to the corresponding

chapter.

This warranty is no longer valid if the unit is opened or the labels are removed.
