Inserting/changing the batteries

It is recommended that you use alkaline manganese batteries to operate the measuring tool.

Push the locking mechanism (12) in the direction of the arrow to open the battery compartment cover (9) and remove the battery compartment cover. Insert the batteries supplied.

When inserting the batteries, ensure that the polarity is correct according to the illustration on the inside of the battery compartment.

If the batteries become weak, the laser lines will flash quickly for a few seconds.

Always replace all the batteries at the same time. Only use batteries from the same manufacturer and which have the same capacity.
