Checking the accuracy of the horizontal line
(only Lino L360, L2P5, L2+, L2G+, and L2)
Place the Lock switch 3 in the "Unlocked" ( )
position.
Position the instrument approx. 5 m away from the
wall. Direct the instrument at the wall and switch on
with the LASER key 1. Activate the laser line with the
LASER key 1 and mark the intersection point of laser
crosshairs on the wall.
Swivel the instrument to the right and then to the

line from the marking. If the difference does not
exceed 3 mm, then the Leica Lino is within tolerance.
