Insertion of batteries

1
Open the battery compartment (14)

symbols. Be sure to pay attention
to polarity.

Working with the laser receiver

2
Use the laser receiver for levelling over great distances or in very bright
conditions. Switch it on with button 4.
Set the line laser to hand receiver mode. The laser lines will now pulsate
with high frequency, making the laser lines darker. The laser receiver can
detect these pulsating laser lines up to a maximum distance of 50 m.
Now move the receive field (7) on the laser receiver up and down through the
laser lines until the middle LED lights up. Now mark the reference dimension.
!
Pay attention that the laser lines are not reflected by reflective surfaces.
Such reflections can lead to false indications.
