6. Operation
6.1 Turning the device on/off
On:
Press «ON/OFF» button.
Off:
Hold the «ON/OFF» button down for 3 seconds (the hand-held receiver will turn itself off
automatically after 7 minutes if it is not actively being used).
Turn the front face of the receiver towards the laser device and ensure that the receiver window is
vertical to the line plane.
Move the receiver up and down until a signal sounds and/or until direction arrows become visible
on the display.
If the marking point on the receiver is above the laser beam, a fast, pulsing signal sound is audible
and an arrow pointing downwards appears on the display.
Move the receiver downwards in the direction of the arrow shown on the display.
If the marking point on the receiver is below the laser beam, a slow, pulsing signal sound is audible and
an arrow pointing upwards appears on the display.
Move the receiver upwards in the direction of the arrow shown on the display.
If an unbroken signal sound is audible and/or if only the central bar is still visible, the marking point is
exactly on the laser beam.
Mark the height of the laser beam on the marking points using a pen. The spirit level vial can be
used to align the receiver vertically in order to ensure that the marking points on the left and
right sides are at the same height.
