Switching On and Off
A loud audio signal sounds when switching on the measuring
tool. Therefore, keep the measuring tool away from your ear
or other person when switching on. The loud audio signal can
cause hearing defects.
For switching on the measuring tool, briefly press button 5
("<1 sec on"). The direction indicators 4, 3 and 2 on the front and
rear side of the measuring tool light up for one second and a brief
audio signal sounds.
To indicate the operational readiness, the centre indicator 3 lights
up every 2 seconds when the receiver is switched on. As soon as
the laser beam runs through the reception area 6, the direction in-
dicators 4, 3 and 2 indicate only the height of the laser beam (see
"Direction Indicators", page 20).
To switch off the measuring tool, press button 5 for more than one
second (">1 sec off"). The switching off of the measuring tool is in-
dicated by the three direction indicators 4, 3 and 2 lighting up, and
a brief audio signal sounds.
When no pushbutton on the measuring tool is pressed for approx.
30 minutes and when no laser beam is impinged upon the recep-
tion area 6 for 30 minutes, the measuring tool switches off auto-
matically to save the batteries.
Direction Indicators
The direction indicators for bottom 4, centre 3 and top 2 (on both
the front and rear side of the measuring tool) as well as the audio
signal indicate the position of the rotating laser beam in the recep-
tion area 6.
When the laser beam runs through the reception area 6 the first
time, a single tone is signalled, even when the audio signal is
switched off.
