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 indicated 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 reception area
6 for 30 minutes, the measuring tool switches off automatically 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 reception area 6.
When the laser beam runs through the reception area 6 the first time, a sin-
gle tone is signalled, even when the audio signal is switched off.
Laser beam too high: When the laser beam runs through the upper half
of the reception area 6, the direction "bottom" indicator 4 flashes. When
the audio signal is switched on, a slow pulsing signal sounds. In this case,
move the measuring tool upward in the direction of the arrow.
Laser beam too low: When the laser beam runs through the lower half
of the reception area 6, the direction "top" indicator 2 flashes. When the
audio signal is switched on, a fast pulsing signal sounds. In this case, move
the measuring tool downward in the direction of the arrow.
Laser beam centred: When the laser beam runs through the reception
area 6 at the height of the centre mark 7, then the centre indicator 3 flashes.
When the audio signal is switched on, a continuous signal sounds.
Audio Signal
The audio signal can be switched on and off. For this, briefly press push-
button 5 once ("<1 sec").
When the audio signal is switched on and off, the direction indicators 4, 3
and 2 light up briefly. When switching on, three audio signals sound; when
switching off, a single audio signal sounds.
When the laser beam runs through the reception area 6 the first time, a sin-
gle tone is signalled, even when the audio signal is switched off.
After the measuring tool has been switched on, the audio signal is always
switched on.
