Initial Operation

 Protect the measuring tool against moisture and direct sun light.
 Do not subject the measuring tool to extreme temperatures or variations in
temperature. As an example, do not leave it in vehicles for a long time. In case of
large variations in temperature, allow the measuring tool to adjust to the ambient
temperature before putting it into operation. In case of extreme temperatures or
variations in temperature, the accuracy of the measuring tool can be impaired.
– Position the measuring tool at least 50 cm away from the rotational laser level. Po-
sition the measuring tool in such a manner that the laser beam can reach the recep-
tion area 6. Set the highest rotational speed on the rotational laser level.
Switching On and Off
 A loud audio signal sounds when switching on the measuring tool. "At a dis-
tance of 0.2 m, the A-weighted sound pressure level of the audio signal can be up
to 95 dB(A)."
 Do not hold the measuring tool close to your ear! The loud audio signal can
cause hearing defects.
To save energy, only switch the measuring tool on when you are using it.
– To switch on the measuring tool, press the On/Off button 1. Two audio signals
sound and all display indicators light up briefly.
– To switch off the measuring tool, press the On/Off button 1 again.
When no button is pressed on the measuring tool for approx. 10 minutes and when no
laser beam reaches the reception area 6 for 10 minutes, the measuring tool automat-
ically switches off in order to save the battery. The switching off is indicated by an au-
dio signal.
Selecting the Setting of the Centre Indicator
With button 2, you can specify with which accuracy the position of the laser beam is
indicated as central on the reception area:
– "Fine" adjustment, (indication g on the display),
– "Medium" adjustment, (indication b on the display).
An audio signal sounds when the accuracy setting is changed.
Whenever switching on the measuring tool, the accuracy level "medium" is set.
