Switching On and Off
A loud audio signal sounds when switching on the measuring
tool. "The A-weighted sound pressure level of the audio signal
at a distance of one meter is 95 dB(A)."
Do not hold the measuring tool close to your ear! The loud au-
dio signal can cause hearing defects.
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 automatically switches off in or-
der to save the battery. The switching off is indicated by an audio
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 "me-
dium" is set.
