Detector Controls (fig. 9)
The detector is controlled by the power button (q) and the volume
button (r).
When the power button is pushed once, the detector is turned on. The
top of the sensor window shows the ON icon and the volume icon.
The Berner Digital Laser Detector also has an auto shut-off feature. If a
laser beam does not strike the beam detection window, or if no buttons
are pressed, the detector will shut itself off in about 5 minutes.
To turn off the audible signal push the button again; the volume icon will
disappear.
The detector powers up in the narrow accuracy setting (icon appears in
the lower left corner). Press the accuracy button (s) once to change to
wide accuracy setting (icon now appears in the lower right corner).
Accuracy
The detector provides two accuracy settings, wide and narrow. In the
wide setting, the detector provides a larger tolerance for indicating
that the detector is "on grade". In the narrow setting, this tolerance is
reduced for more accurate indication of "on grade".
For the most accurate results, start the work using the wide setting and
finish in the narrow setting.
Magnets
The magnets (t) allow the detector to be mounted to the metal tracks
during the installation of a suspended ceiling.
DETECTOR OPERATION (FIG. 9)
1. Set up and position the laser.
2. Turn the detector on by pressing the power button (q).
3. Position the detector so that the sensor window (u) is facing
the laser beam. Move the detector up or down within the
approximate area of the beam, until you have centred the
detector. For information about the display window indicators
and the audible signal indicators, refer to the table titled
Indicators.
