BTI MLL 150 Notice D'utilisation page 70

ENGLISH
Place the 9-volt battery in the compartment, aligning the battery as
shown on the embossed icon.
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 BTI 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).
