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 (23) 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 fi nish
in the narrow setting.
Magnets
The magnets (24) allow the detector to be mounted to the metal tracks during
the installation of a suspended ceiling.
DETECTOR OPERATION (FIG. F)
1. Set up and position the laser.
2. Turn the detector on by pressing the power button (21).
3. Position the detector so that the sensor window (25) is facing the laser
beam.
Move the detector up or down within the approximate area of the beam,
until you have centered the detector. For information about the display
window indicators and the audible signal indicators, refer to the table
titled Indicators.
