DETECTOR CONTROLS (FIG. 8)
The detector is controlled by the power button (N) and the volume
button (O).
When the power button is pushed once, the detector is turned on.
The top of the display window shows the ON icon and the volume
icon.
The D WALT Digital Laser Detector also has an auto shut-off
E
feature. If a rotary laser beam does not strike the beam detection
window, or if no buttons are pressed, the detector will shut itself off
in about 15 minutes.
To turn off the audible signal push the button a third time; the volume
icon will disappear.
Detector Operation (Fig. 9)
1. Set up and position the rotary laser that you will be using
according to the manufacturer's directions. Turn the laser on
and make sure that the laser is rotating and emitting a laser
beam.
NOTE: This detector has been designed to be used only with a
rotating laser. The detector will not work with a stationary beam
laser level.
2. Turn the detector on by pressing the power button (N).
3. Adjust the volume as desired as described in the Detector
Controls.
4. Position the detector so that the detector window (P) is facing
the laser beam produced by the rotary laser. 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 (Fig. 9).
