English 9-volt battery in the compartment, aligning the battery as shown on the embossed icon (M). 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 DEWALT Digital Laser Detector also has an auto shut-off 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.
