5501H_Manuals 1/17/12 2:32 PM Page 2 Detector Usage Note: A green laser uses a specific detector for the green beam. Lasers will not perform accurately with red detectors. 1. Product Description A laser detector is an indispensable accessory when using rotary laser levels. The main function of the detector is to locate the position of laser signals transmitted by rotary lasers. This detection quickly and precisely provides the user with the horizontal and vertical references.

(A coin fits easily into this slot.) 2) Insert 3 AAA batteries (note polarity) and then rotate battery-box cap clockwise to close it. 3) When the battery voltage is low, the unit will display a low battery indicator and there will be a buzzing “reminder” sound every 2-4 seconds.
501H_Manuals 1/17/12 2:32 PM Page 5 2) Detecting horizontal laser level signals • Place the unit in a vertical position (verify by checking the horizontal vial bubble). • Make sure the receiving window (on front of detector) is facing the laser and is receiving the laser signal. - If the LCD shows a “down” arrow and emits rapid sounds, this indicates that the laser level signal is located below the detector (Fig. 8).
5501H_Manuals 1/17/12 2:32 PM Page 6 3) Detecting vertical laser level signals • Place the unit in a horizontal position. • Make sure the receiving window (on front of detector) is facing the laser and is receiving the laser signal. - If the LCD shows a “left” arrow and emits rapid sounds, this indicates that the laser signal is located to the right of the detector (Fig. 14). Fig.
5501H_Manuals 1/17/12 2:32 PM Page 7 With the sound function turned on: - If the laser signal is above the detector, a slow sound is emitted. - If the laser signal is below the detector, a rapid sound is emitted. - If the laser signal is aligned on the mid portion of the detector, a continuous sound is emitted. Note: Whether or not the sound function is in use, there is still indicator sound when you press the key.
5501H_Manuals 1/17/12 2:32 PM Page 8 (g) Low Battery Indicator If the LCD shows a blinking battery sign, it is indicating that you have low charge on your batteries and that you need to change them soon (Fig. 21). If the battery power is too low, the detector will shut off automatically. At this time, you must change the batteries in order to continue using the detector. Blink Fig. 21 5. Detector Maintenance • When you are done using the detector, return it to its packing case.
