Dewalt Laser Distance Meter DWHT77100 (0.2 to 30 m Range, Laser Class 2, Measurement Tolerance: +/- 3 mm / 10 m, Length, Areas, Volume & Pythagoras Measurements, Easy Operation)

Product Information

Press and hold the gear button (Figure A ) for 3 seconds. The measurement reference location icon (Figure C ) will flash on the display window. Total Tools reserve the right to terminate or amend the price guarantee policy at any time without notice. For Further Information You can use the distance to two points on a tall object (Indirect Height) to determine its height (Figure I1). Slide the pins at the bottom of the battery door into the notches in the battery compartment (Figure E ). NOTE: Ensure the batteries are inserted in the correct manner, with the correct polarity. Setup (Load Batteries)

Switch the device on/off several times. If error still occurs, return device to Service Center or Distributor Press the gear button (Figure A ) three times to show the indirect measurement height on the display window (Figure E ). Position the tool at one end of the target and point the laser dot across the width. (Figure G shows where to position the tool if you are measuring from the top of the tool.) Press On button (Figure A ) to measure the distance from the tool to the wall or object. Refer to Setup LDM to change the reference location and / or unit of measurement. DO NOT mix old and new batteries. Replace all of them at the same time with new batteries of the same brand and type.Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure. Battery Safety The following label information is placed on your laser tool to inform you of the laser class for your convenience and safety. Press the gear button (Figure A ) once to show the area icon (Figure B ) on the display window (Figure A ). Position the tool at one end of the target and point the laser dot across the length. (Figure G shows where to position the tool if measuring from the top of the tool.) At the bottom of the display window (Figure A ), view the current measurement (Figure C ), which will keep changing as you move the tool.

Once the current measurement is taken (the device is not in Continuous Measure mode), you can change the unit of measure from decimal ft (6.21 ft) to fractional ft (6'02"9/16), fractional ft to meters (1.894 m), meters to inches (74 9/16 in), or inches to decimal ft. Insert two AAA batteries, making sure to position the ‑ and + ends of each battery as noted inside the battery compartment (Figure E ). The DWHT77100 tools emit a visible laser beam, as shown in Figure A . The laser beam emitted is Laser Class 2 per IEC 60825‑1. Should you find one day that your DeWALT product needs replacement, or if it is of no further use to you, do not dispose of it with household waste. Make this product available for separate collection. Point the laser (Figure A ) toward the wall or object whose distance you need to measure (Figure F).

From the same point, aim the laser straight ahead toward the center of the building or object (Figure J3). Carefully read the Safety Instructions and Product Manual before using this product. The person responsible for the product must ensure that all users understand and adhere to these instructions. If you need to measure the height of a tall object (e.g., a tall building), you can calculate the height based on the distances from the same point to 2 or 3 points on the object. The tool will use the Pythagorean Theorem (A2+B2=C2) to calculate the height. Measure a distance with two measurements
