OPT LOGIC Operating Instructions for the Laser Rangefinder Hypsometer 100LH 400LH 600LH 800LH 1000LH The Opti Logic LH series Laser Rangefinder Hypsometer height measurement system combines a pulsed laser rangefinder and a vertical angle sensor in a lightweight easy to use package The hand held rangefinder is capable of measuring distances to non cooperative targets up to 1000 yards away Model 1000LH depending on target size and reflectivity Incorporating an internal electronic tilt sensor the Laser Rangefinder Hypsometer makes vertical angle measurements with better than 1 degree resolution to remotely determine object heights Applications of the hypsometer measurement system include tree height measurements construction utilities architectural measurements landscaping real estate appraisal and much more The system is ideal for applications where surveying quality measurements are not required and higher instrument cost is not justifiable This product is designed for years of trouble free operation and is proudly Made in the USA 1 0 Product Description and Features Viewfinder Look through the viewfinder window and aim the Red Dot at an object Range Button Press the Range button to take distance or height measurements or to select modes Display The Opti Logic Rangefinder Hypsometer is User Programmable to read in either Feet Meters or Yards Low Battery Replace the battery when the Lo2. THE LENSES After cleaning the lenses gently wipe the lenses off with a soft dry cloth NEVER use petroleum products or chemicals to clean the lenses or any parts Use the same procedure to clean the exterior Although the Opti Logic Laser Rangefinder Hypsometer has been designed to withstand normal outdoor use some common sense precautions should be observed NEVER subject your laser rangefinder to shock high temperature or harmful chemicals or gases If the Rangefinder is not going to be used for long periods of time remove the battery and store in a cool dry place DO NOT use chemicals or solvents to clean the Rangefinder Chemicals insect repellents and solvents can damage the plastic housing and lenses of the Rangefinder 4 0 Low Battery Indicator When the battery voltage becomes too low the instrument may act erratically or cease to function The low battery indicator will appear in the display before this occurs The battery should be replaced as soon as possible after the indicator is displayed 4 1 Errors Troubleshooting When a new battery is installed in the Opti Logic Laser Rangefinder Hypsometer diagnostic checks are performed by the onboard computer These tests check the basic operation of the Rangefinder During the normal diagnostic the display cycles from 000 999 then the display clears and is followed by a single beep If the unit is unable to obtain a range or angle measurement seems to locks up or a

8. ppears to be operating incorrectly there are a few steps you can take to correct this Page 2 of 2 A If the unit locks up remove the battery for several seconds and press the range button with no battery installed then reinstall the battery If problem continues try a new battery B If the Rangefinder displays an incorrect distance make sure that the Red Dot in the viewfinder is hitting the object Try aiming the Rangefinder at a nearby reflective target such as a street sign or automobile license plate to verify alignment C If the Rangefinder shows a distance of 0 the Rangefinder is hitting an object at a distance that is less than the minimum distance Try aiming the Rangefinder at a more distant object to verify operation D Make sure the battery terminals are in contact with the metal battery clips when replacing old battery 4 2 Technical Support and Maintenance For questions regarding the Opti Logic Laser Hypsometer Rangefinder or if problems persist make a note of the instrument serial number and date of manufacture and call Opti Logic Customer Service at 931 454 0897 8am to 5pm Monday thru Friday Central Time If your rangefinder requires maintenance your Customer Service Representative will assign you a Return Merchandise Authorization Number RMA and provide instructions for returning the instrument for repair When returning merchandise for maintenance or repair please be sure to include a brief wr
