IMPORTANT INFORMATION Read prior to activation You have just purchased a sophisticated electro-optical device that emits invisible laser radiation. To operate it properly, please, read this manual carefully. NEVER direct laser beam at the eyes of people or animals NEVER aim the unit at the Sun or bright sources of light NEVER subject the unit to impacts NEVER transport the unit without the case NEVER disassemble the unit. This may be hazardous for you due to high voltage c

Avoid eye exposure to direct laser beam or its close reflection Prevent bright light from focussing through the eyepiece Never aim the unit at highly reflective objects like mirrors and retroreflective surfaces, which are in close proximity to the laser rangefinder. This can lead to the permanent damage of the photoreceiver incorporated into the device.

Changing battery To install a battery: Slide the battery compartment cover down (9, Fig. 2) Install the battery observing polarity Don’t apply superfluous strength while pushing the battery inside the compartment. Close the compartment cover If the battery does not fit the compartment easily, it means that polarity was reversed To take a battery out: Slide the battery compartment cover down (9, Fig. 2) Shake the rangefinder gently towards the open end of the battery comp

Measuring procedure To start the measuring procedure, remove the lens cover. Look through the eyepiece (1, Fig. 1, 2) and adjust the focus by its rotating. When the Rangefinder is off the LCD is blank. To activate it press and hold A button (6, Fig. 1) for half a second. At start the unit comes into Ready to Measure mode indicated by the word ‘READY’ on the display visible through eyepiece. You may need to adjust the focus again so that both the display and distant objects are seen s

Target reflectivity depends on its color, surface finish, size, shape, position in relation to the laser beam, etc. Bright target colors are more reflective than darks. A polished surface is more reflective than a rough one. Larger targets reflect better than small ones. Ranging a target perpendicular to the laser beam provides better results than the one positioned under a sharp angle to the beam. Weather conditions that influence air transparency (rain, fog, snow, mist) reduce maximum

KMH/MPH: units of speed measurement: km/hour or miles/hour (3, Fig.3) (LRM 1800S only). Shape of the reticle: cross shape or rectangular shape (2, Fig.3). rEC1: Data Recall mode. It returns results of the last 10 measurements on the display. Measurement results are saved in on-board memory. When you enter the Data Recall mode, first measurement set number (display name: rEc 1) will appear. Pressing M button moves the unit along the list of measurement set numbers and measurement res

Additional display information Distance measuring procedure includes instant statistical processing of the package of single measuring sessions. If there is more than one measured target in the field of view, the embedded software estimates the most probable one by calculating the number of reflected pulses multiplied by the target statistical weight. This mechanism allows automatic mitigation of the influence of obstacles like rain, flakes, trees, wires and so on. Qualitative result

6. STORAGE AND MAINTENANCE The unit is a sophisticated precision optical instrument equipped with laser and electronics. Therefore, it should be handled with due care. Keep away from direct sunlight. Avoid impacts, jolts, dust, moisture, and sharp changes of temperature. o Do not use the device at temperatures higher than 50 C o (122 F). Prevent unit from direct sunlight Do not touch optical surfaces. Doing so may damage the anti-reflection coating. Clean optical surfaces

7. TROUBLESHOOTING The ranging does not work. The display is transparent. Check the charge of the battery. Replace it if it is weak. Black dots are visible on LCD. Liquid Crystal Display may have small black dots, scratches and other blemishes inherited from the manufacturing process. These flaws are strictly regulated by number, area and location and do not degrade the product's measurement capabilities. Range measurement cannot be obtained. Make sure that neither your hand nor finge
