PRODUCT CHARACTERISTICS

A laser rangefinder is an optical instrument which allows you to measure the distance, height and speed of an object within the measuring range. Measurement is performed by means of a laser beam with a wavelength outside the visible range. The instrument is equipped with a telescope with a display, which allows for easy and quick measurement. Thanks to its battery power supply and low weight, the rangefinder is perfect for tourists and athletes. Before using the instrument, read the entire manual and follow its instructions. Keep this manual for later reference.

CAUTION! This rangefinder is not a measuring instrument within the meaning of the Trade Metrology Act.

ACCESSORIES

The product is supplied without batteries. A cover is supplied with the rangefinder.

GENERAL INSTRUCTIONS

The laser beam used in the device has a wavelength outside the range visible to the human eye, but you should never point the laser beam emitter towards people and animals. Do not look at the laser beam emitter. The laser is class two and emits a beam of the wavelength and power specified in the technical data table. Such a beam does not pose a threat, but aiming it directing at the eyeball may cause eye damage. Do not try to disassemble the device yourself, as it could expose you to laser radiation. Do not modify the device, especially the laser system. Do not use the device in an environment where the ambient temperature is outside the operating range. If the instrument is stored in a temperature beyond the operating range, wait until the instrument within the operating range, before using it. The product is not resistant to water and dust penetration. Never immerse the product in water or any other liquid. Do not place the device with other tools in the toolbox. Impacts can damage the rangefinder. Transport the device in the supplied case. Remove the battery from the device, if it is not used for a longer period of time. Do not store the rangefinder at temperatures above 50°C, as this can damage the LCD screen. Use a soft, clean, slightly damp cloth to clean the device. Avoid touching the lenses of the telescope and the laser emitter with your fingers. The laser beam must reach its target, then reflect and return to the device. As a result, the measurement conditions are subject to limitations. Too bright light at the measuring point or too reflective a surface, e.g. glass, can make measurement difficult or impossible. In this case, change the measurement conditions or select the appropriate measurement method. Pay attention to the environment during measurement with the telescope held close to the eye. Focusing on a point in the distance may cause the danger near the user to go unnoticed. Do not move around with the telescope held close to the eye, as this could result in a fall and serious injury. Never point the telescope and the emitter towards the sun, as this can damage the eyesight and the device.

Installing and replacing batteries

The battery compartment is located on the bottom of the device. Open the battery compartment cover and install two batteries. Pay attention to the correct polarity of the batteries. After installing the batteries, close the battery compartment cover. Ni-Mh batteries can also be used to power the product, but be aware of the shorter operating time and lower efficiency at low temperatures. Always replace batteries in pairs. It is recommended to use alkaline batteries. If the low battery symbol appears on the display, the batteries must be replaced.

Starting and stopping the product

Pressing the on/off switch shortly will start the product. The viewfinder and the distance meas-

urement mode are displayed in the telescope. The power supply is automatically switched off approx. 15 seconds after the last press of any button.

Adjusting the eyepiece focus

Look through the eyepiece and keep turning its cover until the display is focused. Thanks to adjustable eyepiece focus, some people with myopia and hyperopia can use the rangefinder without corrective glasses.

Distance measurement

Press the change mode button until "M" or "Y" is displayed in the eyepiece. "M" is the measurement in metres and "Y" is the measurement in yards. Aim the rangefinder so that the measured object is inside a rectangle in the centre of the eyepiece. Press the on/off switch briefly and wait for the numerical reading of the distance. You can change the measuring unit by pressing and holding the change mode button until the symbol of the measuring unit changes in the eyepiece.

Angle measurement

Press the change mode button until the angle measurement symbol is displayed in the eye-piece. Measure in the same manner as when measuring the distance. The display in the eye-piece will alternate between the distance and the inclination of the rangefinder at the time of measurement. If the “-” sign is displayed before the angle value, this indicates the downward inclination of the rangefinder.

Height measurement

Press the change mode button until the height measurement symbol is displayed in the eye-piece. Measure in the same manner as when measuring the distance. The display in the eye-piece will alternate between the distance and height of the measured object relative to the height of the rangefinder. If the “-” sign is displayed before the height value, this indicates the downward inclination of the rangefinder.

Distance measurement in fog

Fog reflects and absorbs the laser beam, so the measurement in fog can be highly erroneous and is effective only over short distances not exceeding 30 m. Press the change mode button until the distance measurement in fog symbol is displayed in the eyepiece. Measure in the same manner as when performing standard distance measurement.

Speed measurement

The instrument is able to measure the speed of an object approaching or moving away from the rangefinder. The greater the angle between the laser beam and the direction of the moving object, the greater the measurement error. The most accurate measurement results will be obtained when the laser beam coincides with the direction of the object movement. Press the change mode button until the speed measurement symbol is displayed in the eyepiece. Press and hold the on/off switch to change the speed measurement unit. Press the on/off switch briefly to start measuring speed. Two distances and time between these measurements will be measured. Based on this, the average speed of the measured object will be calculated and displayed.

Tripod-mounted device operation

The instrument can be mounted on a tripod, using a threaded socket in the instrument base.

EN

Measurements using a tripod-mounted instrument are more accurate, as errors caused by vibration related to holding the instrument in hand are eliminated.
