Product Usage Instructions

Brief Introduction

The device is a high-tech portable machine that combines the functions of a binocular and laser rangefinder. It can measure distance and speed while providing a clear image with features like high precision, short-ranging time, visual display, low consumption, and auto power-off.

• The device model is 10x42LRF with a magnification of 10X.
• It has a precision measurement of +/-1M up to 5-1000M and a speed field range of 0-300KM.
• The device is waterproof (IPx6) with dimensions of 155mm x 130mm x 62mm and weighs 950g.
• Press the power key to turn on the rangefinder. The default mode is ranging.
• Hold down the mode key to select the unit of distance (meter or yards). No need to change the unit when exchanging within different modes.
• A low battery symbol will appear when the battery voltage is low, indicating the need for battery replacement.
• Short press to select different modes such as Ranging, Scanning, Flagpole Lock, Fog, Angle, Altitude difference, Distance difference, and Speed mode.
• To start ranging, aim at the target and press the mode key. The device will display the distance on the screen.
• In Flagpole Lock mode, aim at the flagpole and start scanning. The device will automatically lock the flagpole distance while shielding other goals behind the flagpole.
• The rangefinder handles interference caused by microparticles in fog to ensure precise measurement of distant targets.

FAQ

• Q: Is the device safe for the eyes and body?
• A: Yes, the device is safe to use thanks to the 905nm laser and multi-coated lens design.
• Q: How do I change the battery?
• A: To change the battery, locate the battery cover, remove it, and replace the old battery with a new one following the polarity markings.
• Q: Can I use the device with glasses?
• A: If you wear glasses, you can either remove them or adjust the eyepiece cups for a clear image.

BRIEF INTRODUCTION

The device is a high-tech portable machine, combining the factions of a binocular and laser range finder. It changes the distance measure and improves the efficiency.

• The device can measure the distance and speed while showing a clear image and has advanced such as high precision, short-ranging time, visual display, low consumption and auto power off.
• The device is safe to the eyes and body by using 905nm laser and multi-coated lens.
• Before the operation, please turn the body until the image through the two eyepieces focuses on one object. And then adjust the eyepieces until the image is clear. If you wear glasses, please remove the glasses or adjust the eyepiece cups.

Operating Instructions

1. The Boot Screen
   Press to turn on the rangefinder. The default mode is “ Picture 1

2. The Measurement Unit
   Hold down to select the unit of distance, meter or yards. (picture 2)

After selecting the mode “Ranging”, “Scanning”, “Flagpole Lock”, “Fog”, “Angle”, “Altitude difference”, and “Distance difference” hold down to select the measuring unit, no need to change the unit again when exchanging within these seven modes.
The measurement unit would be selected again separately in the “Speed” mode.

Low Battery

• A “low battery” symbol will appear when the battery voltage is low (Picture 3). The rangefinder will soon need battery replacement.

Mode Selection

• Short press to select the modes.

Ranging

• Principle (picture 4)
• Ranging screen (picture 5)

• Short press to start ranging (picture 6).

Flagpole lock

• Principle (picture 7); In this mode, point D may be isolated from several points in the background, while keeping only the distance d1 to the point, to achieve the automatic locking flagpole distance.
• The other goals are shielded behind the flagpole. Screen (picture 8).

• After choosing the flagpole lock mode, aim the device at the flagpole, ensuring the pole is in the center of the screen and press to start scanning.
• A box will appear in the center of the screen. When the box begins to flash a second box will appear around the flag symbol. After the flash, the data is locked. (picture 9).

Fog
Principle (picture 10)

The microparticles in the fog will reflect the riser, making it unable to measure the distant targets. To ensure precision, the rangefinder will handle the interference caused by the microparticles in the close distance (d1=25m). (picture 11)
Press the mode button until the “Fog” mode screen appears. Short press to start ranging. Fog screen (picture 12)

• “Angle”, “Altitude ranging”, and “Distance ranging” Principles (picture 13)

• A. Angle
• B. Ranging
• C. Distance ranging
• D. Altitude ranging

Press the mode button to choose the mode. Short press to start ranging. Ranging screen (pictures 14, 15, 16)

Speed
Principle (picture 17). Measure the target twice and get the speed by dividing the time and distance. (picture 18). Speed screen (picture 19)

• Press the mode button until the “Speed” mode screen appears. Hold down the mode button to select the unit of measurement. Short press to measure the speed. Kilometers per hour (KM/H) (picture 20). Miles per hour(M/H) (picture 21).

Scan

• Press the mode button until the “Scan” mode screen appears. Short press to measure the scan. Scan screen (picture 22)
• The laser will run continuously and all targets will show on the screen one by one (picture 23). The screen will automatically exit after 20 consecutive points are measured.

CAUTIONS

• The measurement range will be affected by the nature of the object, beam launch, angle with the target surface the weather, etc.
• When the low battery indicator is displayed, the battery should be replaced. Otherwise, the error will increase. When the device will not be used for a long time, please remove the battery from the device.
• Please do not look through the laser emission lens and objective lens when pressing, it may cause damage to your eyes.
• Please use a lens cleaning cloth to wipe the dirt gently. Using other objects may damage the coating on the lens.
• Please store in a dry and cool location. Avoid direct sunlight and dust.
• Please ask for help from a technician if the device is damaged. Do not disassemble by yourself.
