V. Battery Installation

The product has a detachable and rechargeable 18650 lithium battery. When” ” (low battery indicator) is displayed, the battery should be charged or replaced in time, otherwise the measurement error will increase. If the product is not used for a long time, the battery should be removed.

1. Pull up the rotating handle on the battery cover and rotate ii 90° counter clockwise to open the cover, as shown in Figure 1 and Figure 2.

2. Put a battery into the battery compartment according to the polarity instructions, as shown in Figure 3. Please be sure to install the battery according to the anode and cathode, otherwise the product may be damaged due to a short circuit.

3. After the battery is installed, press down on the battery cover and rotate it 90′ clockwise, as shown in Figure 4. Then press down the rotating handle, as shown in Figure 5.

4. Please use the original USB cable to plug into a socket to charge, or connect the cable to a computer for charging, but it will take longer. After charging is complete, please close the USB protection cover to prevent dust from entering.

5. During the charging process, if the indicator light flashes, it indicates that the lithium battery is not inserted or the battery cover is not lightened. When the indicator light is on, it is charging. When the indicator light is off, the charging is complete.

VI. Initial Operation and Settings Eyepiece

The eyepiece knob can be rotated to adjust the diopter, making the observed target clearer (see the figure below).

Power on/off
Press the power button to turn the product on. If there is no operation within 16 seconds, the rangefinder will automatically shut down.

Angle Calibration
The rangefinder has been calibrated before leaving the factory. If the measurement data is inaccurate in the two point distance measurement mode, long press the power button in the shutdown state to enter the calibration interface. The interface will display “ANGLE CAL”. Keep the product in a stationary state, and the calibration will be completed after a few seconds. If the calibration cannot be completed for a long time, the rangefinder will automatically shut down in about 1 minute, that is, the calibration has failed.

If the calibration fails, the factory calibration will continue to be used when restarting.

VII. Operating Instructions

Short press O to switch measurement modes.

• Before measuring, please adjust the eyepiece knob to make the target clear. If the target reflection is weak or out of the measuring range during measurement, “—” will be displayed.
• The range of the rangefinder is related to the nature of the measured target, the tilt angle of the target surface, and the weather visibility. Generally speaking, if the target surface is smooth, bright, large and perpendicular to the beam, and the weather is cloudy and fogless, the longer the range, and vice versa.

VIII. Flagpole Lock Mode (Close Range Priority)

Distance + Tilt Angle
This mode is mainly used to measure the distance of small objects, and adopts the principle of close range priority. Short press Oto switch to (E) the flagpole lock mode. Aim the aiming dot at the measured object B, and then short press(!) to measure the distance from point A to point B.

Aim the aiming dot at point B, and then short press c!) to measure the distance from point A to point B and angle a (the angle between the distance and the horizontal plane). Then aim the aiming dot at point C, and short press c!> to measure the distance from
point A to point C and angle 13 (the angle between the distance and the horizontal plane). The vertical height between point B and point C is displayed on the top of the screen, and the absolute value of the difference between the measured angles is displayed at the bottom right of the screen (Note: the height between two points is the
vertical height on the same plane).

XI. Two-Point Distance Measurement Mode (Point to Point)

Short press • to switch to -q the two-point distance measurement mode.
Aim the aiming dot at point B, and then short press ® to measure the distance from point A to point B. Then aim the aiming dot at point C, and short press c!) to measure the distance from point A to point C. The distance from point B to point C and angle a are displayed on the screen.

Note: When measuring, please keep the standing position unchanged.

XII. Vertical Height Measurement Mode

Distance + Vertical Height + Tilt Angle Short press Oto switch to. di vertical height measurement mode. Aim the aiming dot at point B, and then short press .

The distance from point A to point B is displayed at the top of the screen, the vertical height from point B to point C is displayed at the bottom of the screen, and the tilt angle is displayed at the bottom right of the screen.

XIII. Horizontal Distance Measurement Mode

Distance + Horizontal Distance + Tilt Angle Short press Oto switch to~ horizontal distance measurement mode. Aim the aiming dot at point B, and then short press .

The distance from point A to point B is displayed at the top of the screen, the horizontal distance from point A to point C is displayed at the bottom of the screen, and the tilt angle is displayed at the bottom right of the screen.

XIV. Technical Specifications

Cautions

1. Do not touch the lens surface with fingers to avoid damaging the film on the surface.
2. The rangefinder is precisely adjusted by the instrument, so please do not disassemble it randomly. If the product is damaged, send it to a professional maintenance department for repair.
3. Avoid direct laser exposure for a long lime to prevent burns to the skin.
4. When the lens is contaminated, please gently wipe it with a soft cloth. Do not wipe it with other objects; otherwise the film on the lens surface may be damaged.
5. Do not bump, press, bake or corrode the product.
6. The product should be stored in a dry, cool, and ventilated place to avoid direct sunlight, dust and sudden temperature changes.
7. Measurement in rainy and foggy weather will affect the round-trip time of the laser, which may increase the measurement error, and even cause the measurement value to be wrong in severe cases.
