Press the 'UNIT' button repeatedly to cycle through the available measurement units: meters (m), inches (in), and feet (ft).
4.3 Changing Measurement Reference Point
Press the 'Reference Point' button to switch between measuring from the front edge or the rear edge of the device. An icon on the display will indicate the current reference point.
4.4 Single Distance Measurement
- Point the laser at the target surface.
- Press the 'READ' button once to activate the laser.
- Press the 'READ' button again to take the measurement. The distance will be displayed on the screen.
4.5 Continuous Measurement (Tracking)
- Press and hold the 'READ' button for 2 seconds. The device will enter continuous measurement mode.
- Move the device to track distances. The display will show real-time measurements, including maximum and minimum values.
- Press 'READ' again to exit continuous measurement.
4.6 Area Measurement
This mode calculates the area of a surface.
- Press the 'Area/Volume' button once. The area icon will appear on the display.
- Take the first measurement (e.g., length) by pressing 'READ'.
- Take the second measurement (e.g., width) by pressing 'READ'.
- The device will automatically calculate and display the area.
4.7 Volume Measurement
This mode calculates the volume of a space.
- Press the 'Area/Volume' button twice. The volume icon will appear on the display.
- Take the first measurement (e.g., length) by pressing 'READ'.
- Take the second measurement (e.g., width) by pressing 'READ'.
- Take the third measurement (e.g., height) by pressing 'READ'.
- The device will automatically calculate and display the volume.
4.8 Pythagorean Measurement
This mode allows indirect measurement of heights or distances using the Pythagorean theorem.
- Press the 'Pythagorean' button. The Pythagorean icon will appear on the display, indicating which sides need to be measured.
- Follow the on-screen prompts to measure the required sides (e.g., hypotenuse, one leg).
- The device will calculate and display the unknown side.
4.9 Adding and Subtracting Measurements
After taking a measurement, you can add or subtract subsequent measurements:
- Press the 'Plus' button, then take a new measurement. The result will be added to the previous one.
- Press the 'Minus' button, then take a new measurement. The result will be subtracted from the previous one.

7. Troubleshooting
If you encounter issues with your Retoo Laser Distance Meter E026, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not turn on. | Depleted or incorrectly installed batteries. | Check battery installation and replace with new AAA batteries if necessary. |
| Inaccurate measurements. | Target surface is too reflective, transparent, or rough; laser lens is dirty. | Measure against a solid, non-reflective surface. Clean the laser lens with a soft cloth. Avoid measuring through glass. |
| Laser beam is not visible. | Bright ambient light (e.g., direct sunlight). | Use the device in shaded areas or indoors. The laser is less visible in bright conditions. |
| Error message on display. | Measurement out of range, or internal error. | Ensure target is within the 0.03m to 40m range. Try restarting the device. If the error persists, contact support. |
