Troubleshooting a Bosch GLM 20 Laser Measure can involve a few straightforward steps. Here’s a guide to help you identify and resolve common issues:

1. **Check the Power Source**:
– Ensure that the batteries are installed correctly. If the device is not turning on, try replacing the batteries with new ones.
– Make sure the battery terminals are clean and free from corrosion.

2. **Verify Measurement Accuracy**:
– Ensure that the laser is unobstructed and the surface you are measuring to is suitable (e.g., flat and not reflective).
– If you suspect measurement inaccuracies, perform several measurements on the same surface to check for consistency.

3. **Change Measurement Unit**:
– Make sure that the measurement unit is set correctly (e.g., meters or feet). The unit can typically be changed using the appropriate button on the device.

4. **Check Laser Alignment**:
– Confirm that the laser is properly aligned with the target point. If the laser dot is not visible or appears misaligned, it may be necessary to recalibrate the device.

5. **Calibration**:
– If measurements seem off consistently, you may need to recalibrate the device. Follow the instructions in the user manual for the calibration process.

6. **Examine the Display**:
– If the display is not functioning, check for signs of damage or water ingress. Also, try resetting the device by removing the batteries and reinserting them after a few minutes.

7. **Consult the Manual**:
– If you encounter specific error codes or messages on the display, consult the user manual for guidance on what these mean and how to resolve them.

8. **Environmental Factors**:
– Keep in mind that environmental factors such as bright sunlight or reflective surfaces can affect laser measurements. Try using the device in a different lighting condition or angle.

9. **Clean the Lens**:
– If the laser dot appears weak or distorted, clean the lens gently with a soft, dry cloth. Avoid using chemicals that could damage the lens.

If you go through these steps and the issue persists, consider contacting Bosch customer support for further assistance or take the device to a certified technician for repair.
