5. Troubleshooting
If you encounter issues with your Handstar TH810, refer to the following common problems and solutions:
- Inaccurate or inconsistent readings:
- Ensure the device is calibrated correctly by placing it flat on the wall before scanning.
- Scan slowly and consistently across the surface. Rapid movement can affect accuracy.
- Check the wall material. Very thick or uneven surfaces may reduce detection depth or accuracy.
- Re-calibrate the device in a different spot on the wall.
- No detection or device not turning on:
- Check the 9V battery. Replace it if the low battery indicator is shown or if the device does not power on.
- Ensure the device is held flat against the wall surface during calibration and scanning.
- False positives or constant alarms:
- Re-calibrate the device in an area of the wall that is known to be clear of objects.
- Move the device slower during scanning.
- Ensure your hand is not covering the sensor area.
