5. Maintenance
Cleaning:
To clean the device, use a soft, dry cloth. For stubborn marks on the aluminum alloy body or tempered glass screen, a slightly damp cloth can be used, followed by immediate drying. Avoid using abrasive cleaners, solvents, or harsh chemicals, as these can damage the finish and screen coating.
Storage:
Store the DUKA LS5 in a cool, dry place away from direct sunlight and extreme temperatures. When not in use for extended periods, ensure the battery is partially charged (around 50%) to prolong its lifespan.
Screen Durability:
The device features a 4H tempered glass screen, designed to be highly resistant to impacts and daily scratches, ensuring high-definition display and sensitivity over time.
6. Troubleshooting
If you encounter any issues with your DUKA LS5, please refer to the following common troubleshooting steps:
- Device not powering on: Ensure the device is fully charged. Connect it to a power source using the Type-C cable and allow it to charge for at least 30 minutes before attempting to power it on again.
- Inaccurate measurements: Ensure the laser aperture is clean and unobstructed. Make sure you are measuring to a stable, non-reflective surface. Environmental factors like strong light or extreme temperatures can affect accuracy.
- Screen unresponsive: Try restarting the device by holding down the power area on the touch screen. If the issue persists, ensure the screen is clean and dry.
- Battery draining quickly: Ensure the device is fully charged. If the issue continues, it might indicate a battery degradation.
For persistent problems not resolved by these steps, please contact customer support.
