Operating Instructions

- No additional user interaction is required for the basic operation of the power adapter itself.
- Ensure the power adapter is placed in an area with adequate ventilation and is not covered or obstructed during use to prevent overheating.
Maintenance

- Environmental Conditions: Avoid exposing the adapter to moisture, direct sunlight, or extreme temperatures.
- Inspection: Regularly inspect the power cable and connectors for any signs of damage, such as kinks, cuts, or frayed wires.
- Damage: If any damage is observed, discontinue use immediately and replace the adapter. Do not attempt to open or repair the adapter yourself.
Troubleshooting
If you encounter issues with your power adapter, please refer to the following common problems and solutions:
- No Power to Scale:
- Check if the power adapter is securely plugged into both the wall outlet and the scale.
- Verify that the wall outlet is functional by testing it with another electrical device.
- Ensure the scale itself is powered on and functioning correctly according to its own manual.
- Intermittent Power:
- Inspect the entire length of the cable for any visible damage, kinks, or cuts.
- Ensure the connectors are clean and free of debris, which could hinder a stable connection.
- Adapter is Excessively Hot:
- A slight warmth during operation is normal. However, if the adapter becomes excessively hot to the touch, disconnect it immediately from the power source and the scale. This may indicate an internal issue or overload.
