The adapter converts AC power into the DC power required by your device, ensuring reliable performance.
2. Safety Information

- Do not expose the adapter to water, moisture, or extreme temperatures.
- Avoid dropping or subjecting the adapter to severe impact.
- Do not attempt to disassemble or modify the adapter.

6. Operating Instructions
Once properly connected, the adapter will supply power to your Fuzion PS4B Pro or PS4B Shipping Scale. If your scale has a rechargeable battery, the adapter will also charge the battery while providing power to the device.
- Ensure the scale is turned off before connecting or disconnecting the adapter to prevent potential damage.
- The adapter is designed for continuous use, but it is recommended to unplug it when the scale is not in use for extended periods.
7. Maintenance
- Keep the adapter clean and free from dust. Use a dry, soft cloth for cleaning.
- Store the adapter in a cool, dry place when not in use.
- Regularly inspect the cable and connector for any signs of damage. If damage is found, discontinue use immediately.
8. Troubleshooting
- No Power to Device:
- Check if the adapter is securely plugged into both the wall outlet and the device.
- Verify that the wall outlet is functional by testing it with another device.
- Device Not Charging:
- Ensure the adapter is correctly connected.
- As noted in the safety section, if the device's rechargeable battery is old or damaged, it may no longer accept a charge. This is a battery issue, not an adapter malfunction.
- Adapter Overheating:
- Unplug the adapter immediately. Allow it to cool down.
- Ensure the adapter is used in a well-ventilated area and not covered.
- If overheating persists, discontinue use and contact support.
