4. Maintenance
To ensure optimal performance and longevity of your TESSAN Power Strip, follow these simple maintenance guidelines:
- Cleaning: Disconnect the power strip from the wall outlet before cleaning. Use a dry, soft cloth to wipe the surface. Avoid using liquid cleaners or abrasive materials.
- Cable Management: Utilize the integrated Velcro strap on the cord to keep excess cable neatly bundled, preventing tangles and reducing clutter.
- Inspection: Periodically inspect the power strip and its cord for any signs of damage, such as frayed wires, cracks, or loose connections. If damage is found, discontinue use immediately.
5. Troubleshooting
If you encounter issues with your TESSAN Power Strip, refer to the following common troubleshooting steps:
- No Power to Devices:
- Ensure the power strip's on/off switch is in the 'ON' position.
- Verify the power strip is securely plugged into a working wall outlet.
- Check if the 'Protected' or 'Grounded' indicator lights are off. If so, the surge protection may have been compromised, or there's an issue with the wall outlet's grounding.
- Test the wall outlet with another device to confirm it is supplying power.
- Devices Not Charging via USB:
- Ensure the USB cables are properly connected to both the power strip and your device.
- Try using a different USB cable or a different USB port on the power strip.
- Confirm your device is compatible with the USB charging specifications (5V output).
- Overload Protection Tripped:
- If the power strip stops supplying power, it may have tripped its overload protection. Disconnect some devices to reduce the load.
- Press the reset button (if available, typically integrated with the on/off switch) to restore power.
