err_01
Consequence: Physical damage to the USB connectors on the Hub and/or device, leading to loss of functionality.
✓ How to avoid: Connect USB cables carefully and with correct alignment, without forcing. If you feel resistance, check the alignment. Note: Standard US wall outlets supply 120V. This 220V-240V appliance requires a dedicated 220V-240V outlet or a high-wattage step-up voltage converter to operate in the US.
