🚫 What NEVER to Do (Common Misuse Warnings)

⚠️ Connecting the power supply to an input voltage different from the selected one (e.g., 110V on a 220V network).
err_01
Consequence: Immediate damage to the power supply.
✓ How to avoid: Always check and adjust the dual voltage selector to the correct voltage for your electrical network before powering on. 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.
