Setup and Installation
- Unpack the Power Strip: Carefully remove the power strip from its packaging. Inspect it for any signs of damage.
- Choose a Location: Place the power strip on a stable, flat surface, or consider wall mounting. Ensure the location is dry and away from heat sources or direct sunlight.
- Connect to Wall Outlet: Plug the power strip's 3-prong cord into a standard, grounded 100-250V AC wall outlet.
- Connect Devices:
- For AC-powered devices, plug them into any of the 8 AC outlets. Utilize the widely spaced outlets for larger adapters.
- For USB-powered devices, plug their USB charging cables into the 4 USB ports. The Smart IQ Identification feature will automatically optimize charging.
- Wall Mounting (Optional):
- Locate the keyhole slots on the back of the power strip.
- Mark the desired mounting position on the wall or baseboard.
- Install two screws (not included) into the wall, ensuring they are spaced correctly to align with the keyhole slots. Leave a small gap between the screw head and the wall.
