Reposition device. • Slow blinking icon – Device is charging properly. • Solid icon – Device is charged (some devices do not support this feature). • No icon – Not in charging mode (no device on unit) Note: • Thick or metal device cases can interfere with wireless charging. Removing such a case may improve wireless charging. • Wireless charging uses a magnetic field. Avoid pla cing any metal object or personal items with magnetic stripes (credit cards, bank cards, key cards, metal or magnetic phone cases) near the wireless charging area to prevent damage. • This unit is compatible with the Qi wireless charging standard. PMA wireless charging is not supported. The wireless charging process generates heat that may cause phones and chargers to get warm to the touch. This is natural for wireless charging devices. USB Charging (Unit Includes USB-C Port and Standard USB Port) FCC Radiation Exposure Sta tement This equipment complies with FCC RF radiation exposure limits set forth for an uncontrolled en vironment. This equipment should be installed and operated with minimum distance 20cm between the radiator & your body. • Warning: Changes or modifications to this unit not expres sly approved by the party responsible for compliance could void the user’s authority to operate the equipment. • NOTE: This equipment has been tes ted and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable prot ection against harmful interfer ence in a residential installation.
