Peel off the blue protective film on the bottom and a sticky rubber pad underneath that can be adsorbed on a smooth table.
Remove the stainless steel sheet from the bottom and the interior is an injection molded structure.
The injection moulded structure is fixed with a snap between the aluminum alloy housing.
The aluminum alloy shell is removed, and the internal structure and the aluminum alloy shell are also fixed by black double-sided adhesive.
The aluminum alloy housing is equipped with a conductive sponge for grounding at the position corresponding to the input mother seat, and the QR code is the product serial number.
The left and right sides of the internal module are recessed with fixing screws, and the Lightning plug is also screwed.
The Lightning plug is secured with 4 screws.
The Lightning plug is screwed to a metal plate at the bottom.
Unscrew the fixing screws, separate the housing, and secure the circuit board between the aluminum bracket and the plastic base.
