Insert one arm of your angled tweezers under the metal neck of the red antenna coaxial connector on the daughterboard and lift straight up to disconnect it.

Be gentle when removing the red antenna cable from its holder to avoid damaging the cable.

Repeat for the other connector.

During reassembly, use tweezers to hold the connector in place over its socket and gently press down with your finger or a spudger—the connector should "snap" into place. If you're having trouble, reposition the head and try again.
