Using the Phillips bit PH1 from the 26 Bit Driver Kit, remove the three screws keeping the orange battery cover held in place. Keep track of these screws as well; they are not the same type of screw used to secure the bottom gray panel.

This part will take patience, as the PH1 bit may not fit perfectly within the threads of the screws. Applying a firm amount of pressure while unscrewing makes this process easier.
