Once batteries are flush with the top of the battery drawer, gently
slide the battery drawer back into the battery cartridge. If the cells are
inserted incorrectly, the battery drawer will not close.
Then begin to attach the battery cartridge to the Sky CI by holding
the sound processor in one hand. Rotate RF cable upward to avoid
bumping it upon battery placement.
Align the battery cartridge connector with the processor housing side of
the connector.
