Advanced Bionics CI-5501 Instructions For Use Manual page 12

Place two Zn-Air cells, positive (flat) side up, in the two
openings in the battery drawer.
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 Naída CI
by holding the sound processor in one hand. Rotate RF
cable upward to avoid bumping it upon battery placement.
