The battery must be inserted the correct way to work and to not cause damage
to the hearing aid.
New batteries have a bright coloured sticker which needs to be removed.
Removing the sticker reveals the positive (+) side of the battery. The other side
is negative (-) which has a ring around the edge.
Inside the battery drawer there is a drawing of which way the battery
should be inserted to assist further.
