Changing the Battery
Open the battery compartment by turning the instrument
o, and then using your ngernail to open it completely.
After removing the old battery, insert the new one with the
“+” (at) side facing the “+” on the battery door. It should t
in like a puzzle piece. The battery door should close very
easily. Never use force to close the door as this may damage
your hearing instrument.
Always use a Zinc-Air battery. Please note that if the bat-
tery is weak, the hearing instrument performance will be
reduced. Removing the battery when you are not wearing
the instrument will help prevent corrosion of the battery
contacts.
