Changing the Battery
When the battery power level is low, your hearing
instrument will beep at regular intervals. You should
be prepared to replace the battery. The time until
the hearing instrument stops working depends on
the battery type and manufacturer. Mercury-free
batteries generally cause earlier warning beeps.
Change batteries regularly
When your battery needs to be changed, you will hear
three beeps: a low tone, followed by a high tone and
another low tone. The exact battery life you experience
may vary, but you should expect approximately
200 hours of total hearing instrument use per battery.
Battery type
Stainless steel zinc-air batteries are recommended.
Your hearing instrument uses a #13A battery.
Note!
Never force the battery door open or closed.
