Batteries
Your hearing aid uses a battery as its power source.
This battery size can be identified by the brown (312)
or yellow (10) color code on the packaging.
To insert or replace the battery:
1. Use the nail grip on the battery door.
2. Open the battery door gently and remove
the old battery.
3. Remove the tab from the new battery.
Wait 3-5 minutes after removing tab before
inserting battery.
4. Align the battery’s “+” sign (flat side of the
battery) with the “+” on the battery door.
5. Close the battery door.
Battery Indicators
An indicator will sound when the battery voltage is
low. You have approximately five minutes
*
to replace
the battery. An indicator may also sound just before
the battery stops working.
* Actual time between low battery indicator and shut down will vary depending on
environmental noise levels and brand of battery used.
