Preparation
Batteries
Your hearing instrument uses a battery as its power
source. The battery size can be identified by
the orange (13) or brown (312) 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.
4. Line up the battery’s plus “+” sign (flat side of
the battery) with the battery door “+” sign.
5. Close the battery door.
My hearing instrument uses:
312 Battery (brown color code on packaging)
13 Battery (orange color code on packaging)
