Preparation
Batteries
Your hearing system uses a battery as its power
source. This battery size can be identified by the
orange (13), 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.
4. Line up the battery’s “+” sign (flat side of the
battery) with the “+” on the battery door.
5. Close the battery door.
My hearing instrument uses a:
13 battery (ITE) – Orange
312 battery (ITC) – Brown
10 battery (CIC) – Yellow
