Turning Your Unison
™
Hearing Instruments
On and Off
Your hearing devices have a three-position battery door
that acts as an off/on switch and that allows access to
the battery compartment.
To turn the hearing device on, close the battery door fully.
Note: If the start up mute is activated, your hearing devices
will not turn on until the program button is pushed.
To turn the hearing device off, partially open the battery
door. This position allows excess moisture to vent away
from the battery compartment. Note: If you have a high
power BTE with a 675 battery, you also have an on/off
switch in the volume control.
To replace the hearing device battery, fully open the
battery door for access to the battery compartment.

your index finger and thumb.
Use your thumb to open and
close the battery door.
