Battery
The hearing device uses a size 312 battery. The battery life varies, depending on the amount of time the hearing device
is used. Battery life is typically 5-8 days long in hearing device mode.
Inserting/replacing the battery:
1.
Gently pull open the battery door with your fingernail. Remove the old battery, if present.
2.
Insert the new battery into the battery compartment with the (+) sign on the battery facing the same way as the
(+) sign on the battery door. While holding the battery in place, peel off the tab. (As shown in the figure below.)
To ensure best battery performance, wait 15-30 seconds before closing the battery door after
peeling the plastic tab. If the door does not close easily, check to see if the battery was inserted
properly.
3.
Close the battery door.
Tip: To prolong battery life, remember to turn your hearing device off when not in use.
Remove the batteries and keep the battery door open will not only conserve the battery’s
life but also allow internal moisture to evaporate.
Tip: Since the battery sits in the battery door, the door should be opened gently and slowly
so that the battery does not fall out.
