Your BTE has a tamper-resistant,
locking battery compartment.
The lock switch is located on
the bottom of the battery door.
To lock the door, use an appropriate tool
to slide the recessed switch to the left until
it “clicks” and the orange mark is visible.
Locking the door is
not
necessary for
operation.
