Step 9.
Turning off the hearing system
You can turn off your hearing system by opening the
battery compartment (Fig. 9).
Step 10.
Changing the battery
Before the battery is completely empty, your hearing
system will indicate to you that the battery soon needs
to be changed with an acoustic signal. Once this
happens, you have about 30 minutes (in some cases
longer) to change the battery. The battery warning
signal is repeated every half hour. We recommend that
you always keep a spare battery on hand.
