4. Using the hearing aid
Step 10. Changing the battery
Your hearing aid will indicate with a double beep, that
the battery soon needs to be changed. You typically have
up to 30 minutes to change the battery, however this can
dier and may be considerably shorter. We recommend
that you always keep a spare battery on hand.
I To estimate the average battery life, we recommend
you track the time frame from when you start
using your haring aid to when you hear the end of
life battery tones.
