• Hearing aids may fail suddenly without prior
warning (e.g. in case of a defect or an empty
battery), particularly in situations where you’re
required to hear acoustic warning signals, e.g.
in trac.
• Be aware that some sounds may sound
dierent when you’re using the hearing aids.
Keep this in mind when you need to be aware
of your surroundings. You should adjust to this
over time.
