• Never put your hearing instruments or batteries in your mouth for any reason, as they
are slippery and could be swallowed by accident.
• Most hearing instruments can be supplied with a tamper-resistant battery compartment
upon request. This is strongly recommended for infants, small children, and people with
learning difficulties.
If a battery or hearing instrument is swallowed, see a doctor immediately.
• Hearing instruments may stop functioning, for instance if the battery goes dead.
You should be aware of this possibility, in particular when you are in traffic or
otherwise depend on warning sounds.
• If a battery or hearing instrument is swallowed, see a doctor immediately and call the
National Poison Center, collect (202) 625-3333.
• Never allow others to wear your hearing instruments as incorrect/wrongful usage
could cause permanent damage to their hearing.
Battery use
• Always use batteries recommended by your hearing care professional. Batteries of low
quality may leak and cause bodily harm.
• Never attempt to recharge your batteries. They may explode and cause serious injury.
• Never dispose of batteries by burning them. There is a risk that they will explode and
cause serious injury.
Dysfunction in hearing instruments
• Hearing instruments may stop functioning, for instance if the batteries have expired or
if the tubing is blocked by moisture or earwax. You should be aware of this possibility,
in particular when you are in traffic or otherwise dependent on warning sounds.
