• Never put your hearing instrument 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.
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.
Dysfunc tion in hearing ins truments
• 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.
Active Implants
• The included case for instrument storage has a built-in magnet. If you have an
implantable device, such as pacemakers or defibrillators, the instrument case should
not be carried in a chest pocket or near to the chest.
Explosives
• The power source in your hearing instrument has insufficient energy to cause fire in
normal conditions of use. The hearing instrument has not been tested for compliance
with international standards concerning explosive atmospheres. It is recommended
not to use your hearing instruments in areas where there is a danger of explosions.
X-ray, CT, MR, PET scanning an d electrothera py
• Remove your hearing instrument for example during X-ray, CT / MR / PET scanning
electrotherapy or surgery as your hearing instruments may be damaged when exposed
to strong fields.
Power Instruments
• Special care should be exercised in selecting, fitting and using a hearing instrument
where maximum sound pressure capability exceeds 132 dB SPL (IEC 711) as there may
be risk of impairing the remaining hearing of the hearing instrument user.
