General precautions and warnings
35
For the external components, please observe the following:
• Your audio processor (including FineTuner and coil) does not require regular maintenance
by clinic personnel or other experts.
• The defined operating temperature range is b0 °C and +50 °C for the audio
processor (including FineTuner and coil). Normally, when the audio processor is worn on
the body, natural body heat helps maintain this temperature range.
• Do not leave the audio processor or FineTuner in direct sunlight (especially inside a car).
• If you ever experience loud or uncomfortable sounds, please remove your coil and audio
processor immediately: this will stop stimulation at once.
• Do not use the audio processor or FineTuner of another cochlear implant user. Your audio
processor and FineTuner have been adjusted to your individual needs. Using another
audio processor may cause painful or uncomfortable stimulation.
• Avoid getting your audio processor or FineTuner wet as this may impair its function.
Always remove and switch off the external parts of your implant system and keep them
in a dry place before bathing, showering or engaging in other water-related activities.
• If the external parts become wet, switch off your audio processor as quickly as possible,
remove the batteries from the battery pack, unplug the battery pack from the control
unit, and gently wipe all external parts dry, using a soft absorbent cloth. Then put
the audio processor in the supplied drying kit to allow the audio processor to dry out
(preferably overnight). If in doubt, repeat the drying process. If the FineTuner becomes
wet, wipe it off with a dry tissue.
• Take care of the external components of your/your child’s MED-EL Cochlear Implant
System. They should not be dropped or subjected to dangerous areas (e.g. machines or
high voltage) which could result in damage to the components.
• Do not use the audio processor and the FineTuner in environments where radio frequency
(RF) transmissions are prohibited.
• Do not try to shape the earhook with hot air.
• Do not use your audio processor in the vicinity of strong ionising radiation (e.g. x-ray
machines) or electromagnetic fields (e.g. MRI machines).
• Do not modify the housing, the electronics or any other parts of your audio processor in
any way.
• Never place the coil or a magnet on the SONNET control unit. It is even more important
to follow this guideline when you are using a SONNETeas. The SONNETeas contains
elements which are sensitive to magnets and might be permanently damaged by strong
magnetic fields.
Children shall be instructed not to swallow or put any components of their MED-EL
Cochlear Implant System into their mouths or to play with any components. In young
children the battery pack cover lock must always be turned clockwise into the locked position
(see Fig. 7-2) once the cover has been moved completely over the frame to prevent the child
from disassembling the audio processor.
