General Maintenance Procedures

The performance and safety of the instrument will be kept if the following recommendations for care and maintenance are
observed:
The instrument must go through at least one annual overhaul, to ensure that the acoustical, electrical and
•
mechanical properties are correct. This should be made by an authorised workshop in order to guaranty proper
service and repair as Radioear provides the necessary circuit diagrams etc. to these repair shops.
To ensure that the reliability of the instrument is kept, it is recommended that the operator at short intervals, for
•
instance once a day, perform a test on a person with known data. This person could be the operator him/herself.
After each examination of a patient, it should be ensured that there is no contamination on the parts in connection
•
with the patient. General precautions must be observed in order to avoid that disease from one patient is
conducted to others. If ear cushions or ear tips are contaminated, it is strongly recommended to remove them from
the transducer before they are cleaned. By frequent cleaning water should be used, but by severe contamination it
may be necessary to use a disinfectant. The use of organic solvents and aromatic oils must be avoided.
