4. Maintenance

4.1 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 Interacoustics 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.
