6 Maintenance
6.1 General maintenance procedures
The performance and safety of the instrument will be maintained if the f ollowing recommendations for care
and maintenance are observed:
1. It is recommended that the instrument go through at least one annual service, to ensure that the
acoustical, electrical, and mechanical properties are correct. This should be carried out by an
authorized repairer to guarantee proper service and repair.
2. Observe that no damage is present to the insulation of the mains cable or the connectors and that it
is not exposed to any kind of mechanical load that could involve damage.
3. To ensure that the reliability of the instrument is maintained, we recommend that the operator at
short intervals, f or instance once a day, performs a test on a person with known data. This person
could be the operator. For OAE testing, a daily probe integrity test is recommended to confirm the
probe is functioning properly before testing on patients.
4. If the surface of the instrument or parts of it is contaminated, it can be cleaned using a soft cloth
moistened with a mild solution of water and detergent or similar. Always disconnect the mains power
adaptor during the cleaning process and be careful that no f luid enters the inside of the instrument or
accessories.
5. Af ter each patient examination, ensure that there has been no contamination to the parts touching
the patient. General precautions must be observed to avoid cross-contamination of disease f rom one
patient to another. Water should be used for frequent cleaning, but in the case of severe
contamination it may be necessary to use a disinfectant.
