4 Care and 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:
It is recommended to let the instrument go through at least one annual evaluation, to ensure that the
acoustical, electrical and mechanical properties are correct. This should be made by an experienced
workshop in order to guarantee proper service and repair.
No parts of the equipment can be serviced or maintained while in use with the patient.
Before the connection to the mains, be sure that the local mains voltage corresponds to the voltage
labelled on the instrument.
Observe that no damage is present on the insulation of the mains cable or the connectors and that it is
not exposed to any kind of mechanical load, which could involve damage.
For maximum electrical safety, turn off the power from a mains powered instrument when it is left unused.
Do not place the instrument next to a heat source of any kind, and allow sufficient space around the
instrument to ensure proper ventilation.
To ensure the reliability of the instrument, periodic biological measurements should be performed on a
person with known data. This person could be the operator him/herself.
If the surface of the instrument or parts of it is dirty, it can be cleaned using a soft cloth moistened with a
mild solution of water and dish washing cleaner or similar. The use of organic solvents and aromatic oils
must be avoided. Always disconnect the mains plug during the cleaning process, and be careful that no
fluid is entering the inside of the instrument or the accessories.
After each examination of a patient, proper cleaning must ensure that there is no contamination on the
parts in connection with patients. General precautions must be observed to prevent transmission of
disease from one patient to another. If the ear cushions or ear tips are contaminated, it is strongly
recommended to remove them from the transducer before they are cleaned. Frequent cleaning using
water may be used, but periodic use of a mild disinfectant may also be used. The use of organic solvents
and aromatic oils must be avoided.
Great care should be exercised by the handling of earphones and other transducers, as mechanical
shock may cause change of calibration.
