Care and Maintenance
Remove the unit’s batteries before cleaning!
If the surface of the instrument or parts of it is contaminated, it can be cleaned using a
soft cloth slightly damp with a mild solution of water and dish washing cleaner or
similar. The use of organic solvents and aromatic oils must be avoided.
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 are severely contaminated, it is strongly recommended to remove them
from the transducer before they are cleaned with a disinfectant. The use of organic
solvents and aromatic oils must be avoided.
Always disconnect the unit’s energy source before the cleaning process, and be careful
that no fluid enters the inside of the instrument or the accessories; no alcohol or harsh
chemicals should be used.
Leave the headset connected to the audiometer permanently to minimize straining the
connections. Should it be necessary to unplug the headset, always grasp the barrel of
the connecting plugs and pull straight out- never pull on the cords.
Avoid dropping the earphones or snapping them together. This could affect the
calibration accuracy.
Store the audiometer and headset in the carrying case at the end of each day to
minimize dust collection.
