PREVENTATIVE MAINTENANCE

To maximize the service life of your audiometer and

headset we suggest the following:

1. Dust the audiometer occasionally with a soft, dry cloth.

2. Wipe the headset cords and ear cushions occasionally

with a warm, slightly damp cloth. Ear cushions should

be removed from receivers when cleaning. Dry with a

soft cloth.

3. 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.

4. Avoid dropping the earphones or snapping them

together. This could affect the calibration accuracy.

5. Store the audiometer and headset in the carrying case

at the end of each day to minimize dust collection.
