Care and maintenance

4.1 General maintenance procedures
It is recommended that routine check procedures are carried out weekly in full on all equipment in use.
Checks 1-8 outlined below should be carried out on the equipment on each day of use.
The purpose of routine checking is to ensure that the equipment is working properly, that its calibration has
not noticeably changed, and that its transducers and connections are free from any defect that might
adversely affect the test result. The checking procedures should be carried out with the instrument set up in
its usual working situation without being connected to a patient.
1. Clean and examine the instrument and all accessories.
2. Check probe tube, plugs, main leads and accessory leads for signs of wear or damage. Damaged or
badly worn parts should be replaced.
3. On battery-powered equipment, check battery state using the manufacturer's specified method. Switch
on equipment and leave for the recommended warm-up time. If no warm-up period is stated, allow 5
minutes for the circuits to stabilize. Carry out any setting-up adjustments as specified.
4. Check that the probe serial number is correct for use with the instrument.
5. Check that the instruments's output is approximately correct by conducting a simplified test on a
known test subject with known hearing; check for any change.
6. Listen at low levels for any sign of noise, hum, or unwanted sounds from the device.
7. The instrument has been designed to provide many years of reliable service, but annual calibration is
recommended to ensure ongoing accuracy of the transducers.
8. If the instrument or transducers have been exposed to damage (dropped or similar), please ensure
that calibration has been maintained. Recalibration may be required.
9. The calibration procedure is available in the service manual.
Please note: Great care should be exercised in the handling of probes and other transducers, as mechanical
shock may cause a change in calibration.
4.2 How to clean Interacoustics products
If the surface of the instrument or parts of it are contaminated, they can be cleaned using a soft cloth
moistened with a mild solution of water and dish-washing cleaner or similar (e.g. normal hospital
bactericides). The use of aggressive solvents and aromatic oils must be avoided. Always disconnect the
USB cable during the cleaning process, and be careful that no fluid enters the inside of the instrument or the
accessories.
Before cleaning always switch off and disconnect from power
Use a soft cloth lightly dampened with cleaning solution to clean all exposed surfaces
Do not allow liquid to come in contact with the metal parts inside the probe
Do not autoclave, sterilize or immerse the instrument or accessory in any fluid
Do not use hard or pointed objects to clean any part of the instrument or accessory
Do not let parts that have been in contact with fluids dry before cleaning
Rubber eartips are single use components
Ensure isopropyl alcohol does not come into contact with any screens on the instruments
Ensure that isopropyl alcohol does not come into contact with any silicone tubes or rubber parts
