14.2 Cleaning
There are no specific requirements to sterilization or disinfection of the test device.
The device
• Remove dust using a soft brush.
• Use a soft, slightly damp cloth with a small amount of mild detergent or approved non-caustic medical grade dis-
infectant wipes to clean the unit according to local infection control regulations.
Keep the unit away from liquids. Do not allow moisture inside the unit. Moisture inside the unit can damage the instru-
ment and it may result in a risk of electrical shock to the user or patient.
Accessories
These parts are in constant contact with your patients and should therefore be kept clean.
• Headphones
Use a non-alcohol based wipe (e.g. Audiowipe) to clean the headphones between patients.
• Eartips for Insert Earphones
The eartips are disposable and therefore should not be cleaned or re-used.
• Bone oscillator
Clean the bone oscillator between patients, e.g. with a non-alcohol based antibacterial wipe, such as Audiowipes.
Disposal
There are no special requirements for the disposal of eartips, i.e. they can be discarded according to local regulations.
14.3 Calibration
Annual calibration
The audiometer, headphones, bone oscillators, and sound field speakers must be calibrated once a year by your authorized
service department.
Caution• Note that calibration has been performed only on the transducers supplied! If you wish to use any other
transducer for testing with the device, please contact your local distributor first.
