Disinfecting procedures for the probe tip
The probe tip material is highly resistant to a wide range of temperature and chemical influences. To disinfect the probe tip, perform the
following:
•
After cleaning, immerse the probe tip in a bath of 70-90% ethyl or isopropyl alcohol for 10-30 minutes contact time. When you have
disinfected the probe tip, rinse it thoroughly in regular water.
If your established infection control procedure dictates autoclaving, ensure the probe tip has not been deformed by the autoclaving process.
Ensure the sound channels are completely dry before you fit the tip back onto the probe body. If needed, use a spare probe tip.
10.1.2
Cleaning the probe body
Note: For periodic cleaning of the probe body, contact your authorized service department.
Note: The probe body contains sensitive components. Never clean the sound apertures in the probe body mechanically or with liquids. Doing so
may cause damage to the probe.
Warning: Even the slightest amount of moisture may dissolve any residual cerumen and contaminate the sensitive parts in the body of
the probe.
– Use a moist tissue with alcohol for regular surface cleaning.
No part of the ear probe should be subjected to ultrasonic cleaning solutions or machines.
10.1.3
Probe calibration
Note: Natus Medical Denmark ApS recommends that an annual calibration be performed on Alpha OAE+ and probe. Natus Medical Denmark
ApS also recommends that calibration be performed if the equipment has suffered any potential damage.
The Alpha OAE+ probe is calibrated at the factory. There may not be a full year to the next calibration date stated on the calibration
certificate.
The first time you connect the probe to Alpha OAE+ and perform a test, the calibration date will be set so that there is one year to the next
calibration.
To view the next calibration date, press Settings > System info.
Calibration frequency
The probe should be calibrated annually by authorized service personnel at an authorized workshop.
