11.1.3
Probe calibration
The AccuScreen probe is calibrated at the factory prior to delivery. This is why there may not be a full year to the next cal-
ibration date stated on the calibration certificate when you receive AccuScreen.
The first time you connect the probe to AccuScreen 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, select
Settings > System info
. Before you perform the first test, the date field will be
blank.
Calibration frequency
The probe should be calibrated annually by authorised service personnel at an authorised workshop.

The ear coupler cable
11.3.1
Cleaning the ear coupler cable
Always mount the ear couplers on the ear coupler adapters before use to prevent the ear coupler adapters from coming
into contact with the patient. The ear couplers are disposable items and should be used only on one patient.
If there is a risk of cross-infection, clean the adapters. Otherwise, clean the adapters at the end of the day:
1. Disconnect the ear coupler cable from AccuScreen.
Caution
•
Never immerse the ear coupler cable in liquid.
2. Clean ear coupler cable and cable plug between each patient or if surface is visibly contaminated.
Use a sterile alcohol wipe to clean the surfaces and wait until the ear coupler cable and cable plug are completely dry.
Note
•
A sterile alcohol wipe typically contains isopropyl alcohol 70%. It is important to have the disinfectant in
contact with the surface for the time period specified by the disinfectant manufacturer to ensure its effectiveness.
