1.5 Typeplate
Every ear sensor has a unique serial number. A label with this number is located at the back
of the ear sensor.
The ear sensor is available in two variants, the CWS4-S8 and CWS4-S9. Both ear sensors use
the same electronics and have identical functionality. The only difference is the production
method.

4 Remark: The real serial number is longer than the two letters and six digits that are
displayed on the label. The number starts with "A0000ABB" but since that part is generic
for all ear sensors, this has been omitted. If the QR-code is scanned all 16 positions of
the serial number will be displayed.
