Securing the Pod and Probe to the Screener
To make it easy to carry the Screener from patient to patient, you can attach the Pod to the
Screener body, and the Probe (without an eartip attached) to the Pod. You can leave the
Pod attached to the Screener while running tests.
Remove the eartip before attaching the Probe to the Pod.
To attach the Pod to the Screener, align the “button” on the under surface of the Pod with
the circular opening in the Screener
into the keyed opening on the Screener. To remove the Pod, slide it forward and pull it out
of the circular opening
snugly. It is not necessary to force the Probe into a secure position.
