in the immobilizer applet window.
This button is available only if the immobilizer applet is started. Authentication is not re-
quired but without a proper authentication, only limited or even no memory content can
be shown (depending on the security configuration of the transponder).
As soon as the window is opened, the transponder is contacted and all pages which are
currently visible on the screen (in the main area) are read from the transponder. This is
done continuously several times per second until the window is closed or the immobilizer
applet is stopped.
