Enable = The transmitter will accept a new sensor only if it has the
same Part No. (=Dräger Order No.) as the old sensor and
thus the same sensor type.
Disable = The transmitter will accept other sensor types. In this case,
the transmitter uses the default settings for the new sensor,
which means that the transmitter configuration will be
changed.
