behavior as the one being replaced.

Replacing the Evaluation Unit
When replacing the evaluation unit, we recommend that you take
the plug-in EE-Prom from the old device and insert it into the new
one (see Figure 39). All parameters and settings will be retained.
The EE-Prom has to be protected against destruction by electro-
static charge.

tire detector or individual parts.
