Use only fuses having the same rating and the same response
behavior as the one being replaced.
9.3 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.
9.4 Repairing the Detector

tire detector or individual parts.
evaluation unit is turned off and disconnected from mains
