Removing and refitting the main module

Caution!
-
Both models: When replacing the main module, ensure the correct module is used (the module for
XRS and SRS models are different).
-

data is transferred to a PC using EziLink before changing the battery. Back-up data must be
burned to CD ROM or DVD and supplied to the customer when the stick reader is returned. See
Backing up customer data on page 22.
