RCU maintenance
The RCU has been designed for maintenance
free operation except for the battery which
is discussed in Battery replacement section
on page 57.
Do not attempt to disassemble the RCU.
Disassembly will void the warranty.
Except for the battery and electronics
compartment, serviceable parts are not inside
the RCU.
If the RCU is suspected of having a fault,
please contact Siemens customer service.
When contacting Siemens, you will need to
provide the following information:
Manufacturing serial number. This is
located on the label on the side of the
battery compartment.
Software version installed in the RCU.
This is displayed in RCU Connect
maintenance tab when connected to the
RCU.
Details of any customer specific
equipment installed including radios,
modems or RCU accessories fitted.
In case of a genuine electronic failure, the
entire electronics compartment will need to
be returned to Siemens for analysis, repair
or replacement. The process to replace an
electronics compartment is described in
Electronics compartment replacement
section on page 58.
To ensure that the RCU operates reliably,
spare parts must be replaced only by trained
and certified personnel. To order spare parts
from Siemens an MLFB number is required.
For more information see the MLFB-list or
contact Siemens.
