28.6 System Fault Finding Guide
The primary means of system fault finding is by reference to the fault codes that are reported by Slave and
Audio Control Units. The engineer obviously must be appropriately trained so as to be familiar with both the
system architecture and that of the particular installation in order to use the information effectively. Some
diagnostic tools are built into the system to further aid fault finding, see Section “25 Diagnostic Tools” on
page 118.
The following tables describe the fault codes for VAR8 and its variants.
