This maintenance manual is intended to be used by a trained maintenance technician or
engineer, with experience of electronic and digital circuitry, computers and
electromechanical design. The level of information is based on the maintenance
philosophy of Kongsberg Maritime: The onboard technical personnel shall, with the
help of the documentation and the system’s built-in test functions, be able to identify
malfunctions, locate the fault, and replace major parts, modules and components on the
“Line Replaceable Unit” (LRU) level. He/she will however not attempt to repair the
LRUs.
