TROUBLESHOOTING PROCEDURES

The troubleshooting and repair philosophy for the MTR2000 station and ancillary equipment is one of Field Re-
placeable Unit (FRU) substitution. The station comprises self-contained FRUs which, when determined to be
faulty, may be replaced with known good FRUs to quickly bring the station back to normal operation. The faulty
FRU must then be shipped to the Motorola System Support Center repair depot for further troubleshooting and
repair to the component level.
Because the station is computer-controlled and employs state-of-the-art digital signal processing techniques,
many of the troubleshooting procedures require the use of the Radio Service Software (RSS) application. The RSS
™
is run on a PC (or compatible) with Microsoft Windows 3.1 or Windows 95, and RS-232 communication port ca-
pabilities. The RSS allows the technician to run diagnostics, and set up the equipment for various audio and RF
tests. Complete details on RSS operation are provided within the RSS application via Online Help facilities. The
RSS Startup Manual (68P81096E15) provides complete details on installing and starting the RSS program.
