GV60 TROUBLESHOOTING MANUAL RESPONDING TO ALARMS Remote Troubleshooting Remote on-air troubleshooting consists of monitoring the transmitter's radiated signal using an on-air monitor or via a LAN connection, and observing the status of each remote fault alarm indicator. Information obtained from these sources should enable an operator to decide whether an alarm response may be deferred to a more convenient time, an immediate corrective action must be taken, or if a standby transmitter must be enabled (if one is available).
GV60 TROUBLESHOOTING MANUAL RESPONDING TO ALARMS Electrostatic Protection The transmitter's assemblies contain semiconductor devices that are susceptible to damage from electrostatic discharge. The following precautions must be observed when handling an assembly which contains these devices. CAUTION! Electrostatic energy is produced when two insulating materials are rubbed together.

Resistor power ratings are not shown when less than 0.5 W Unidentified diodes are part number BAS21HT1 (Nautel Part # QDRS01) 24V Unidentified transient suppressors are part number 0603E SDA-TR1 (Nautel Part # QR70) Graphic and Logic Symbols The graphic symbols used on electrical schematics are in accordance with American National Standard ANSI Y32.2-1975 - Graphic Symbols for Electrical and Electronic Diagrams.
GV60 TROUBLESHOOTING MANUAL READING ELECTRICAL SCHEMATICS Unique Symbols Nautel uses unique symbols on electrical schematics to describe logic (two-state) signals. These signals differ from single-state signals or analog signals that may have multiple values. Type of Inputs and Outputs On electrical schematics, names used to describe logic (two-state) input and output signals are prefixed with a # symbol.
4.2.1. Follow the family tree branches to the block that contains the desired reference designation, and associated Nautel nomenclature (e.g., NAPA31C Power Amplifier PWB ). Note the reference designations and Nautel nomenclatures of all higher assemblies in the path. Example: A8 NAA61B RF Module Assy 1 -> A8A1 NAPA31C Power Amplifier PWB .
