    VS300 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.
