Schematic Diagrams

8-13. Symbols are used on PC boards to aid in identifying pin numbers, diode elements, etc.,

as follows:

AORO

IDENTIFIES:

Pin 1 of dip and flat-pack IC’s.

Tab of TO CASES.

+ side of electrolytic capacitors.

Pin 1 of resistor packs.

Cathode of diodes.

Section I of dip switches.

8-14. ASSEMBLY LOCATIONS AND COMPONENT LOCATORS

6-15. Figures in this section show the front, rear, and top views of the 5328A. The front and rear

views shows reference designators of the front and rear panel controls, connectors, and indi-

cators. The top view shows asssembly locations. Component locators for each printed-circuit

assembly are located next to the schematics.

8-16. FACTORY SELECTED COMPONENTS

8-17. Factory sleeted parts are identified by an asterisk on the schematic and in the parts list.

The nominal value is shown on the schematics and is listed in the table of replaceable parts. A

table-format summary on the schematic indexes factory selected parts by reference designator,

describes what they are selected for and the range of normal values.
