Table 6-1. Schematic Diagram Notes
1. denotes front-panel marking.
2.
denotes rear-panel marking.
3. Complete reference designator consists of component reference designator prefixed with assembly number
(e.g.: A2R14).
4. Resistor values are in ohms. Unless otherwise noted, resistors are either 1/4W, 5% or 1/8W, 1%. Parts list provides
power rating and tolerance for all resistors.
5. Unless otherwise noted, capacitor values are in microfarads.
6. Square p.c. pads indicate one of the following:
a. pin 1 of an integrated circuit.
b. the cathode of a diode or emitter of a transistor.
c. the positive end of a polarized capacitor.
7. In schematic symbols drawn to show right-to-left signal flow, blocks of information are still read left to right. For
example:
indicates shift away from control block (normally down and to right). indicates shift toward control block
(normally up and to left).
8.
indicates multiple paths represented by only one line. Reference designators with pin
numbers indicate destination, or signal names identify individual paths. Numbers
indicate number of paths represented by the line.
9. Inter-board commons have letter identifications (e.g. : ); commons existing on a single assembly have number
identifications (e.g.: ).
10. For single in-line resistor packages, pin 1 is marked with a dot. For dual in-line integrated circuit packages, pin 1 is
either marked with a dot, or pin 1 is to the left (as viewed from top) of indication at end of integrated circuit
package. e.g.:
