3-1 DOCUMENT NOTES
These notes explain component designation and symbol use on our documentation.
Abbreviations are decoded in the Glossary.
Component designators include three items of information:
COMPONENT CLASS
--PCB NUMBER
R1126
-COMPONENT NUMBER
Component Class is symbolized by U.S. industry-standard letters, for example, U for
integrated circuit, Q for transistor, and DS for indicator. Component class letters are
so identified in the Glossary.
The Pro-One has only one PCB, so the PCB number is one in dl cases. No PCB Number
is given for chassis-mounted components. (A1 though the back-panel jacks mount
directly
to the PCB, for designation they are considered to be chassis-mounted.)
Component Numbers are sequenced according to their position on the original PCB,
When it sometimes becomes necessary to later add a component to the PCB, its
designator will usually not be in sequence. This helps identify the modification.
Signals are continued between pages as shown here. Note that the destination or
source is always given. The pointers indicate signal flow.

Connectars are drawn according to whether the pins are male or female, so the arrows
do not necessarily indicate signal flow. Zeros are slashed oply where needed to prevent
am bigul t y.

Power and ground connections for multi-device ICs are shown .on the first device in the
package, except where the first device is not presently used.
Unless otherwise indicated, resistances are in ohms and capacitances in microfarads.
