E)(PIITNATION OF DIAGRAM
Type numbers of transistors and IC'shavebeen
indicated on the diagramin those cases
where the
typenumber
is unambiguousfor the positionof the
componentin a circuitry - e.g.TR20/BC5578.
If the positionnumber
is followedby anasteriskthe
sparepart number must be used becausethis
componenthasbeenexpecially"selected
- e.g.
TR102*.
System of Co-ordinates
The largest PC-boards
havebeenprovided with a co-
ordinate system.The componentson thesePC-boards
are provided with a grid referenceon the diagram
indicating in what gnd they are positionedon the PG
board (smaller typing than position numbers - e.g.
B3).
Wiring C.onnections
The wiring connections
on the diagram are
assembled
in "bundles".The individual wires are
codedto indicateto where they are leading.
