Selectric I/O Reference Manual
Section 5
This publication is a copy of the FE Service Index. It is a val-
uable service aid to the CE who is trouble-shooting the Selectric
I/O.
Included are diagnostic flow charts which follow the sequence
of operation and point out the area of adjustment(s) required
to resolve I/O malfunctions. The numbers found in the blocks
on each chart refer to a specific adjustment or service hint
(S.H.). When additional information is required, the "Selectric"
I/O Reference Manual should be consulted.
When diagnostic charts are not effective a brief narrative and
illustration are used.
