8-2. This section contains backdating changes which make
this manual applicable to earlier instruments. Where possi-
ble, backdating changes have been integrated into the
manual text, parts list and schematic diagrams. Changes
that are too long or otherwise impractical to integrate into
the manual are covered in this section. Backdating changes
included in this section are referenced by a numbered delta

which appears in the text, parts list and schematic
diagrams. The number indicates the number of the corre-
sponding backdating change. Make all backdating changes
that apply to your instrument.
