Modifications

Description of the system used for publishing
modification data and supplements to the
service manual.
All modification data and supplements to the Service Manual are
published by means of Service Information bulletins.
Each Service information has a number, for example :
VR 00 - 01 GB
A Service Information bulletin concists of a front sheet, as the case
may be followed by supplementary and/or replacement sheets.
Replacement sheets serve to replace existing sheets in the Service
Manual. These sheets are identified by an additional letter after the
page number, for example 5-1a. Page 5-1a then takes the place of
page 5-1.
Supplementary sheets are inserted between the existing sheets in
the Service Manual. These sheets can be identified by an additional
figure following the page number, for example 5-1-1.
Sheet 5-1-1 should be inserted after page 5-1.
