Modifications

2.2.1 Updating the service manual
All modifications and/or supplements to the Service Manual
are published by means of Service Information bulletins.
Each Service Information is numbered:
VR 01 - 01 GB
A Service Information bulletin consists of a front page which,
if needed, is followed by supplementary and/or replacement
sheets.
Replacement sheets should replace existing sheets in the
Service Manual. These sheets are identified by an additional
letter after the page number.
Example: Page 5-1a replaces page 5-1 in the Service
Manual.
Supplementary sheets should be inserted between existing
sheets in the Service Manual. These sheets are identified by
an additional figure after the page number.
Example: Page 5-1-1 should be inserted after page 5-1.

All important parts of the set (such as the tape deck, the
printed circuits and modules) are equiped with a sticker.
Those stickers provide a number of important information.
