=== What this manual does not contain ===
* A procedure for opening the case or removing the chassis.
* Any coverage of the JVC Version 2 or the Samsung set.
* The SC1224's own pages that would carry the printed numbers 3, 4, 29 and 30; the scan has the monochrome monitor's pages in those places.
* Correct values for every part. The parts list prints C703 as 100 µF where the schematic and the part number give 1000 µF, gives C961, C963 and C965 in pF where they are 1000 µF, 1000 µF and 100 µF electrolytics, and numbers the LA7830 vertical output IC as IC801 where the schematic and the theory section call it IC601.<ref name="ca3" /><ref name="ca3sch" />
