Apple prints a '''90-132 VAC''' supply for this display and no 220-240 V figure, so this volume documents the domestic unit only.

The Specifications chapter also prints '''full monitor timings''' (back porch, sync width, front porch, dot clock and line/frame periods) for 640 x 480 at 60 and 66.67 Hz and for 800 x 600 at 60 and 72 Hz. Those tables are the citable source for this display's timing, and they are reproduced nowhere else on this wiki.

== Contents ==
* '''Basics''' - Overview, '''Repair Issues: 832x624 Resolution''' (pdf pp. 3-9)
* '''Specifications''' - Characteristics, Controls and Ports, Physical and Electrical, Environmental (pdf pp. 12-20)
* '''Troubleshooting''' - General, symptom charts for No Raster, Geometry and Video (pdf pp. 22-26)
* '''Adjustments''' - Brightness and Contrast, Geometry (pdf pp. 28-34)

== What this manual does not contain ==
'''No Take Apart chapter and no Exploded View.''' Apple's strategy for this display was exchange, so there is no disassembly order at all, no parts list, no schematic, no component values and no fuse information. The Adjustments chapter covers only the user-accessible controls behind the front door.

A CRT display holds a lethal charge on the anode after the mains is removed. Follow [[CRT Discharge Procedure]] before working inside one.
