Archive of 219 KB for the Apple 820-2306 IR board, the small infrared receiver daughterboard. No revision is given, so confirm the number printed on the part before use. The contents are not listed but likely include a schematic, possibly with layout data. Use it to check the supply voltage reaching the IR sensor, follow its output signal and any indicator LED lines, and test continuity through the connector to the logic board when a remote control or sleep light stops responding.
