Schematic for Compal function board LS-4498P, part of the KAL90 project, revision 1.0, in a 24 KB PDF. Compal uses LS numbers for auxiliary boards, and a function board typically carries buttons, indicators or media keys. The short document is handy for verifying switch wiring, LED resistors and the flex connector pinout to the mainboard. Match the LS number printed on the board before use, and refer to the KAL90 main board schematic for circuits beyond this daughterboard.
