Specs and Function
Column Page refers to the page of the schematics called "NOZOMI-1 EXT SDV LOGIC SCHEMATICS. NZM1H-1 VER 1.31 DEC/04/2008". Part Number and nominal current are taken from this schematics, too. F23 is missing in the schematics, but clearly marked in the silk screen on the PCB. It seems like R174 in the schematics was replaced by F8 and the old F8 with F23. The circuit around J11 (status LED, camera USB to the display unit) seems to had a redesign after the schematics was created - F14 connects to pin 29 on the board, while this pin is floating in the schematics.
