Computer unit on radio panel (newbie!)

[Guest Dave92]

Hi all,I am just starting to get used to the amazing 737-200 (after spending the majority of my FS career in something with an FMC!). My question is, I can see a computer-type unit in the top-right of the upper radio stack window. However I cannot get it to work. The screen just stays blank no matter what buttons I press and what mode I have it in.Does anyone know what I'm doing wrong, or do I need additional software to get this unit to work?Thanks for reading, help appreciated.Dave

You need power on one of the main busses before the PDCS will work.Remember that all power sources have to be connected to their respective busses manually in the -200RegardsBob ScottATP IMEL Gulfstream II-III-IV-VSantiago de Chile
