Setting SQUAWK code

Hi,
I'm running Jeehell on FSX and want to set the SQUAWK code / mode.
At themoment, I don't have an external TCAS hardware unit. How can I do realize it?

best regards
Frank

you can simply use the MCDU Menu / TCAS page to set the squawk.

Regards,
Stephan

Thanks Stephan, it seems the manual at the end on side 126 seems outdated:
"Let's first enter the transponder code (via FS)".

Thanks for your help & best regards
Frank
