Can't get the PDCS system to function.  Airspeed  and EPR cursors don't move when hitting engage button.  Only seem to be able to get the CRT to display the TO EPR setting correctly...all other flight mode EPR & airspeed/Mach numbers are bogus.

I believe I'm entering data correctly...however the manual refers to "Supplementary Procedures" pages for programming and operating the system.  Can't find these pages in the manuals provided.

Please advise how to get the Supplementary Procedures and get the system working correctly.

Thanks.
