[Premium-Rx] AEG E-1800A Information?

[acyg]

Greetings to all,

I have recently acquired an AEG E-1800A. An expensive but very good
receiver.
I am still studying its design and testing its parameters.
A very well designed set that I am sure is packed with features and
technical setup functionality that is not immediately described in its
manuals.
Can anyone confirm this and or help me with details of any hidden second
function setup codes?

I have the operating and maintenance manuals, in German which describe the
basic 2nd function and BITE test codes.
An English operating and technical manual would also be very appreciated.

Naturally I will cover all costs and expensed.

Many thanks for reading.
