[Elecraft] OT : signal genarator Marconi 2018A

[luc]

Just a little bit of topic :
On an Hamfest on saturday, I've purchased a nice signal generator Marconi
Instuments 2018A, of course, without manual.
My question : how do I unlock the "Protected Functions" to change, for
instance, the various step sizes (RF level, mod level, frequency offset) ?
The factory defaults to 1 (µV, % and  kHz), not very convenient for aligning
analogic devices !
Thanks to help me, off or on list.
