Hi George!
I looks one of these days I have to send you at least a home made cake from Italy! In the meantime if you re thinking to travel in my area 'Ravenna' please stop and accept my invitation for dinner!

It looks almost all the menus does not respond as expected.
Let's start with a simple one like DISPLAY
I have manual version 4 released by J R Stuart
Theatre: July 1994
On page 16 it looks the system, if interrogated during Standby, has to display 4 data
Example is:
2.2
P1.81
d1.2
441b
All I have is 5.040. Arrow keys are making no effects.
The bigger issue is I am not able to access to menu system as indicated in page 18 where using the W and E arrows the following menus must be available.
Tilt
Bass
Phase
Balance
Axis
W and E arrows makes no effect at all.
