[volt-nuts] Datron 4700 manual and options

[Fred]

Today a friend gave me a Datron 4700. It looks like new. It is stored 
(working)  for many years in the cal lab he works. He was allowed to 
take it home (for me, in return I will repair his SA), He plugged it in, 
Fail 1 on the display followed by a sound and a smell.
I opened it but nothing looks burned.

I can not find a service manual, does someone has one ?

On the back the label shows no options but if he remembers it well it 
should have all or at least most  options. All slots are filled with 
pcb's. The "box" in the left upper corner is full and there is a very 
small pcb next to it. There is not much room left. Just enough to store 
a small multimeter between the huge transformer and that box.
