This link talks about CPOM option. Perhaps part of P rubbed off?
I read somewhere, 5V thing is just a cost saving and nothing else. From memory, I recall it's just a 3 terminal regulator inside. Perhaps that blew???

I'm stuck in a wormhole.... Hello, worms!

I recently acquired an FE 5650A 10 MHz standard. So far, I cannot get the
status indictor to lock.
This 5650A has option "CFOM" whatever that means. It appears the 5650A came
in several configurations. I do not see that option listed in the FE
manual. My other 56050A has option 20 and lets me use a single +15V supply.
It's possible that lock isn't occurring because it may need a +5V supply
like 5650A models that do NOT have option 20. I am using a +15V Dell laptop
supply that works great with the working 56050A. A status LED and 2N3906
transistor was added into the DB-9 power connector to indicate when lock is
achieved. Never a problem with the working 5650A.
Can anyone provide any information with respect to option "CFOM?"
