Virtual battery operation ?

Repaired a Technics SU C2000 control amplifier, which is just a preamp. An
LED displays that it is in this VBO mode.
The SU C1000 has a battery back for this, but no battery pack in the C2000
unless it is somehow hidden in the faux (poids for your bucks) heavy metal
sub frame. No monster caps either , so what is this all about ?
Just as a guess, flash memory?
