I have one as well, never have been able to find out much though. Yes, the batteries attach across the main output. Somewhere inside there is a voltage adjustment that you set according to battery specs. A switch on the back labeled float (normal position) and equalize (highr charge voltage, to equalize the batts)... I have also been told there is a function for outputting a beep to the audio to indicate loss of mains... but can't verify any of this. It doesn't appear in any of my manuals... So mine sits dormant, and I use a Xantrex C-35 and solar array... mains go and washing machine relay un-latches to engagde batts.... hillbilly-hombrew kind of thing!
Did you ever locate the manual for the S-1323A Deviation Meter / Sinadder? I never heard back...
