Omron’s AC adapter

Omron’s own product pages for the Complete BP7900 and the Evolv BP7000 say they aren’t compatible with an AC adaptor, while the adapter’s list includes both. Check the monitor’s manual before getting an adapter for either one.
Common questions
What should I do after changing the batteries in a Braun ExactFit 3?
Braun says to always reset the date and time after fitting new batteries in the ExactFit 3 BUA6150, so its readings are stored with the right date and time.
