While on the CTA bus with nothing else to do, I started swapping battery combinations on my 48, and looking at the relative battery status (done by pressing [ON][D] and then [G]). These are my findings... 1) I think "ESD" means "Electro-Static Discharge". 2) "210V" is not "210 volts", but is the VOLTAGE AT PORTS 2, 1, & 0 (respectively) and that a bar under that particular digit indicates the battery status of that port. Note: I don't know about HP or CMT ram cards, but EPSON ram cards have a "Vbb" pin that is the ram card's battery voltage level. 3) When I have a fresh bunch of batteries in the 48, the battery status screen shows this... ESD 210V 210V || || When I have an old, somewhat dead bunch of batteries in the 48, I got this... ESD 210V 210V | | With fresh AAA's and a ram card (port 1) with a lithium battery installed I got this... ESD 210V 210V | | With fresh AAA's and a ram card (port 1) with the lithium battery removed, I got this... ESD 210V 210V || || I performed the two previous steps with the ram card in port 2, and saw the same results. Theory: The bars mean nothing for ports 1 and 2 if no card is in that relative slot. If a bar appears under a port digit, then the battery level for that port is low. Question: Why is there a pair of "210V" objects on the screen? Sincerely, EUG <u46837@uicvm>
