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?
