As I keep getting asked the same questions 
regarding AV-TS R6 battery charge status indicators, I'm putting this to 
print.  Please save this email for reference 
purposes.
 
The charge 
status indicator definitions are as follows:
WinCE 2.12
 
"Charging"  indicates that AC power is 
present and the battery is being charged.  There is no indication on the 
screen as to how much charge is on the battery.
 
"Low" indicates that the unit is running on battery power and 
no AC is present.  Currently WinCE 2.12 will only show "low" regardless of 
the state of the battery charge.  At present software revisions (4.1.11), it is only useful as an indicator 
that AC is not present and the battery is the power 
source.
 
"High" indicates that the battery is 
disconnected from the unit (or not present), but obviously AC is present 
otherwise the unit wouldn't power up.
 
The only indicator that is working correctly is the 
"Charging" indicator.  The definitions above at least give you some idea as 
to what is really happening in the system.
