CHAPTER THREE - PL3000 BASICS
47
On AC
When the PL3000 is docked in its cradle, -
assuming that the device cradle is plugged into mains
socket - the power indicator shows both battery
charging status and that the PL3000 is on AC. (For
more information, see the section ‘PL3000 is being
charged’ on page 13.)
An unlit power indicator is a sign that the PL3000 is
not running on AC, when it is in the desktop charger.
Similarly, if the indicator is flashing on and off the
PL3000 is not running on AC, although it is docked in
the desktop charger. Only steady light is an indication
of being on AC together with the up-and-running system.
On Battery
The power indicator indicates the battery status
when the PL3000 is running on battery. An unlit power
indicator shows that you need not care about battery
performance (service hours). However, when the
battery is running low, the LED starts flashing yellow
light. You can still use your PL3000, but be aware that
the operating time being left is short.
After having flashed yellow for a while the power
indicator starts flashing red light and the Windows CE
displays a warning message ‘Main Batteries Very Low’
on the display. Discharging of the battery has reached
the point when your device may power down itself any
moment now. If you close the warning window, you can
still operate your device; although it is risky business to
do that. When the system makes a decision that the
battery is not able to power the device any longer, the
screen goes blank; the red LED stops flickering and red
light stays on. Apart from the red light of the power indicator, the rest of the device
is dead.
You can replace the dead or low battery on the fly, if you have a charged
spare battery available; see the section ‘Backup Battery’ on the preceding page.
Otherwise, you may charge your PL3000 by docking it into the desktop charger.
