1.1 BATTERY
1.1.1 MAIN BATTERY
The mobile computer is powered by a rechargeable 3.7 V/1800 mAh Li-ion battery pack.
When the mobile computer is turned on, it takes approx. 4 hours to charge it to full from
the power adaptor (using RS-232 cable or cradle) or approx. 5 hours from the USB cable
(at 500 mA).
For power-saving purpose, always turn off the backlight while working in a well-lit area.
When the backlight is on for extended periods of time, the main battery will become low
sooner than expected.
The smart battery icon on the LCD screen shows the status of power consumption. There
are two ways to monitor a low battery charge or discharged battery from the screen.
Examine the level of the 4-bar battery icon
Monitor voltage level (see 3.5 Power)
