Charging the Backup Battery for the First Time
MT380 is equipped with a Lithium-Ion battery pack. After long storage periods, the unit may not power-
on without an external power adapter due to battery discharge. In this case, connect MT380 to the
power adapter and recharge the unit for about 12 hours to fully charge the battery.
NOTE:
MT380 can operate for approximately two hours (depending on the hardware configu-
ration and backlight usage) or can store data for three days without external power.
Operating MT380’s backlight screen at 100 percent brightness, and using the finger-
print utility reader consumes the most power. Therefore, when MT380 is disconnected
from it’s external power source it will enter into sleep mode, which automatically turns
off the backlight. Tapping the touch-screen will set the backlight screen to minimum
brightness, saving battery power.
Checking the Battery Status
This status icon appears on MT380’s taskbar
indicating low or very low battery status. MT380
will enter suspend mode when the battery level
reaches low status, and MT380 will enter sleep
mode when the battery level reaches very low sta-
tus. There is a 12 hour time window to recharge
MT380, but after more than 12-hours there is a
strong risk of losing all the data on the device’s
internal memory.
This icon appears in the taskbar when the
backup battery is low and the backup battery
should be recharged as soon as possible.
Check the Power Properties by tapping o
Settings o Control Panel o double-tap Power .
CAUTION! Immediately backup MT380’s data or risk losing everything when
there is no external power, and the backup battery icon
appears in
the system tray.
