Unitech MT380 Chapter 4 Power System

Chapter 4Power System

The MT380 is equipped with a Lithium-Ion battery pack. The MT380 may not power

on after long storage periods without an external power adapter, due to battery

discharge. In this case, connect the MT380 to the power adapter and recharge the

device for about 12-hours.

NOTE: The MT380 can operate for approximately two hours (depending on the hardware conguration and

backlight usage) or can store data for three days without external power. Operating the MT380’s backlight

screen at 100 percent brightness, and using the ngerprint utility reader consumes the most power.

Therefore, when the 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.

This status icon appears on the

MT380’s taskbar indicating low or very

low battery status. The MT380 will enter

suspend mode when the battery level

reaches low status, and the MT380

will enter sleep mode when the battery

level reaches very low status. There is

a 12-hour time window to recharge the

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 → Settings → Control Panel → Power

When there is no external power, and the backup battery icon appears in the system

tray, you should immediately backup the data from the MT380 or risk losing the data.

CAUTION! Immediately backup the MT380’s data or risk losing everything when there

is no external power, and the backup battery icon appears in the

system tray.
