Charging the Backup Battery for the First Time
The MT650 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 the MT650 to the power adapter and
recharge the unit for about 22 hours to fully charge the battery.
NOTE:
The MT650 can operate for approximately 1 hour (depending on the
hardware configuration and backlight usage) or can store data for 6
days when there is no external power. Operating with the backlight at
100% brightness and using the finger print utility consumes more
power. Therefore, when the MT650 is disconnected from external
power, the unit will enter sleep mode and turn off the backlight. When
you tap the touch panel, the backlight is set to minimum brightness to
saving battery power.
Checking the Battery Status
If the main battery level becomes low in the course of normal use, a status icon
appears on the device taskbar indicating low or very low battery status. If
the battery level reaches low status, the device will enter suspend mode; if the
battery level reaches very low status, the device will enter deep sleep mode. In
this case, you have about 72 hours to recharge your device after which you
risk losing all data on your device's internal memory. When the backup battery
is low, an icon
appears in the Taskbar indicating that you should recharge
the backup battery as soon as possible.
