About This ManualiiiBattery NoticesThe MT680-AMWTAG is equipped with a Lithium-Ion battery. But, after extended storage periods, the MT680-AMWTAG may not start without an external power source due to battery discharge. In this case, connect the MT680-AMWTAG to the power cable and recharge the MT680-AMWTAG for about 12 hours to charge the battery to full capacity.The battery supplies operational power to the MT680-AMWTAG for approximately two hours (depending on hardware configuration and with limited backlight use) or provides backup datafor three days when there is no external power source.Battery Charge NoticeIt is important to consider the environmental temperature whenever the Lithium-Ion battery is charged, which is most efficient at room temperature or in a slightly cooler environment. It is essential that batteries are charged within the range of 0°C to 45°C (32ºF to 113ºF). Charging batteries outside of the specified range could damage the batteries and shorten their charging life cycle.Storage and Safety NoticeAlthough charged Lithium-Ion batteries may be left unused for several months, their capacity may deplete due to build up of internal resistance. If this happens they will require recharging prior to use. Lithium-Ion batteries may store at temperatures between -20°C to 60°C (-4ºF to 140ºF), however they may deplete more rapidly at the warmer end of this temperature range. It is also recommended to store batteries at room temperature.WarrantyThe following items are covered under Unitech Limited Warranty:• MT680-AMWTAG Versatile Multi-Function Terminal. – 1-year limited warranty.• Cables – three-month limited warranty.• Backup Battery – three-month limited warranty.

21Chapter 4Power SystemCharging the Battery for the First TimeThe MT680-AMWTAG is equipped with a Lithium-Ion battery. The MT680-AMWTAG may not power on after long storage periods without an external power adapter, due to battery discharge. In this case, connect the MT680-AMWTAG to the power adapter and recharge the device for about 12 hours.NOTE: The MT680-AMWTAG can operate for approximately two hours (depending on the hard-ware configuration and backlight usage) or can store data for 24 hours without external power. Operating the MT680-AMWTAG’s backlight screen at 100 percent brightness consumes the most power. Therefore, when the MT680-AMWTAG disconnects from its external power sourceit 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 StatusCheck the Power Properties by tapping Start → Settings → Control Panel → double-tap Power.This status icon appears on the MT680-AMWTAG’s task-bar indicating the low battery status. The MT680-AMWTAG will enter suspend mode when the battery level reaches Low status, and the MT680-AMWTAG will enter sleep mode when the battery level reaches Very Low status. There is a 12 hour time window to recharge the MT680-AMWTAG, but after this time period there is a strong risk of losing all the MT680-AMWTAG's internal memoryThis icon appears in the taskbar when the bat-tery is Very Low and the battery should be recharged as soon as possible.CAUTION! Immediately backup the MT680-AMWTAG’s data or risk losing everything when there is no external power, and the Main Batteries Very Low warning window appears.
