Notices

The Unitech MR650 is equipped with a Lithium-Ion battery pack, however as a result

of storage it’s possible that the unit will not power-on due to battery discharge. If this

occurs, connect the MR650 to the power adapter and plug into a standard electrical

outlet. Recharge the unit for 22 hours in order to fully charge its backup battery.

The battery pack can power the MR650 for approximately 2 hours (depending upon

hardware conguration and limited backlight), and backup data will remain for 3 days in

the absence of external power.

Battery Charge Notice

It is important to consider the environment temperature whenever you are charging

the Lithium-Ion battery pack. The process is most efcient where the temperature

is average or slightly cooler. It is essential that you charge the batteries within the

specied range of -5°C to 50°C. Charging batteries outside of the specied range could

damage the batteries and shorten their charging life cycle.

Storage and Safety Notice

Although charged Lithium-Ion batteries may be left unused for several months, their

capacity may deplete due to build up of internal resistance. If this occurs, the battery

will require recharging prior to use. Lithium-Ion batteries may be stored at temperatures

between-20°C to 60°C, however they may deplete more rapidly at the high end of this

range. It is recommended batteries are stored within normal room temperature ranges.
