Before use, please remove the plastic protective wrapping on each of the AAA batteries included with the Battery-Square.
As with most electronic devices, the batteries included with the Battery-Square are not shipped fully charged. For best performance we recommend that you fully charge the batteries before use. For fast charging, you can use a standard NiMH battery charger to charge the AAA batteries separately and then reinstall into the Battery-Square.
The Battery-Square has an On/Off switch on the side. We recommend that when the Battery-Square is not in use that you turn it off to prevent the Square from discharging the batteries.
When installing the three (3) AAA batteries into the Battery-Square, pay close attention to the polarity indicated on the PCB board by the "+" and "-" symbols.
