The remote controller is powered with a 3V button(CR2025) battery (2 included).
Just in case the battery runs out on the remote controller, the receiver unit features a button to manually switch lighting functions or turn on/off.
For added functionality, the receiver unit can also be attached to the front I/O reset button for convenient control outside the case.
With the included adaptor, the A-RGB Controller can also control any non-DeepCool A-RGB products that have a standard 3-pin 5V A-RGB connector.
