Using your Mi - Light 4 - Zone LED Remote Controller is a breeze. First, insert two AAA batteries into the back of the remote (batteries are not included). Point the remote towards the RGBW LED Controller Box that's connected to your non - addressable LED strips. Then, use the touch - sensing buttons to change the color and brightness of the LED strips. You can also control the power of the whole lighting system, select pre - set modes, or adjust the speed. Remember to keep the remote within about 30m (almost 100ft) of the control box for it to work properly. When not in use, remove the batteries to prevent any possible leakage. Clean the remote with a dry, soft cloth to keep it in good condition.
