When adjusting the dimming settings, use the channels carefully to get the desired lighting effect. For maintenance, keep it in a dry place and clean it gently with a soft cloth from time to time. Avoid exposing it to water or extreme temperatures. If you notice any issues with the plug or the dimming function, stop using it immediately and contact customer support.
