Then , after the learning button 2 ~ 3 is pressed , the indicator light will automatically go out . Release the learning button and press any button on the remote control . The indicator light flashes 5 times , indicating that the learning is successful . Note : This controller can learn 16 remote codes of fixed code and learning code , such as fixed code and any button . If it exceeds , it will clear the earliest remote control . Clear method : Press and hold the learning button for about 8 seconds . The indicator will turn off and return to light . Package Includes : 3 piece Remote Control Switch 1 piece Receiver Note : 1 . Do not operate with power . The power should be turned off for operation , and the power is used after the test is confirmed to be correct . 2 . When the voltage of the remote control is insufficient , please change the battery in time ( the remote control distance becomes closer when the remote control battery voltage is insufficient ). 3 , when using wireless electronic products should pay attention to avoid metal masks , large electronic equipment , electromagnetic fields , etc . have a strong interference source , to avoid remote control and receiving distance is short or can not work properly . 4 . Do not use this electronic product abnormally . Abnormal use will reduce product performance and longevity . In severe cases , damage to the product will also pose a safety hazard .
