If the test is confirmed to be correct, use it under the guidance of a professional electrician. 4. 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). 5. When using wireless electronic products, care should be taken to avoid metal masks, large electronic devices, electromagnetic fields, etc., which have strong interference sources, to avoid remote control and short receiving distance or to work normally. 6. 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.
