When the remote control voltage is insufficient, please change the battery in time (when the remote control battery voltage is insufficient, the remote control distance becomes close).  3. When using wireless electronic products, care should be taken to avoid metal masks, large electronic devices, electromagnetic fields, etc., which have a strong source of interference, to avoid the remote control and the receiving distance being short or unable to work properly.  4. Do not use this electronic product abnormally. Unusual use will reduce product performance and longevity. In severe cases, damage to the product will also bring hidden dangers to your safety.    Default staus: power off (can't be reset);  1. The working voltage: AC85-260V;  2. Quiescent current: 8mA;  3.
