1. When the emitter is unable to remotely control the receiver ,please check whether the switch baterise are in good control.whether they are fixed properly and whether they run out of use. 2. when the emitter is unable to remotely control the receiver ,please check whether there is other remote control products around the space and check whether the keys are pressed down,because same nature of remote control product may cauxe interfercnce with each other resulting in poorreceiving effect.Taking away such articles will normalize the remote control function .(the infrated remote controller are not included). 3. Please use this product under applicable voltage.Too low voltage will lead to failure of the remote controller to work (Please refer to the product label for the voltage range and related parameters). 4. Please take out the batteries if you wull not use this product for a long time . The receiver wiring instructions Turn off the power supply before installation.
