Features: 1. This controller is controlled by intelligent microprocessor, which can be used control of garage door, lighting control, curtain control, door control system, etc. 2. Easy to install, small size, and reliable.Specifications: Operating voltage: DC 12V Operating temperature: -40~80 degrees Operating frequency: 433MHZ Receive sensitivity: ≥-95dB Working Mode: jump switch, point action, self locking, and interlocking(adjustable) Remote control distance: 20-40m/65.61-131.23ft Product size: Switch size: approx. 40 x 40 x 25mm/1.57 x 1.57 x 0.98in Remote Control size: approx. x 40 x 12mm/1.96 x 1.57 x 0.47in Product weight: Control panel weight: approx. 24g Remote control weight: approx. 20g Material: ABSOperation Manual: Press the learn button for 2 or 3 seconds, lights out (that has entered the state of learning), Release the learning button, press any key of the remote control, and the indicator flashes 5 times to show the success of the study. Note: The controller can learn the fixed code / learning code, total 16 different encoding, arbitrary button remote control, and beyond will be cleared early learning of remote control.Removal method: Continue to hold down the learning button for about 8 seconds. The indicator is extended from extinction to success.Work mode switching: Connect a 12V DC output: the learning of the single remote control switch 12V input, connect a 12V DC power supply, the output from 12V positive public end, often beginning the positive on the output side of the bulb, the bulb of the cathode received power of the cathode, a simple control bulb circuit is designed.
