Specification: Item Type: Remote Control Switch Material: PCB Operating Current: Less than or Equal to 18mA Oscillation Mode: Saw Resonator Oscillation Resistance: 270K Modulation Method: Ask OOK Operating Frequency: 433.92MHz Frequency Deviation: 0.2MHz Coding format: million group codes (EV1527) Transmitting power: 15mW Data transmission rate: 50 to 60KHZEV1527 working distance: approx. 100m/328.1ft Wireless receiving sensitivity: -108dbm Maximum transmitter load capacity: DC 1-110V, 5A; AC 85-265V, 6A Remote Control Battery: 12V 23A Battery x 1 [Supplied Without Battery] Package List: 1 x Control Board 1 x Remote Control How to use: Adapter Remote Control (for learning remote control): 1. In normal working mode, the LED is always on, and when the remote key receives the correct value, the LED will flash.2. Clear code: long press the button, the LED will turn off. After about 5 seconds, the LED is on and the code clearing is completed (Note: After performing code clearing, there is no previously saved remote control, if you want to use the old remote control, please relearn).3. Adaptation (Learning): Step 1 (Remote Control Matching): Press any key on the remote control, if the LED flashes quickly, it means it is a matching remote control, otherwise it is not a matching remote control. Step 2 (Enter into learning mode): touch the button, the LED turns off. Step 3 (learning the remote control): press any key on the remote control within 10 seconds, the LED flashes 3 times and then lights up, indicating learning successful; If the LED only flashes 2 times, it means learning has failed, Indicates learning has been completed. Remote learning; Learning completed.
