Inching mode: press the remote control the relay will connect, and then release the remote controlto disconnect the relay; 2. Self-locking mode: press the remote control the relay will connect, and then press the remote control again to disconnect the relay; 3. Interlock mode: press the remote control key A to connect the relay, and press the remote control key B to disconnect relay. 4. Delay mode: press the remote control the relay will connect, release the remote control and start timing. After 5S, 10S and 15S (3 gears), the relay will be automatically closed. Learning Methods: 1. Inching learning method: Press the code pairing button on the control panel once, and the LED indicator will flash once. After the LED indicatorlit, press the button you need to pairing on the remote control, the LED indicator on the control panel will flash for 3 times which means the pairing succeed. 2. Self-locking learning method: Press the code pairing button on the control panel twice, and the LED indicator will flash twice. After the LED indicatorlit, press the button you need to pairing on the remote control, the LED indicator on the control panel will flash for 3 times which means the pairing succeed. 3. Mutual lock learning method: Press the code pairing button on the control panel three times, and the LED indicator will flash three times. After the LED indicatorlit, press the button you need to pairing on the remote control, the LED indicator on the control panel will flash for 3 times which means the pairing succeed. 4. 5S delay learning method: Press the code pairing button on the control panel four times, and the LED indicator will flash four times. After the LED indicatorlit, press the button you need to pairing on the remote control, the LED indicator on the control panel will flash for 3 times which means the pairing succeed. 5. 10S delay learning method: Press the code pairing button on the control panel five times, and the LED indicator will flash five times. After the LED indicatorlit, press the button you need to pairing on the remote control, the LED indicator on the control panel will flash for 3 times which means the pairing succeed. 6. 15S delay learning method: Press the code pairing button on the control panel six times, and the LED indicator will flash six times. After the LED indicatorlit, press the button you need to pairing on the remote control, the LED indicator on the control panel will flash for 3 times which means the pairing succeed. -Clearing the code : Push the learning button on the receiver 8 times , the codes will be reset. After clearing the code, remotes will be need to be recalibrated _x000D_
