Only one relay can be active at a time. - Interlock: Press one button to activate its relay and deactivate any previously active relay. Only one relay is active at a time. - Self-locking: Each button toggles its relay on and off independently. Two independent control channels. Mode Selection & Pairing Instructions:- Momentary Mode: Learn using the "3" button. All 12 relays operate in momentary mode. Press button 1 to turn on A1 relay, release to turn it off. Applies to all relays. - Interlock Mode: Learn using the "6" button. All 12 relays operate in interlock mode. Press button 1 to activate A1 and deactivate others; press button 2 to activate A2 and deactivate others. - Self-locking Mode: Learn using the "9" button. All 12 relays operate in self-locking mode. Press button 1 to turn on A1; press again to turn it off. Each relay operates independently. Learning Procedure: Press the learning button on the receiver. Press any button on the remote after the buzzer sounds. Successful pairing is confirmed by signal reception and another buzzer sound.Clearing Procedure: Long-press the learning button on the receiver for about 10 seconds until the buzzer sounds. This clears all stored data.Package List:- 1 x 12 Channel Relay - 1 x Remote Controller
