Only one relay can be active at a time. - Interlock: Press one button to activate its relay and deactivate any other active relay. Only one relay remains active at a time. - Self-locking: Each button toggles its relay on and off independently. Press once to turn on, press again to turn off. Mode Selection & Pairing Instructions: - Momentary Mode: Learn using the "3" button. All 12 relays will operate in momentary mode. Press button "1" to activate relay A1, release to deactivate. Applies to all relays. - Interlock Mode: Learn using the "6" button. All 12 relays will operate in interlock mode. Press button "1" to activate A1 and deactivate others. Press button "2" to activate A2 and deactivate others. Only one relay active at a time. - Self-locking Mode: Learn using the "9" button. All 12 relays will operate in self-locking mode. Press button "1" to turn A1 on, 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 a signal response and another buzzer sound. Clearing Procedure: Long-press the learning button on the receiver for approximately 10 seconds until the buzzer sounds. This clears all stored remote data.
