power input 12VDC or 24VDC;   frequency: 433MHz;   control distance: 20 to 500M( in the open area only for 500m)   1. Working method       1. Signal self-locking - press the No. 1 button on the remote control       2. Signal interlock - press the No. 2 button on the remote control       3. Signal 3-way self-locking and 3-way non-locking co-exist - press the No. 3 button on the remote control       4. The signal is not locked - press the No. 4 button on the remote control       5. Signal 1-way self-locking and 5-way non-locking coexist—press the No. 5 button on the remote control       2. Output method       APDC-6K has 5 output modes: signal self-locking, signal interlocking, signal non-locking, signal non-locking and self-locking coexistence       1. Signal self-locking: press button 1 on the remote control to learn       Press the 1 key on the remote control, the relay corresponding to the 1 key will absorb and hold, and then press the 1 key, the 1 relay will be disconnected; press the remote control 2 key, the 2 key corresponding to the relay will absorb and hold, and then press the 2 key, the 2 relay will be disconnected; 3, 4, 5, 6 keys work in a cycle like this.       2. Signal interlock: press the No. 2 button on the remote control       Press the 1 key on the remote control, the corresponding 1 relay will absorb and hold, press the 2 key, the 1 relay will be disconnected, and the relay corresponding to the 2 key will absorb and hold; 3, 4, 5, 6 keys work in this cycle.       3. The signal is not locked: press the No. 4 button on the remote control       Press and hold the 1 button on the remote control, the relay corresponding to the 1 button will be closed, and the relay will be disconnected after releasing it, press the 2 button, the relay corresponding to the 2 key will be closed, and it will be disconnected after releasing it; 3, 4, 5, The 6 keys work in this cycle       4: Signal 3-way self-locking and 3-way non-locking coexist: press the No. 3 key on the remote control       Of the 6 relays corresponding to the remote control, 1, 2, and 3 are self-locking, and 4, 5, and 6 are non-locking.       5. Signal 1-way self-locking and 5-way non-locking coexist: press the No. 5 key on the remote control       Of the 6 relays corresponding to the remote control, 1 is self-locking, and 2, 3, 4, 5, and 6 are non-locking.       study method:       1. Press the learning button on the receiver for about 2 seconds, then let go and enter the learning state; press a button on the remote control to learn according to the function you need, and the indicator light flashes about 4 times after the receiver receives the signal, indicating that Learn to succeed.       Clearing method:       Press and hold the learning button on the receiver for about 8 seconds until the indicator light flashes twice and then goes out, indicating that it has been cleared successfully. This receiver can store about 30 remote controls with different codes.       4. Main technical indicators
