Operating instructions for working mode:

Press the code matching button on the control panel 8 times continuously, and the LED indicator will flash 8 times. At this time, the LED indicator will flash 8 times continuously, then the code is cleared and all the remote control key codes learned before are cleared. According to the prompts, select the desired working mode [number of times] for code matching.

1. Jog function:

Press the control panel pairing button once, and the LED indicator will flash once. After the LED indicator lights up, press the remote control button that needs to be paired, and the control panel LED indicator will flash 3 times in succession.

2. Self-locking function:

Press the control panel pairing button twice, and the LED indicator will flash twice. After the LED indicator lights up, press the remote control button that needs to be paired, and the control panel LED will flash 3 times in succession.

3. Interlock function:

Press the control panel pairing button 3 times, the LED indicator flashes 3 times, and the LED indicator lights up. Press the button of the remote control that needs to be coded, the LED indicator on the control panel flashes 3 times in a row, and the code is successfully coded.

4. Delay 5 seconds:

Press the code matching button on the control panel 4 times, the LED indicator flashes 4 times. After the LED indicator lights up, press the remote control button that needs to be coded, and the control panel LED indicator flashes 3 times in a row. The code is successful.

5. Delay 10 seconds:

Press the control panel pairing button 5 times in a row, and the LED indicator will flash 5 times. After the LED indicator lights up, press the remote control button that needs to be paired. The control panel LED indicator flashes 3 times in a row and the code is successfully matched.

6. Delay 15 seconds:

Press the code matching button on the control panel 6 times continuously, and the LED indicator will flash 6 times. After the LED indicator lights up, press the remote control button that needs to be coded, and the control panel LED indicator flashes 3 times in succession.

7. Delay 20 seconds:

Press the code matching button on the control panel 7 times, the LED indicator flashes 7 times. After the LED indicator lights up, press the remote control button that needs to be coded, and the control panel LED indicator flashes 3 times in succession.

Note: Set the delay mode, if you keep pressing the button during use, it will continue to delay continuously
