5. Function description and mode setting
Receiving module
When the module is powered on and started, the red and blue LEDs will light up for configuration, and then go off to represent the completion of configuration. After this, if the red LED blinks twice, it represents the receiving mode, and the blue LED blinks twice, it represents the transmitting mode.
Momentary mode:
Press the learning button of the receiving module once. The red indicator will be on after flashing once. Press the key of the transmitting module to be matched, and the red indicator of the receiving module will flash 5 times, indicating that the matching is successful. After that, press and hold the button of the matched transmitting module; the output pin of the receiving module outputs a high level. Release the button; the corresponding pin output of the receiving module becomes low level. Each time the receiving module receives a signal, the transmitting module will receive a feedback signal, and the blue indicator will flash for 3 times and then go out.
Toggle mode:
Press the learning button of the receiving module twice. The red indicator will flash for 2 times and then be on normally. Press the key of the transmitting module to be matched, and the red indicator of the receiving module will flash for 5 times, indicating that the matching is successful. After that, press the key of the matched transmission mode; the output pin on the receiving module outputs a high level and remains unchanged. Press the same key again; the corresponding pin output of the module becomes low level. Each time the receiving module receives a signal, the transmitting module will receive a feedback signal, and the blue indicator will flash for 3 times and then go out.
Latched mode:
Press the learning button of the receiving module for 3 times, and the red indicator will be on after flashing for 3 times. Press the button of the transmitting module to be matched, and the red indicator of the receiving module will flash for 5 times, indicating that the matching is successful. Then, press the key of the matched transmission mode, and the corresponding output pins on the receiving module output high level, which remains unchanged, and other pins output low level. If two keys are pressed at the same time, all output pins on the receiving module output low level, which remains unchanged. Each time the receiving module receives a signal, the transmitting module will receive a feedback signal, and the blue indicator will flash three times and then go out.
Clear code reset function:
After pressing the learning button of the receiving module for 8 times, the red indicator light on the receiving module flashes for 8 times and then goes out. All output pin outputs become low level, and all stored transmission module addresses on the receiving module are cleared.
Mode conversion function:
After pressing the learning button of the receiving module for 5 times, the red indicator on the receiving module flashes 8 times, the module switches from the receiving mode to the transmitting mode, and the red indicator on the receiving module flashes twice, indicating that the conversion is successful.
Transmitting module
Mode conversion function:
After pressing the learning button of the receiving module for 5 times, the red indicator on the receiving module flashes 8 times, the module switches from the receiving mode to the transmitting mode, and the red indicator on the receiving module flashes twice, indicating that the conversion is successful.
Transmitter Module Startup:
When the module is powered on and started, the red and blue LEDs will light up for configuration, and go off to represent the completion of configuration. After which, if the red LED blinks twice, it represents the receiving mode, and the blue LED blinks twice, it represents the transmitting mode.

Matters Needing Attention
- RF devices are voltage-sensitive devices. If the power supply is unstable or the ripple is large, please add a filter at the power input to ensure that the power supply voltage does not exceed the maximum working voltage of the product.
- This device is an electrostatic sensitive device, and anti-static measures must be taken during transportation and use.
- Make sure that the temperature does not exceed 245 °C when mounting.
- It is recommended not to use a spring antenna with rubber in applications to ensure better yield of products.
- This product manual is subject to change without notice.
