2. Pairing with a Receiver
This transmitter must be paired with a compatible 433 MHz RF receiver (sold separately) to function. The pairing process typically involves setting the receiver into a learning mode and then pressing a button on the transmitter. Refer to the specific instructions provided with your receiver for detailed pairing procedures. The transmitter supports three operating modes: Momentary, Latched, and Toggle, which are configured on the receiver.
Operating Instructions
Once paired with a receiver, the 4 keys (A, B, C, D) on the transmitter will control the connected device(s) according to the programmed mode.
Operating Modes:
- Momentary Mode: The output is active only while the button is pressed. Releasing the button deactivates the output. This mode is typically available for 1, 2, 3, or 4 buttons.
- Latched Mode: Pressing a button activates the output, and it remains active until another button is pressed to deactivate it. This mode is typically available for 1, 2, 3, or 4 buttons.
- Toggle Mode: Pressing a button activates the output. Pressing the same button again deactivates the output. This mode is typically available for 2, 3, or 4 buttons.
The specific function assigned to each button (A, B, C, D) and the operating mode are determined during the pairing process with your receiver. Consult your receiver's manual for configuration details.

Maintenance
Battery Replacement:
When the remote control's range decreases or it becomes unresponsive, it may be time to replace the batteries. Follow the battery installation steps outlined in the Setup section.
Cleaning:
Wipe the transmitter with a soft, dry cloth. Avoid using harsh chemicals or abrasive cleaners, as these can damage the casing or internal components.
Troubleshooting
- Remote not responding: Check if the batteries are correctly installed and have sufficient charge. Replace batteries if necessary. Ensure the remote is within the operational range of the receiver.
- Reduced operating range: This often indicates low battery power. Replace the batteries. Environmental interference or physical obstructions can also affect range.
- Incorrect function: If the buttons are not performing the expected actions, the transmitter may need to be re-paired with the receiver, or the receiver's programming may need to be reconfigured. Refer to your receiver's manual.
