4.2 Pairing Transmitter and Receiver
The transmitter and receiver are typically pre-paired from the factory. If re-pairing is needed or you wish to add more transmitters, follow these steps:
- Connect to Power Source: Connect the receiver to its power source. The green power indicator will turn on after the receiver is connected.
- Clear Code (Optional): To clear existing pairings, press the Programming Button on the receiver for 5 seconds until the red signal indicator turns ON and then OFF. Release the key. This indicates that the code clearance is complete, and all previous pairings are removed.
- Choose Operating Mode: After clearing the code (or if not clearing), press the programming button for a few seconds until the red and green indicators start to flash.
- Momentary (Jog): Release the key after the indicators blink once.
- Latched: Release the key after the indicators blink twice.
- Toggle: Release the key after the indicators blink three times.
- Pairing: After choosing the operating mode, press the programming button on the receiver until the red indicator is lit up. Then, press the button on the transmitter you wish to pair. The red indicator on the receiver will blink once and go out, indicating successful pairing. You will hear a click sound from the relay.

5. Operating Modes
The eMylo RF Relay Switch supports different operating modes, which determine how the relay responds to remote control presses. The available modes depend on the number of buttons on your transmitter and the number of channels on the receiver.
5.1 Mode Descriptions
- Momentary Mode: The relay remains active only as long as the remote button is pressed. Releasing the button turns the relay off.
- Latched Mode: Pressing the remote button turns the relay ON. Pressing the same button again turns the relay OFF.
- Toggle Mode: Pressing button A turns the relay ON. Pressing button B turns the relay OFF. (Requires a 2-button transmitter).

6. Maintenance
- Keep the relay module and remote controls clean and dry.
- Avoid dropping the devices or exposing them to strong impacts.
- If remote control range decreases, consider replacing the battery in the remote.
- Do not attempt to repair the internal components unless you are a qualified professional.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Relay not responding to remote. | Not paired, out of range, low remote battery, power issue to receiver. | Re-pair the remote and receiver. Check remote battery. Ensure receiver has power. Reduce distance between remote and receiver. |
| Intermittent operation. | Interference, weak signal, loose wiring. | Check wiring connections. Relocate receiver to minimize interference. |
| Relay clicks but appliance doesn't turn on/off. | Incorrect wiring to appliance, appliance fault. | Verify appliance wiring according to diagram. Test appliance independently. |
