2. Setup

2.1 Unpacking and Components

Carefully unpack all components. The package should contain:

• 2 x Wireless Remote Transmitters (with batteries included)
• 1 x Wireless Receiver Module

Connect your device and power supply to the receiver's terminal block according to the following labels:

• NO: Normally Open contact
• CM: Common contact
• NC: Normally Closed contact
• +: Positive power input
• -: Negative power input
• GND: Ground
• D1: Data input (if applicable for advanced configurations)

Refer to the wiring diagram of the device you intend to control for proper connection to the NO, CM, or NC terminals. Ensure the power supply matches the receiver's voltage requirements.

2.3 Pairing Transmitters with the Receiver

The receiver can store up to 140 unique codes from various transmitters. To pair a transmitter:

1. Ensure the receiver is powered on.
2. Locate the learning button or programming jumper on the receiver (exact location may vary, refer to receiver's specific markings).
3. Press and hold the learning button on the receiver until an indicator light (LED) illuminates or flashes, indicating it is in learning mode.
4. Within a few seconds, press the desired button on the transmitter that you wish to pair.
5. The receiver's indicator light should change (e.g., flash rapidly, turn solid, or turn off) to confirm successful pairing.
6. Repeat the process for any other buttons on the same transmitter or for additional transmitters you wish to pair.

To clear all stored codes from the receiver, typically press and hold the learning button for a longer duration (e.g., 8-10 seconds) until the indicator light confirms the reset.

3. Operating Instructions

3.1 Basic Operation

Once paired, operating the system is straightforward. Each button on the transmitter corresponds to a specific action or device linked during the pairing process.

To activate a connected device, simply press the corresponding button on the remote transmitter. The blue LED on the transmitter will illuminate when a button is pressed, indicating signal transmission.

3.2 Controlling Devices

The system is versatile and can be used for various home automation tasks:

• Garage Doors/Gates: Press the assigned button to open or close your garage door or gate.

• Indoor Lighting/Blinds: Integrate with indoor lighting systems or motorized blinds for convenient control.

4. Maintenance

4.1 Cleaning

Wipe the transmitters and receiver with a soft, dry cloth. Do not use abrasive cleaners, solvents, or immerse the devices in water. Ensure the receiver's terminal block remains free of dust and debris.

4.2 Battery Replacement (Transmitters)

The transmitters come with batteries included. If the blue LED on the transmitter does not illuminate or the range decreases significantly, it may be time to replace the battery. Refer to the transmitter's casing for the battery type (typically a small coin cell battery). Carefully open the battery compartment, replace the old battery with a new one of the same type, observing polarity, and close the compartment securely.

4.3 Storage

Store the system components in a cool, dry place away from direct sunlight, extreme temperatures, and high humidity when not in use for extended periods.

5. Troubleshooting

5.1 No Response from Device

• Check Power: Ensure the receiver module is properly powered.
• Check Pairing: Verify that the transmitter is correctly paired with the receiver. If unsure, repeat the pairing process (Section 2.3).
• Check Transmitter Battery: Confirm the transmitter battery is not depleted. Replace if necessary.
• Check Wiring: Ensure all wires are securely connected to the receiver's terminal block and to the controlled device.

5.2 Limited Range or Intermittent Operation

• Obstacles: Large metal objects, concrete walls, or other electronic devices can interfere with the wireless signal. Try operating closer to the receiver or repositioning the receiver.
• Interference: Other wireless devices operating on similar frequencies (433.92 MHz) can cause interference.
• Low Battery: A weak transmitter battery can reduce the effective range.

5.3 Receiver Indicator Light Not Functioning

• Power Issue: Ensure the receiver is receiving adequate power.
• Damage: If the receiver has been exposed to moisture or physical damage, it may be faulty.
