4. Setup (Programming)
To program your new remote control, you will need to pair it with your existing gate or garage door opener's receiver. The process is similar to programming original SOMMER remotes. Always refer to your specific receiver's user manual for the most accurate instructions. Below is a typical programming procedure for a SOMMER Radio Receiver FM 868.8MHz:
- Access Learning Button: Press the LEARNING button on the radio receiver or on the control panel.
- Select Channel: Press the LEARNING button once for channel one (LED 1 lights up), or twice for channel two (LED 2 lights up).
- Transmit Signal: Within the range of the radio receiver, press one of the desired CH buttons on your new remote control. The LED on the receiver will flash and then extinguish, indicating successful pairing to the selected channel.
- Repeat for Additional Remotes: Repeat steps 1 and 2 to teach further manual remote controls to the given radio receiver. A maximum of 112 memory slots are typically available.
- Test Operation: Press the programmed button on your new remote control to test its operation.
Note:
- To remove a single transmitter's code or all transmitter codes from the receiver memory, please refer to your specific receiver manual.
- Ensure you are within close proximity to the receiver during the programming process.

5. Operating Instructions
Once successfully programmed, operating your remote control is straightforward:

- Press the corresponding button on the remote control that you programmed for your specific function (e.g., open, close, stop).
- The garage door or gate should respond accordingly.
6. Maintenance
6.1 Battery Replacement
The remote control uses a CR2032 coin cell battery. When the remote's signal weakens or stops working, it's likely time to replace the battery.
- Carefully open the remote control casing. This may involve unscrewing small screws or prying open a seam with a small flat-head screwdriver.
- Remove the old CR2032 battery.
- Insert a new CR2032 battery, ensuring the correct polarity (+/-).
- Close the remote control casing securely.
6.2 General Care
- Keep the remote control dry and away from extreme temperatures.
- Avoid dropping the remote control or subjecting it to strong impacts.
- Clean the remote control with a soft, dry cloth. Do not use harsh chemicals or abrasives.
7. Troubleshooting
- Remote not working after programming: Double-check the programming steps against your receiver's manual. Ensure the battery is correctly installed and has sufficient charge.
- Reduced operating range: The transmit distance is 25-50m in open space. Obstructions such as garage doors, brick walls, or other interference can significantly reduce the remote control's range. Try operating the remote from a closer distance or in a less obstructed area.
- LED on remote does not light up: The battery may be dead or incorrectly installed. Replace the battery.
- Remote works intermittently: This could indicate a low battery. Replace the CR2032 battery.
8. User Tips
- Verify Compatibility: Before purchasing, always confirm that your existing garage door or gate opener model is listed as compatible to ensure seamless integration.
- Optimal Range: For best performance, try to maintain a clear line of sight between the remote and the receiver. Physical barriers can significantly impact signal strength.
- Button Capacity: This remote features 4 buttons, allowing you to program up to four different functions or devices if your receiver supports multiple channels.
