- Press and Hold Remote Button: Press and hold the button on the remote control that you wish to program for opening/closing the garage door.
- Confirm Programming: Continue holding the button until the red indicator light on the control unit stops flashing rapidly and then extinguishes. This indicates successful programming.
- Test Remote: Release the button on the remote control. Test the remote by pressing the programmed button. The garage door should now operate.
Note: Ensure your garage door opener is compatible with the SOMloq2 radio system and the 868.8 MHz / 868.95 MHz frequencies. Some regional variations of Sommer products exist; verify compatibility if issues arise.

5. Maintenance and Battery Replacement
The remote control is powered by one CR123A battery. When the remote's range decreases or it stops responding, the battery may need replacement.
Battery Replacement:
- Open Casing: Carefully open the remote control casing. This typically involves gently prying apart the two halves or removing a small screw if present.
- Remove Old Battery: Remove the old CR123A battery from its compartment.
- Insert New Battery: Insert a new CR123A battery, ensuring correct polarity (+ and -).
- Close Casing: Close the remote control casing securely until it clicks into place.
Dispose of old batteries responsibly according to local regulations.
Cleaning:
Clean the remote control with a soft, dry cloth. Do not use abrasive cleaners or solvents.
6. Troubleshooting
If your Sommer Slider+ S10305 remote control is not functioning as expected, consider the following:
- Remote not responding:
- Check the battery. Replace it with a new CR123A battery if necessary.
- Ensure the remote is within the operating range (50-140 meters) of the receiver.
- Verify that the remote is correctly programmed to your garage door opener. Repeat the programming steps if unsure.
- Reduced range:
- Replace the battery.
- Check for sources of interference (e.g., other radio devices, large metal objects, thick walls) near the remote or the receiver.
- Ensure the antenna on your garage door opener is unobstructed.
- Remote programmed but not working (especially in certain regions):
- Some Sommer products have regional codes (e.g., S10305-0001 vs. S10305-00075). Ensure the specific model you have is compatible with your region's garage door opener. Incompatible regional codes can prevent proper function.
- Consult your garage door opener's manual or the manufacturer for regional compatibility information.
